New functions compared to PN/PN Coupler up to V4.0

New functions of PN/PN Coupler in firmware version V4.2 The following table lists the new functions of the PN/PN Coupler.

Table 2- 1 New functions of the PN/PN Coupler with FW version 4.2 compared with firmware version V4.0

New functions Applications

System redundancy S2

The S7-1500R/H or S7-400H redundant system offers a high degree of reliability and system availability. A redundant configuration of the most important automation components reduces the probability of production downtimes and the consequences of component errors.
The higher the risks and costs of a production downtime, the more worthwhile the use of a redundant system. You can compensate for the generally higher investment costs by avoiding production downtimes.

PN/PN Coupler as docking station

The PN/PN Coupler as a docking station can operate several docking units. These are operated as "Tool Changers" on the PN/PN Coupler.

Local data record With local record transfer, you pro-

transfer

vide a copy of your data records to

up to 3 CPUs at the same time.

Customer benefits

Where can I find the information?

In redundantly operated systems, failure or malfunction of individual automation components must not impede the operation of the plant. Redundant systems are used in the following areas, for example:

Section System redundancy S2 (Page 79)

� Power plants

� Steel mills

� Wastewater treatment plants � Shipbuilding

� Tunnel

� Subways � Baggage handling systems

� Highbay storage

� Airports

You can use the PROFINET "Tool

Product overview 2.2 Area of application and function

2.2

Area of application and function

Area of application and customer benefits You use the PN/PN Coupler in order to:
Interconnect two PROFINET subnets with system redundancy S2
Interconnect two Ethernet subnets
Exchange data
Share or couple data with up to 4 IO controllers
To do this, use:
User data via input or output address ranges which can be separated or coupled
Shared input/shared output or local shared output
Data records or local data records
The maximum size of the transferable input and output data is:
1440 bytes of input data and 1440 bytes of output data
1000 bytes of inputs and 1000 bytes of outputs with system redundancy S2
1440 bytes of input data and 1440 bytes of output data with system redundancy S2 and Shared Device. Each number is the total for all IO controllers involved. For system redundancy S2 the input/output length is counted twice (see also System redundancy S2 (Page 79)).
The input and output data can be divided as desired. For example, you configure 1200 bytes of input data and 1340 bytes of output data.
The PN/PN Coupler is a device with two PROFINET interfaces that are each connected to a subnet.
The two subnets are electrically isolated.
During configuring, STEP 7 creates two IO devices with their subnets from a PN/PN Coupler. The other part of the PN/PN Coupler in each case is known as the coupling partner.

Product overview 2.2 Area of application and function
Principle of operation
Data exchange with I/O modules:
Through the configured inputs of a slot, the local CPU reads the values that the CPU of the other subnet writes over the configured outputs of the coupling partner. Through the configured outputs of a slot, the local CPU writes values that the CPU of the other subnet receives over the configured inputs of the coupling partner.
Data record transfer:
The module types Publisher and Storage are available. Each type consists of Read and Write modules (see Assignment of the modules (Page 38)). These modules receive address areas which have to be specified for the data record job (see How cross-network data record transfer works (Page 52)).
System redundancy S2
You can connect redundantly-configured subnets to each other via a PN/PN Coupler. A system-redundant and a non-system-redundant subnet can also be connected (see System redundancy S2 (Page 79)).
Using a redundancy system with S7-1500R/H or S7-400H is required for the implementation of system-redundant subnets. The redundant system consists of two high-availability controllers (lead and redundant CPU). The IO devices used in the subnet connected with system redundancy must also support system redundancy.

Introduction

Redundant 24 V DC power supply
You can connect the PN/PN Coupler to two independent 24 V DC power supplies (SELV/PELV). Only one 24 V DC power supply is active at a time. If one power supply fails, the other becomes active automatically. You identify which power supplies (PS1, PS2 or both) are connected and will be diagnosed in the parameter assignment. The connection of one 24 V DC power supply is generally sufficient for operation of the PN/PN Coupler.

Properties of the PN/PN Coupler The two PROFINET IO subnets are galvanically isolated from each other. The two PROFINET IO subnets are galvanically isolated from the 24 V DC power supply. The two 24 V DC power supplies are galvanically isolated from each other.

Ungrounded infeed
It is always possible to configure an ungrounded setup of the PN/PN Coupler as the PN/PN Coupler has no fixed ground connection. The power pack/power supply module for 24 V DC must also be ungrounded and electrically isolated.

Connecting the power supply

Required tools You need a screwdriver with a maximum blade width of 3.5 mm to connect the power supply.
Power supply unit Only SELV/PELV power supplies with safe, electrically isolated, safety extra-low voltage ( 60V DC) may be used.
Redundant power supply You can supply the PN/PN Coupler from two voltage sources (redundant power supply): If one voltage source fails, the PN/PN Coupler automatically switches over to the other voltage source. If voltage is applied to both connections (PS1 / PS2), the PN/PN Coupler automatically uses the voltage source of PS1. If you only connect the PN/PN Coupler to one power supply, it is preferable to connect it to PS1.
Note You can evaluate the diagnostics to determine whether the PN/PN Coupler is connected to both 24 V DC power supplies.

