•LED Status — When the LED is illuminated the proper ON state signal is received at the input or at the output point.

•Removable Lockable Terminals — Terminals are easily removable for I/O module replacement and are lockable so they will not

vibrate loose. Terminals are available in screw type, cage clamp and insulation displacement.

•Terminal Identification — Each terminal is marked for ease of wiring and troubleshooting.

•Isolation — Each module is optically isolated between the field I/O and the backplane communication.

•Securing Tabs — Each I/O module has a locking mechanism to secure it to the DIN rail.

•Barrier Type Terminals — Each terminal has a barrier to minimize shorting of field wiring.

Discrete Input Modules

The IT. D77A Input modules have the following common feature:

•Adjustable Debounce — Each point has adjustable debounce from 1 to 65 ms.

•Sink/source — Each DC input module has back-to-back LEDs in the optical isolating circuit that can accept sinking or sourcing

signals.

Discrete Output Modules

The IT. D77A I/O Output modules have the following common features:

•Configurable Safe State — Each output point has a loss of communication safe state setting.

•Configurable Power ON State — Each output point has a power-up setting.

Catalog Numbering System

Catalog numbers have three or five groups of characters, depending on the kind of module the catalog number represents. The

catalog numbering system used for IT. D77A I/O modules is illustrated as follows:

For discrete digital and analog I/O, the first four positions in the first group indicate the product family. The next two places in the

second group indicate the I/O type. The third group uses one or two places to indicate the number of points in the module. The last

group is used only for combination modules.

Dimensional Data

Figure 2 illustrates the dimensional data of the IT. D77A I/O modules.

Figure 2: Module Physical Dimensions, mm [in]

a) Single Wide Module

b) Double Wide Module

Note: Ventilation requirements necessitate a minimum of 50 mm (2 in) on the top and bottom of each module and to each side of a

module grouping.

Power Requirements

The current draw for the IT. D77A I/O modules can be found in the module specification table for each specific module type. When

specifying the 24 volt DC power supply, the power rating must support the sum of all the modules’ current draw added to the system

power requirements.

For more information on the sizing of power supplies, refer to the IT. QCPort System Install and Planning Guide (Publication No.

MN05001002E).

Surge Suppression

IT. D77A Discrete I/O output modules have built-in surge suppression (snubbers) to reduce the effects of transient voltages. When

connecting output devices that have inductive loads (e.g., solenoids, relays, motor starters, etc.) additional surge suppression is

recommended and should be added across the load. The addition of customer-supplied surge suppression for inductive loads

prolongs the D77A output life.

Theory of Operation

The IT. D77A I/O system consists of a collection of input and output modules connected together by QCPort to a network adapter. The

network adapter connects to the industrial network where the controller usually is a PLC or DCS. The input modules collect digital or

linear signals from sensors (limit switches, proximity sensors, temperature transmitters, etc.) and deliver these data to the control

device. In the control device, input data values are placed in data registers. Based on the input data, the control algorithm manipulates

values in the output registers. With each scan of the network, the input and output data registers are updated. With this update, the

output modules have their digital or linear data changed to reflect the control algorithm found in the control device software. The

output devices (solenoid valves, motor starters, temperature gauges, etc.) effect changes to the machinery being controlled.

Out-of-box Default Operation

When the IT. D77A I/O modules are properly installed and each has a properly configured Group ID (address), no additional

configuration is needed for standard operation. To customize the configuration, refer to Configuration on page 34. After customizing

the configuration, the system can be restored to the default out-of-box configuration without a software tool such as CH Studio by

following these steps.

1. Using a screwdriver, rotate the Group ID Switch from the “0” position to the “1” position.

2. Repeat this action five times.

The status LED rapid flashes, signaling that the system is reset to the out-of-box default settings.

Typical Application

Figure 16 illustrates a typical D77A I/O module application this is integrated with a number of IT. starters with QSNAPs. In this

example, a D77A I/O is part of a larger system where motor control and I/O are required within a single panel. On the same QCPort

connection, both the I/O and the motor control are connected to a single network Adapter. The network adapter then represents the

D77A I/O and motor control as remote I/O, allowing for control and monitoring of the QCPort devices.

