Preface
Security information
Siemens provides products and solutions with industrial security functions that support the secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is necessary to implement � and continuously maintain � a holistic, state-of-the-art industrial security concept. Siemens' products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems, machines and networks. Such systems, machines and components should only be connected to an enterprise network or the internet if and to the extent such a connection is necessary and only when appropriate security measures (e.g. firewalls and/or network segmentation) are in place.
For additional information on industrial security measures that can be implemented, please visit (http://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more secure. Siemens strongly recommends that product updates are applied as soon as they are available and that the latest product versions are used. Use of product versions that are no longer supported, and failure to apply the latest updates may increase customers' exposure to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS Feed visit (http://www.siemens.com/industrialsecurity).

SINETPLAN

SINETPLAN, the Siemens Network Planner, supports you in planning automation systems and networks based on PROFINET. The tool facilitates professional and predictive dimensioning of your PROFINET installation as early as in the planning stage. In addition, SINETPLAN supports you during network optimization and helps you to exploit network resources optimally and to plan reserves. This helps to prevent problems in commissioning or failures during productive operation even in advance of a planned operation. This increases the availability of the production plant and helps improve operational safety.
The advantages at a glance
Network optimization thanks to port-specific calculation of the network load
Increased production availability thanks to online scan and verification of existing systems
Transparency before commissioning through importing and simulation of existing STEP 7 projects
Efficiency through securing existing investments in the long term and optimal exploitation of resources
You can find SINETPLAN on the Internet (https://www.siemens.com/sinetplan).

Connecting 3.1 Wiring and block diagram
Wire-break detection
When wire-break detection is configured the module requires a low quiescent current at the digital input in case of "0" signal for the monitoring. The parallel connection of a resistor with 25 k to 45 k is required in order that this quiescent current can flow when mechanical transducer contacts are open. If wire-break detection is disabled in the configuration, no parallel connection of the resistor is required. If wire-break detection is configured, connect a resistor with 25 k to 45 k parallel to each mechanical transducer contact.

Parameters

Parameters for DI 16x24VDC ST
Specify the module properties with the various parameters in the course of your STEP 7 configuration. The following table lists the configurable parameters. The effective range of the configurable parameters depends on the type of configuration.
The following configurations are possible:
Central operation with an ET 200SP CPU
Distributed operation on PROFINET IO in an ET 200SP system
Distributed operation with PROFIBUS DP in an ET 200SP system
When assigning parameters in the user program, use the "WRREC" instruction to transfer the parameters to the module using the data records; refer to section Parameter assignment and structure of parameter data record (Page 28).

Channel activated
Determines whether a channel is activated or deactivated.

Input delay

This parameter can be used to suppress signal interference. Changes to the signal are only detected if they are constantly pending longer than the set input delay time.

Potential group
A potential group consists of a group of directly adjacent I/O modules within an ET 200SP station, which are supplied via a common supply voltage.
A potential group begins with a light-colored BaseUnit through which the required voltage is supplied for all modules of the potential group. The light-colored BaseUnit interrupts the three self-assembling voltage buses P1, P2 and AUX to the left neighbor.
All additional I/O modules of this potential group are plugged into dark-colored BaseUnits. You take the potential of the self-assembling voltage buses P1, P2 and AUX from the left neighbor.
A potential group ends with the dark-colored BaseUnit, which follows a light-colored BaseUnit or server module in the station configuration.

Evaluating the value status
An additional two bytes are allocated in the input address space if you enable the value status for the digital module. Bits 0 to 15 in these bytes are assigned to a channel. They provide information about the validity of the digital value.
Bit = 1: No fault is present on the channel.
Bit = 0: Channel is deactivated or there is a fault on the module.
If a fault occurs on a channel with this module, the value status for all channels is 0.

Parameter data record

A.1

Parameter assignment and structure of parameter data record
The data record of the module has an identical structure, regardless of whether you configure the module with PROFIBUS DP or PROFINET IO. With data record 128, you can reconfigure the module in your user program regardless of your programming. This means that you can use all the functions of the module even if you configured it via PROFIBUSGSD.

Parameter assignment in the user program
The module parameters can be re-assigned in RUN (for example, the input delay of selected channels can be edited in RUN without having an effect on the other channels).

Changing parameters in RUN
The "WRREC" instruction is used to transfer the parameters to the module using data record 128. The parameters set in STEP 7 are not changed in the CPU, which means that the parameters set in STEP 7 will be valid again after a restart.

Output parameter STATUS
If errors occur when transferring parameters with the "WRREC" instruction, the module continues operation with the previous parameter assignment. The STATUS output parameter contains a corresponding error code.
You will find a description of the "WRREC" instruction and the error codes in the STEP 7 online help.

Error transferring the data record
The module always checks all the values of the transferred data record. Only if all the values were transferred without errors does the module apply the values from the data record.
The WRREC instruction for writing data records returns corresponding error codes when errors occur in the STATUS parameter, see also the description of the "STATUS" parameter in the STEP 7 online help).
The following table shows the module-specific error codes and their meaning for the parameter data record 128.

Meaning

Solution

Number of the data record unknown.

Enter a valid number for the data record.

Length of the data record incorrect. Enter a valid value for the data record length.

Slot invalid or cannot be accessed. � Check the station whether the module is plugged or drawn.

� Check the assigned values for the parameters of the WRREC instruction.

Wrong version or error in the header information.
Invalid coding for input filter time.

Correct the version, length and number of parameter blocks.
Check the parameters of the module.