Configuring, parameter assignment and commissioning 5.3 Assignment of the modules

PROFIsafe module
You have to observe the following for PROFIsafe IN/OUT:
Only the PROFIsafe IN/OUT must be used for failsafe communication in module operating mode "IO Modules".
The data status byte is not available, because the validity of the coupled user data is guaranteed by the mechanisms of the failsafe communication.
We recommend that you do not use the respective modules for other applications due to the missing data status byte (DS).
Note Safety-related communication
For safety-related communication between F-CPUs S7-1500/1200 and a configured PN/PN Coupler from the integrated hardware catalog, the fail-safe instructions "SENDDP/RCVDP" support "IO Modules" as well as "IO Modules (ext. V3.x comp.)".
For safety-related communication with F-CPU S7-300/400, use the fail-safe instructions "SENDDP/RCVDP" and the "IO Modules (ext. V3.x comp.)".

You will find details in the table below:

Configuring the PN/PN Coupler with STEP 7 TIA Portal

Configuration of the PN/PN Couplers 1. Start STEP 7 TIA Portal with your project and open the hardware configuration.
2. Drag PN/PN Coupler 6ES7158-3AD10-0XA0 from the Network components/Gateways directory of the hardware catalog to the PROFINET network.
3. Double-click the symbol of the PN/PN Coupler.
4. Assign a device name for the PN/PN Coupler and confirm with OK.
The device name must be unique on the Ethernet subnet. The device name must comply with the DNS conventions. You can find more information about assigning the device name in the STEP 7 online help.
5. For configuring the left side of the bus (X1), click the symbol of the PN/PN Coupler.
6. Open the "Module parameters/Transfer mapping" table in PNPN Coupler.x1. Create up to 16 slots of the PN/PN Coupler in the table. Note the permitted assignment of modules (see Assignment of the modules (Page 38)).
Note Assigning the device name
Assign the device name to the PN/PN Coupler online.

Result

Configuring is complete for both sides of the PN/PN Coupler.

Coupling both subnets The two sides are constantly kept consistent in the TIA Portal. Changes to side X1 lead automatically to the adaptation of side X2, and vice versa. This requires that the two bus sides X1 and X2 are in the same project or in a multi-project.
Recommended procedure when you make changes on the couple partner: 1. Perform the changes (e.g. add I/O modules). 2. Execute the "Save and compile" function for both bus sides. Result: The configuration is consistent.

Configuring the PN/PN Coupler with a different configuration tool

Introduction

You configure the PN/PN Coupler using a GSD file. You integrate the PN/PN Coupler as an IO device in your configuration tool using this file. The GSD files can be downloaded on the Internet (https://support.automation.siemens.com/WW/view/en/23742537).

GSD file

The following GSD file is available for the PN/PN Coupler: GSDML-V2.34-Siemens-PNPNIOC-"Date in format yyyymmdd".xml You can find more information on the procedure with GSD files in the STEP 7 online help.

Configuring the PN/PN Coupler
You configure the PN/PN Coupler with your configuration tool like any other IO device on PROFINET IO.
Download the complete GSD file for the PN/PN Coupler to your configuration tool. You configure the PN/PN Coupler separately in each of the two subnets. Select the IO device labeled with X1 or X2 in each case.
Note the following when assigning the device name for the PN/PN Coupler: The device name must be unique on the Ethernet subnet. The device name must comply with the DNS conventions.
When configuring using a GSD file, various modules are available for the data record transfer, each of which has a fixed length. Support for configuring the coupling of the two subnets (as is available in STEP 7) is not possible when configuring using a GSD file. Note the permitted assignment of modules (see Assignment of the modules (Page 38)).

IO modules in two versions
The GSD offers IO modules in two versions:
IO Modules (recommended)
The validity of the coupled user data is displayed in the input data due to the included data status byte (DS).
IO Modules (ext. comp. V3.x)
In this operating mode, monitoring of the user data validity is ensured by the PROFINET system by transfer and coupling of the user data flags IOxS. To do so, the information for evaluation of user data validity is provided by the organization blocks (error OB 85 or 122) in the SIMATIC CPU. You check the availability of the submodules first after the device has returned in OB86. For submodules that do not become available until after the device has returned (e.g. by including a submodule in the same slot on the other bus side), the PN/PN Coupler sends a ReturnOfSubmodule alarm to the controller that results in a OB83 call within a SIMATIC CPU. In operating mode IO Modules (ext. comp. V3.x), the PN/PN Coupler is compatible with the PN/PN Coupler V3.0.

In operating mode IO Modules (ext. comp. V3.x), the PN/PN Coupler is compatible with the PN/PN Coupler V3.x.
Note IO Modules are not compatible with IO Modules (ext. comp. V3.x) It is not permitted to mix operating modes on the local or the partner interface. This must also be ensured when using the PN/PN Coupler as PROFINET shared device with multiple controllers.

You can assign the parameters separately for the two sides of the PN/PN Coupler.

STEP 7 generates interrupts (e.g. when monitoring a power supply) separately for each side.

Voltage check PS1 / PS2
If you have enabled the voltage check PS1 / PS2, the PN/PN Coupler diagnoses the failure of the power supply on the two bus sides independent of one another. Only activate the voltage check if the corresponding power supply is actually connected.

Diagnostics Undervoltage
An undervoltage diagnostics is triggered when the supply voltage drops below 19.2 V.
Once the supply voltage exceeds 20.4 V again, an undervoltage diagnostics is no longer shown.
If the voltage falls below the lower voltage limit at only one of the two feeds, the diagnostics is not yet triggered, because measurements are taken at the common internal voltage supply (see Block diagram (Page 35)).
The undervoltage diagnostics is supported from hardware function status FS04 according to the above description and is displayed as a maintenance interrupt after being enabled via the module parameters (Interrupts (Page 94)).

You use the data validity display DIA to determine whether or not the IO controller connected via the PN/PN Coupler still supplies valid data from the "other" subnet.
Only activate the data validity display DIA if you have configured inputs on the relevant side of the PN/PN Coupler. Modules for the data record transfer are not taken into consideration for this.
The validity of the data is always displayed in bit 0 of the least significant input byte of the PN/PN Coupler: The least significant input byte is the lowest slot number of the first input module.

Bit 0 = 1: received data are valid. Bit 0 = 0. received data are invalid. Possible causes: An interface of the PN/PN Coupler is faulty The PN/PN Coupler in the other subnet has failed The PN/PN Coupler in the other subnet is in STOP state.
CAUTION Incorrect program interpretation If you have activated the "Data validity display DIA", you must not use the first bit of the first configured input byte for input data or the associated first bit of the first configured output byte in the other subnet for output data!

Diagnostics for data validity
You use the diagnostics for data validity to determine if the IO controller of the other subnet is in STOP state. The online diagnostics indicates "Data invalid" for the respective slot.
This diagnostic message is selected by default and can be disabled for each interface separately.

Diagnostics for error in other network
You use the diagnostics for error in other network to determine that the other bus side has no configuration data.
This diagnostic message is selected by default and can be disabled for each interface separately.

Diagnostics for difference in network configuration
With the diagnostics for difference in network configuration, the PN/PN Coupler outputs a diagnostics interrupt indicating an invalid mapping for the two bus sites.
This diagnostic message is selected by default and can be disabled for each interface separately.

Identification data

Definition

Identification data is data that is stored in a module that supports you in: Checking the system configuration Locating hardware changes in a system Troubleshooting in a system You can unambiguously identify and localize modules online with the identification data. In STEP 7 TIA Portal, the identification data is displayed on the "Module status - PN/PN Coupler" and "Properties - PN/PN Coupler" tabs (see STEP 7 online help).

Reading the identification data
Each of the two bus sides of the PN/PN Coupler has its own memory area for identification data. You can enter and read out the identification data separately for each of the two bus sides (except I&M0).
You selectively access certain identification data using Read data record. Under the associated data record index you obtain the corresponding part of the identification data.

6.1.1

How cross-network data record transfer works

Introduction

The data record transfer via the PN/PN Coupler starting from article number 6ES71583AD10-0XA0 enables you to transfer up to 4096 bytes of data per slot acyclically from one IO controller (sender) to another IO controller (receiver). This acyclic data record transfer enables you to exceed the cyclic I/O data transfer of 1440 bytes of inputs and 1440 bytes of outputs (in total).
The PN/PN Coupler can buffer a maximum of 8 data records per slot with the Storage module type, i.e. provide for reading.
The buffer memory operates according to the first in, first out (FIFO) principle. The module type Publisher does not buffer data records, which means the data record transferred last is overwritten.

Hardware Installation and Operating Manual, 09/2019, A5E00717043-AH

Functions 6.1 Data record transfer from one IO controller to another IO controller
Principle of operation The Storage and Publisher module types are available for transferring data records. The following figure shows the sequence of the transfer of a data record from one IO controller to another:
IO controller 1 (sender) issues a write request to the PN/PN Coupler and transfers the data
record to the PN/PN Coupler.
The PN/PN Coupler transfers the data record from its sender side to its receiver side. The PN/PN Coupler sends an acknowledgment to IO controller 1 that the data record was
received.
The PN/PN Coupler indicates on its receiver side that a data record is available for reading (via
status information of the PN/PN Coupler and optionally via an update interrupt in IO controller 2 (receiver)).
Only module type Storage: IO controller 2 (receiver) reads the status information and the data
record and acknowledges the receipt. Figure 6-1 Sequence of the data record transfer

Functions 6.1 Data record transfer from one IO controller to another IO controller
Boundary conditions for data record transfer Data record transfer does not correspond to data record routing. The I/O data (status information) are not coupled as a mirror image. The data records are transferred in one direction, from the sender to the receiver. Both sides of the PN/PN Coupler must be exchanging data with the connected IO controllers. If one side is not exchanging data and data for reading has already been provided, this data is deleted when the side starts exchanging data. Data record transfer begins from a defined state when both sides are exchanging data with the IO controllers.
Note Redundancy S2 With redundancy S2, the data record transfer may have to be repeated. Not all operations for data record transfer may have been executed during switchover from the primary CPU to the backup CPU.
Data record transfer with the Storage module type The Storage module type can buffer a maximum of 8 data records per slot, i.e. provide for reading. The buffer memory operates according to the first in, first out (FIFO) principle. If the receiver has successfully read a data record, it must explicitly acknowledge this so that this data record is deleted from the buffer memory of the PN/PN Coupler, thereby allowing the next data record to be read. If a sender attempts to write a data record to the PN/PN Coupler even though its buffer memory is full, the data record will be rejected by the PN/PN Coupler.
Data record transfer with the Publisher module type The Publisher module type does not buffer data records. The sender writes only data records with the same "record_index". This "record_index" is set as a parameter of the module on the sender side. If the sender delivers the next data record, the previous data record is overwritten. The PN/PN Coupler indicates the existence of a new data record using a circulating counter on the receiver side. The receiver can read a data record as often as desired. If the receiver does not know the length of the data record, you must request the maximum possible length of 4096 bytes in the read request to ensure that the entire data record is read.

Hardware Installation and Operating Manual, 09/2019, A5E00717043-AH

Functions 6.1 Data record transfer from one IO controller to another IO controller
Configuring for the data record transfer For the data record transfer, you configure a virtual module on both sides of the PN/PN Coupler (X1 and X2). Module type Storage: "RD WRITE STO" on the sender side and "RD READ STO" on the receiver side. Module type Publisher: "RD WRITE PUB" on the sender side and "RD READ PUB" on the receiver side.
Maximum number of sender and receiver modules You can configure a maximum of 16 "RD WRITE STO", "RD READ STO", "RD WRITE PUB" and "RD READ PUB" modules for each interface of the PN/PN Coupler (max. data record length of 4096 bytes per module).

6.1.2

How local data record transfer works

Introduction

The local data set transmission via the PN/PN Coupler with article number 6ES7158-3AD100XA0 is possible as of firmware version V4.2.
Local data set transfer via the PN/PN Coupler allows you to send up to 4096 bytes of data per slot acyclically from one IO controller (sender) to up to 3 IO controllers (receiver) on the same side. This acyclic data record transfer enables you to exceed the cyclic I/O data transfer of 1440 bytes of inputs and 1440 bytes of outputs (in total).
The PN/PN Coupler can buffer a maximum of 8 data records per slot with the Storage module type, i.e. provide for reading.
The buffer memory operates according to the FIFO (first in - first out) principle. The Publisher module type does not buffer data records. A data record in the PN/PN Coupler is always updated. This means that the last data record transferred is updated when it is written again.

Principle of operation
The module types Storage (RD LOCAL STO) and Publisher (RD LOCAL PUB) are available for this transfer.
The following figure shows the transfer of a data record from one IO controller to the 3 other IO controllers.

Functions 6.1 Data record transfer from one IO controller to another IO controller
Constraints on local data record transmission Data record transfer does not correspond to data record routing. The I/O data (status information) are not coupled as a mirror image. The data records are transferred in one direction, from the sender to the receiver. One side of the PN/PN Coupler must be exchanging data with the connected IO controllers. If one side is not exchanging data and data for reading has already been provided, this data is deleted when the side starts exchanging data. Data record transfer begins from a defined state when both sides are exchanging data with the IO controllers.
Data record transfer with the Local Storage module type The Local Storage module type can buffer a maximum of 8 data records, i.e. provide for reading. The buffer memory operates according to the first in, first out (FIFO) principle. If all receivers have successfully read a data record, they must explicitly acknowledge this so that this data record is deleted from the buffer memory of the PN/PN Coupler, thereby allowing the next data record to be read. If a sender attempts to write a data record to the PN/PN Coupler even though its buffer memory is full, the data record will be rejected by the PN/PN Coupler.
Data record transfer with the Local Publisher module type The Local Publisher module type does not buffer data records. The sender writes only data records with the same "record_index". This "record_index" is set as a parameter of the module on the sender side for all receivers. If the sender delivers the next data record, the previous data record is overwritten. The PN/PN Coupler indicates the existence of a new data record using a circulating counter ("cycle_counter") on the receiver side. The receiver can read a data record as often as desired. If the receiver does not know the length of the data record, you must request the maximum possible length of 4096 bytes in the read request to ensure that the entire data record is read.
Configuration for local data record transfer For the data record transfer, you configure a virtual module on one side of the PN/PN Coupler (X1 or X2). Sender: Storage module type: "RD LOCAL STO" Receiver: Publisher module type: "RD LOCAL PUB"

Note Writing data records with RD WRITE PUB and LOCAL RD WRITE PUB
You can only write data records with the data record number specified as a parameter in advance in the hardware configuration. Setting range: 2 (default setting) to 0x7FFF.

Update interrupt (OB 56)
You can optionally enable an update interrupt in the configuration of the "RD READ STO"/"LOCAL RD READ STO" or "RD READ PUB"/"LOCAL RD READ PUB" module, that signals the receiver that a new data record is ready for reading in the buffer of the PN/PN Coupler. The update interrupt is disabled by default. A new update interrupt can only be issued when the preceding interrupt has been acknowledged in the user program.

Note
For the Publisher module type, the sender can overwrite the previous data record as often as desired. As a result, it is not guaranteed that the receiver receives an update interrupt for each new data record.

The update interrupt has interrupt type 6. The update interrupt uses the optional structure element AlarmItem, which consists of:

Functions 6.1 Data record transfer from one IO controller to another IO controller
Editing in the user program CPU 1 writes data records to the LOCAL RD WRITE STO submodule in the virtual slot 1.1. These data are available to the controllers CPU 2 to CPU 4 with the submodules LOCAL RD READ STO.
You can also use local data record transfer:
With fewer controllers
When configuring additional modules in other slots
When the RD LOCAL STO module is used, data records are cached in the buffer and all CPUs read by LOCAL RD READ STO must acknowledge a data record by writing the "ack_counter". Only then is the next data record available for reading.
You can also implement this example with RD LOCAL PUB. In this case, individual nonreading CPUs from LOCAL RD READ PUB do not block the data record transfer to other LOCAL RD READ PUB of the same module.

Device replacement

Device replacement without topology configuration
The device name is also automatically permanently stored on the SIMATIC BusAdapter in addition to the PN/PN Coupler. A device name stored in the BusAdapter is required for device replacement without topology configuration.
Storing the name on the BusAdapter and the PN/PN Coupler produces a range of scenarios for using the device name when the PN/PN Coupler is replaced.

Table 6- 4 Scenarios for using the device name

BusAdapter without a device name BusAdapter with device name

PN/PN Coupler without a device name No device name available
The device name from the BusAdapter is used and copied to the PN/PN Coupler.

PN/PN Coupler with a device name
The device name from the PN/PN Coupler is used and copied to the BusAdapter.
The device name from the BusAdapter is used and copied to the PN/PN Coupler if the device names are different

Note the following constraints:

Resetting to factory settings deletes the device name in both the PN/PN Coupler and the BusAdapter. To prevent the device name from being deleted in the BusAdapter, you can remove the BusAdapter from the PN/PN Coupler before resetting to factory settings.

When a BusAdapter is replaced, a device name stored in the BusAdapter is applied in the PN/PN Coupler after a POWER ON.

Removal/insertion of the BusAdapter under voltage is not permitted. If you nevertheless remove or insert the BusAdapter under voltage, the PN/PN Coupler restarts.

Device replacement with topology configuration
IO devices with this function can be replaced in a simple manner. The device name does not have to be assigned with the PG/PC.
The replacement IO device is assigned the device name by the IO controller and not by the PG/PC. The IO controller uses the configured topology and the neighborhood relationships determined by the IO devices for this purpose. All involved devices must support the LLDP protocol (Link Layer Discovery Protocol). The configured topology must match the actual topology.
IO devices that were already used in another configuration must be reset to factory settings before being reused.

Isochronous real-time communication

Isochronous real-time communication Synchronized transmission method for the cyclic exchange of IRT data between PROFINET devices. A reserved bandwidth within the send clock is available for IRT data. The reserved bandwidth ensures that the IRT data can be transmitted in time-synchronized intervals, unaffected by other high network loading (e.g. TCP/IP communication or additional real time communication).
A topology configuration is required for IRT.
Note IO controller as sync master with IRT communication
Operation of the IO controller as a sync master is recommended when configuring the IRT communication.
Otherwise, IO devices with IRT and RT configuration could fail as a result of sync master failure.

Shared Device

IO device that makes its data available to up to four IO controllers.
The PN/PN Coupler supports Shared Device at submodule level.
If the engineering system does not perform a plausibility check of shared device projects, note the following:
Ensure the consistency of the configurations. In particular, each module or submodule may only be assigned to one IO controller. Multiple assignment will result in an error. The module or submodule will only be available in the first IO controller.
If you reconfigure Shared Device configurations without the validity check mentioned above, you must commission the PN/PN Coupler again. This means you must download the projects of all involved IO controllers to the respective CPU again after reconfiguration and, if necessary, perform a POWER OFF/POWER ON of the PN/PN Coupler.
You can find more information:
In the STEP 7 online help
as of STEP 7 V14, in the SIMATIC PROFINET Function Manual (https://support.industry.siemens.com/cs/ww/en/view/49948856).

Note
For a Shared Device application, ensure that all IO controllers work with the same send clock. If IO controllers do not have the same send clock, the different send clock can result in communication relationships not being set up.
If you set up all IO controllers in one project, the same send clock is ensured. Set the same send clock when engineering in separate projects.

Module-internal Shared Input/Shared Output (MSI/MSO)
The module-internal Shared Input function enables an input module to make its input data available to up to four IO controllers. Each IO controller has read access to the same channels.
The module-internal Shared Output function enables an output module to be operated by up to four IO controllers. One IO controller has write access. Up to three additional IO controllers can have read access to the same channels.

Extended channel diagnostics

Function

The channel diagnostics provides information about channel faults of the PN/PN Coupler. Channel faults are mapped as channel diagnostics in IO diagnostic data records. You read the data record with the "RDREC" instruction.

Structure of the diagnostic data records
The data records supported by the PN/PN Coupler are based on the PROFINET IO standard - Application Layer Service Definition V2.3.
If necessary, you can purchase the standard from the PROFIBUS Nutzerorganisation (PROFIBUS user organization (https://www.profibus.com)).

Interrupts, error messages and diagnostics and system alarms 7.2 Diagnostics by user program

7.2.2

Interrupts
The IO device initiates interrupts following certain errors. The evaluation of the interrupt is dependent on the IO controller used.
The PN/PN Coupler supports the following interrupts:
Diagnostics interrupts
If the communication relation exists between the IO controller and the PN/PN Coupler, manufacturer-specific diagnostics of the PN/PN Coupler also become active as interrupts. The interrupts trigger the call of an OB 82 in a SIMATIC CPU.
Note Start information of the OB
Diagnostics on the PN/PN Coupler can already be pending, which will not be reported by a diagnostics interrupt. You must then explicitly read the diagnostic information with a diagnostic data record in the user program.
Use the start information of OB 86, for example, and the list of the diagnostics and configuration data records (https://support.industry.siemens.com/cs/ww/en/view/19289930) for PROFINET IO for this purpose.
Update interrupt (OB 56) for modules "RD READ STO" and "RD READ PUB":
You can optionally enable an update interrupt when configuring the "RD READ STO" and "RD READ PUB" modules: This indicates to the receiver that a new data record is available for reading in the buffer of the PN/PN Coupler.
The update interrupt is disabled by default. A new update interrupt can only be issued when the preceding interrupt has been acknowledged in the user program.
Note Module "RD READ PUB"
When new data records are received in quick succession, it is not ensured that a separate update interrupt will be issued for each received data record.
Maintenance alarms
The PN/PN Coupler supports diagnostics and the maintenance concept in PROFINET according to IEC 61158-6-10. The goal is to detect and remove potential problems as early as possible.
For the PN/PN Coupler, maintenance alarms signal to the user when a network component must be checked or replaced.

7.2.5

Diagnosis in Shared Device

Particularities for diagnostics and data validity:
The following conditions apply to diagnostics and data validity for the PN/PN Coupler as a Shared Device .
Diagnostics are signaled only to an IO controller that has slot 0 with subslot 1 or an interface.
The configuration-related diagnostics involve all slots:
� The diagnosis "Other network side is not configured or has failed" is generated if a partner slot is not available for any individual configured slot.
� The diagnosis "Different configuration of subnets X1 and X2" is generated is there is a difference in the module ID of the partner slot for at least one slot.
The diagnosis "Data validity DIA is set, but no input data is configured" covers only the slots that belong to the IO controller that has slot 0.
Shared Device conflict: invalid submodule assignment at slot n
� For MSI and MSO modules, submodules of the same length of output and input data must be used.
� For local MSO modules, the output submodule and at least 1 input submodule must be controlled by the IO controller assigned in each case.

7.2.6

STOP of the IO controller and recovery of the IO device

STOP of IO controller
The PN/PN Coupler indicates the STOP state of the IO controller of the other bus side using the optional "Data validity" diagnostics.

Diagnostics after STOP of the IO controller
If diagnostics are received from the IO device while the IO controller is in STOP state, the corresponding organization blocks are not initiated after startup of the IO controller. You must get an idea of the state of the IO device in OB 100. Evaluate the data status byte (DS) of the input modules in your user program.

Diagnostics after recovery of the IO device
Following recovery of an IO device, you must read data record E00CH with the "RDREC" instruction. This contains all the diagnostics data for the slots assigned to an IO controller in an IO device.

Electromagnetic compatibility (EMC) is the ability of an electrical installation to function satisfactorily in its electromagnetic environment without interfering with that environment.
Among other things, the PN/PN Coupler also meets the requirements of the EMC legislation for the European single market. The prerequisite for this is that the PN/PN Coupler complies with the requirements and guidelines relating to electrical configuration.

Response times

Response times The time that elapses between an IO controller writing to the process image outputs and when this data can be read in the process image of the second IO controller depends on the following: CPU cycle time of the two IO controllers Bus cycle time of the associated IO controller Duration for copying within the PN/PN Coupler (TCOPY) Total data length in bytes (input/output) The copying duration of the PN/PN Coupler depends on the data transmission rate used. It consists of the copy routine for the inputs and for the outputs. The following maximum values apply: TCOPY = 25 �s + nIN x 0.06 �s + nOUT x 0.03 �s + (nSUB-1) x 3.5 �s nIN: Number of bytes of inputs nOUT: Number of bytes of outputs nSUB: Number of submodules used
Influencing factors for the response times The following applies to time-critical applications: Divide the data among as few modules and submodules as possible. Do not use data record modules. Exchange as little data as possible via the PN/PN Coupler. Do not request diagnostic data from the IO controller. Do not activate the data validity display DIA. Do not activate the data validity diagnostics.

Compatibility

Replacing PN/PN Coupler V3.0 with PN/PN Coupler V4.0 If you replace PN/PN Coupler V3.0 with PN/PN Coupler V4.0, no reconfiguring or rewiring is necessary, except in the following cases: You used a SIMATIC memory card in the project. Because PN/PN Coupler V4.0 and higher no longer has a SIMATIC memory card, the BusAdapter acts as a memory card. In this case, you must provide the PN/PN Coupler with the device name, e.g. with STEP 7 TIA Portal or with PRONETA. You have used an angled 90� PROFINET connector and you want to use the following BusAdapters: � BusAdapter with RJ45 socket: Replace the angled PROFINET connector with the BusAdapter 2�RJ45 socket (for example with SIMATIC NET IE FC RJ45 Plug 180). � BusAdapter with FC connection: Connect the PROFINET cable directly.
Note New assembly You do not have to remove the PROFINET cables again for a new assembly.
The transmission rate of 10 Mbps for Ethernet services is not supported. You have configured the IRT operating mode with "Flexibility". You now need to re-
configure the PN/PN Coupler with the "IRT" operating mode for STEP 7 TIA Portal. Vendor-specific diagnostics: the User Structure Identifier (USI) is reduced from 4 bytes to
3 bytes.
PN/PN Coupler V4.0 with configuration for firmware version V3.0 If you are using a PN/PN-Coupler as of article number 6ES7 158-3AD10-0XA0 and firmware version V4.0 under configuration of a PN/PN Coupler with FW version V3.0 (compatibility mode), the PN/PN Coupler works in the module operating mode "IO Modules". The data validity of the coupled user data in this module operating mode is ensured by the provided user data flags of the PROFINET system.
Note Module operating mode for PN/PN Coupler with firmware version 3.0" The module operating mode "IO Modules" for the firmware version V3.0 uses the concept of closer data coupling. This means no additional data status byte (DS) is used for the input modules.

PN/PN coupler Hardware Installation and Operating Manual, 09/2019, A5E00717043-AH

Glossary

Autonegotiation
Configuration protocol in Fast Ethernet. Before the actual data transfer, the devices on the network agree on a transfer mode that each participating device can work with (100 Mbps or 10 Mbps, full-duplex or half-duplex).

Bus A common transfer route connecting all nodes and having two defined ends.

BusAdapter

Enables free selection of the connection technology and layout for the PROFINET fieldbus.

Cross-over cable
A cross-over cable is a four-wire or eight-wire twisted pair cable in which specific cable wires are swapped in one of the two RJ45 connectors. You can use a cross-over cable to connect two controllers directly with each other.

Data record routing
Forwarding of data records beyond subnet boundaries from a sender to receivers via a router.

Data status byte (for inputs only)
Users need the data status byte (DS) to check the validity of the coupled user data. An additional byte is added to all input modules; it can be evaluated in the user program.

Device name

Before an IO Device can be addressed by an IO Controller, it must have a device name. This procedure was selected for PROFINET because names are easier to handle than complex IP addresses.
Assignment of a device name for a specific IO Device can be compared with the setting of the PROFIBUS address for a DP slave.
An IO Device does not have a device name upon delivery. Only once a device name has been assigned using the PG/PC, can an IO Device be addressed by an IO Controller, e.g. for the transmission of configuring data (including the IP address) during start-up or for the exchange of useful data in cyclic mode.

Glossary

Device replacement without removable medium/programming device
IO Devices having this function can be replaced simply:
A removable medium (such as Micro Memory Card) with the stored device name is not required.
The device name does not have to be assigned using the programming device.
The replaced IO Device receives the device name from the IO Controller, not from the removable medium or from the programming device. For this purpose, the IO Controller uses the configured topology and the neighborhood relationships determined by the IO Devices. The configured setpoint topology must agree with the actual topology.

Diagnostics

Diagnostics is the detection, localization, classification, display and further evaluation of errors, faults, and messages.
Diagnostics provides monitoring functions that run automatically while the system is in operation. This increases the availability of systems by reducing setup times and downtimes.

Earth

The conductive earth whose electric potential can be set to zero at any point.

Electromagnetic compatibility (EMC)
Electromagnetic compatibility is understood as the ability of a piece of electrical equipment to function perfectly in a specified environment without impacting on its surroundings in an impermissible way.

Equipment, electrical
All components, power circuits or parts of power circuits that are normally to be found in one single enclosure.

Equipotential bonding
Electrical connection (equipotential bonding conductor) that brings the conductive parts of electrical equipment and other conductive parts to the same or approximately the same potential in order to prevent troublesome or dangerous voltages arising between these parts.

External lightning protection
External lightning protection is part of the lightning protection system and comprises an interception device, an arrester and a grounding system. In the event of a lightning strike, the external lightning protection serves to divert the lightning current safely to the ground.
Corresponds with lightning protection zone 0A and 0B.

Glossary

Fast Ethernet

Fast Ethernet describes the standard for transmitting data at 100 Mbps. This transfer technology uses the 100 Base-T standard for this.

Firmware update
Updating of firmware of interface module
After (compatible) function extensions or after improvements to performance, the interface module can be updated to the latest firmware version.

Ground

The ground refers to all the interconnected inactive parts of a piece of equipment that, even in the event of a fault, cannot pick up voltage that is dangerous to touch.

Grounding

Grounding means connecting an electrically conductive part to a grounding system by means of the ground electrode.

GSD file

The properties of a PROFINET device are described in a GSD file (General Station Descriptor), which contains all the information required for configuration.
As with PROFIBUS, you can link a PROFINET device in STEP 7 by means of a GSD file.
In PROFINET IO, the GSD file is always in XML format. The structure of the GSD file corresponds to ISO 15734, the worldwide standard for device descriptions.

HW Config

Part of STEP 7 for configuring hardware.

Isochronous real-time communication
Synchronized transmission method for the cyclic exchange of IRT data between PROFINET devices.
A reserved bandwidth is available within the send cycle for IRT IO data. The reserved bandwidth guarantees that IRT data can also be transferred at reserved, synchronized intervals while other, higher network loads are active (for example, TCP/IP communication, or additional real-time communication).

LAN

Local Area Network; interconnects multiple computers within a company. The geographical topology of a LAN is limited to the local premises and is only available to the operating company or institution.

Glossary

LLDP

LLDP (Link Layer Discovery Protocol) is a protocol that is used to detect the closest neighbors. It enables a device to send information about itself and to save information received from neighboring devices in the LLDP MIB. This information can be looked up via the SNMP. This information allows a network management system to determine the network topology.

MAC address

Each PROFINET device is assigned a worldwide unique device identifier in the factory. This 6-byte long device identifier is the MAC address.
The MAC address consists of:
3-byte manufacturer ID and
3-byte device ID (sequential number).
The MAC address is placed legibly on the front of the device e.g.: 08-00-06-6B-80-C0

MDI

In network connections it is normal for each device to be equipped with separate cable wires for transmitting and receiving. The network sockets (MDI) must be coupled in such a way that the transmit wire of one device lines up with the receive wire of the other device. If you use a cross-over cable, the wires are thereby interchanged (crossed) and communication is possible without additional devices.

MDI-X

The MDI-X connection type refers to a socket that is already internally crossed in the device. It is common in distribution devices, such as switches.

Parameter assignment
The term parameterization denotes the transfer of parameters from the IO Controller to the IO Device.

PELV

Protective Extra Low Voltage = extra low voltage with safe isolation that is grounded.

Power supply unit
A power supply unit supplies power to the field devices and the distributed process I/Os connected to them.

Prioritized startup
Prioritized startup denotes PROFINET functionality for accelerating the startup of IO Devices in a PROFINET IO system with RT and IRT communication. The function reduces the time that the correspondingly configured IO Devices require in order to return to the cyclic user data exchange in the following cases:
After the supply voltage has returned
After station recovery
After IO Devices have been activated

Process image

The process image is part of the IO Controller's system memory. The signal states of the input modules are transferred to the process-image inputs at the beginning of the cyclic program. At the end of the cyclic program, the process image of the outputs is transferred to the IO Controller as signal status.

PROFIBUS International
Technical committee dedicated to the definition and development of the PROFIBUS and PROFINET standard.

PROFINET

Within the context of Totally Integrated Automation (TIA), PROFINET is the systematic continuation of the following systems:
PROFIBUS DP, the established fieldbus
Industrial Ethernet, the communication bus for the cell level
Experiences from both systems have been and are being integrated in PROFINET.
PROFINET is an Ethernet-based automation standard of PROFIBUS International (previously PROFIBUS User Organization e.V.), and defines a multi-vendor communication, automation, and engineering model. PROFINET has been part of IEC 61158 since 2003.
See PROFIBUS International

PROFINET components
A PROFINET component includes all data of the hardware configuration, the parameters of the modules, and the associated user program. The PROFINET component comprises the following elements:
Technological function
The (optional) technological (software) function includes the interface to other PROFINET components as interconnectable inputs and outputs.
Device
The device represents the physical automation device or field device, including the IO, sensors and actuators, mechanical system, and device firmware.

PROFINET device
A PROFINET device always has at least one Industrial Ethernet port. Additionally, a PROFINET device can have a PROFIBUS connection: as master with proxy functions In exceptions, a PROFINET device can also have a several PROFIBUS connections (for example CP 5614).

PROFINET IO Controller
Device by means of which connected IO Devices are addressed. In other words: The IO Controller exchanges input and output signals with the assigned field devices. The IO Controller is often the controller in which the automation program is executed.

PROFINET IO

Within the context of PROFINET, PROFINET IO is a communication concept for implementing modular, distributed applications.
PROFINET IO allows you to create automation solutions familiar from PROFIBUS.
Implementation of PROFINET IO is carried out on the one hand via the PROFINET standard for automation devices and on the other by using the engineering tool STEP 7.
This means that you have the same application layer in STEP 7 � regardless of whether you configure PROFINET devices or PROFIBUS devices The programming of your user program is identical for PROFINET IO and PROFIBUS DP when you use the blocks and system status lists expanded for PROFINET IO.

PROFINET IO Device
Distributed field device which is assigned to one of the IO Controllers (e.g. remote IO, valve terminals, frequency converter, switches).

Reference potential Potential that is used to view and/or measure voltages for each circuit involved.

SELV

Safety extra low voltage (SELV) is voltage 30 V AC/60 V DC that is generated via a safety transformer or accumulator.

SNMP

SNMP (Simple Network Management Protocol) is the standardized protocol, for diagnosing and also configuring the Ethernet network infrastructure.
In the office setting and in automation engineering, devices from many different manufacturers support SNMP on the Ethernet.
SNMP-based applications can be operated on the same network in parallel to applications with PROFINET.
The scope of the supported functions differs depending on the device type. For example, a switch has more functions than a CP 1616.

Switch

PROFIBUS is a linear network. The communication nodes are connected with one another by means of a passive line - the bus.
By contrast, the Industrial Ethernet consists of point-to-point connections: each communication node is directly connected to exactly one communication node.
If a communication node is connected with several communication nodes, this communication node is connected to the port of an active network component - the switch. Additional communication nodes (including switches) can now be connected to the other ports of the switch. The connection between a communication node and the switch remains a point-to-point connection.
A switch also has the task of regenerating and distributing received signals. The switch "learns" the Ethernet address(es) of a connected PROFINET device or other switches and only forwards signals, which are destined for the connected PROFINET device or the connected switch.
A switch has a specific number of ports. You connect at most one PROFINET device or additional switch to each port.

TN-S system

In a TN-S system, the neutral conductor (N) and protective conductor (PE) are wire with separate insulation. The neutral conductor is connected to the grounded protective conductor at a central point, and only there. The protective conductor can be grounded any number of times.

Transmission rate The transmission rate specifies the number of bits transmitted per second.

User data flag

Each IO module is assigned a value in the input or output data message; this value provides a statement on the quality of this user datum. For example, outputs of a specific module can be switched off by means of this without affecting other modules.