I/O Function

Discrete Input Modules

Figure 17 illustrates the basic signal processing operation. When a signal is present at the input point, the module responds with the

following sequence:

1. Optical Isolation — Optical isolation protects the I/O circuits and communication circuits from possible damage due to

transients and over-voltage.

2. Debounce Logic/Control — A debounce circuit and software limits the effects of transients and electrical noise by requiring the

input to be true for a certain period of time before the logic acknowledges a true signal. Once a true signal is achieved, the logic

turns on the LED.

3. QCPort Com./Logic — The logic updates the QCPort communication on a regular, scheduled basis as to the status of the input

point.

Figure 17: Discrete Input Module Operation

Discrete Output Modules

Figure 18 illustrates the basic logic processing operation. When the processor activates an output point, the module responds with

the following sequence:

1. QCPort Com./Logic — QCPort communication updates the logic circuit on a regular, scheduled basis as to the status of the

output points.

2. Optical Isolation — Optical isolation protects the I/O circuits and communication circuits from possible damage due to

transients and over-voltage. Once an active signal is transmitted to the optical isolation circuit, the LED is forward-biased.

3. Output Drivers — The driver activates the output point.

Analog Input Modules

Figure 20 illustrates the basic signal processing operation. Analog signals from four separate channels are received by a multiplexer

(MUX). The MUX sequentially transfers this data to an analog-to-digital converter (ADC). The ADC measures the analog signal and

converts it to a digital value. This digital value is presented to the controller’s central processes unit (CPU). This data is then presented

to the QCPort for external processing.

Figure 20: Analog Input Module Operation

Analog input signal delays are associated with multiplexer switching, channel updating and channel reconfiguration. These delays are

all influenced by analog input filter frequency selection.

they can be daisy chained together using QCPort Interconnect cables. There are standard sizes for the QCPort Interconnect cables.

These sizes are listed in the “Renewal Parts” portion of “Troubleshooting and Maintenance.”

Note: The maximum current allowed through a QCPort interconnect cable is 1 Amp. The maximum number of modules that may be

daisy chained together using QCPort interconnect cables is calculated by adding the current rating of each device and keeping

the total less than 1 Amp.

When making this interconnect, refer to the IT. QCPort System Install and Planning Guide (Publication No. MN05001002E) for the

recommended cable and connections.

AC Inputs

AC power is typically used to energize loads related to machinery function such as solenoid valves and motor starters. The same AC

power source is often used as signal power for inputs as illustrated in Figure 35. The input devices to which AC inputs are wired are

typically two-lead devices like push buttons, limit switches and selector switches. One side of the input device is wired to an AC power

source while the other is wired to the input terminal. Another input terminal is wired to a grounded neutral wire. Refer to AC Output

Analog Inputs

Analog signals are typically used to transmit or indicate linear data like temperature, pressure or flow, as illustrated in Figure 37. The

analog input devices to which analog inputs are wired are typically current loop or voltage range devices like 4-20 mA transmitters or

0-10V transmitters. Refer to Analog Input Module Specifications on page 10 for module details.

Note: Ground the shield on one end only. It is recommended to limit the cable impedance by keeping the cable length as short as

possible. Limiting the distance from ground to the shield is also recommended. The recommended cable is a BeldenTM 8761 or

equivalent.

Note: When an input channel in not used, jumper from V to C eliminating noise from causing erroneous readings for that channel.

Explanation of LED Duty Cycle States

Table 30: Explanation of LED Duty Cycle States

Observation Possible Cause/Corrective Action

The input LED will not illuminate. Verify that the module is powered; the LED is controlled by the micro controller

in the device.

The power for the input itself may not be applied. Verify that there is a valid

signal on the input point.

The screws on the terminal may be loose; tighten the screws.

Replace the device.

The output LED is illuminated but the output is not on. Check that the switch closes on the output using a multi meter.

The screws on the terminal may be loose; tighten the screws.

Replace the device.

The status LED has a “fast blink” while all other device’s

status LEDs are “mostly on.” See Table 26 Status LED. The “fast blink” device may have the same Group ID as another device. Verify

that all devices have unique Group IDs.

The “fast blink” device was not accepted into the scan list. Reasons include it

was replaced and the device is not the same as the original device (parameters

are different or the product is different).

An out-of-box device was inserted into an actively scanning QCPort; power will

need to be cycled on QCPort to be accepted.

While On-Line with CH Studio the I/O Module disappears. It may be that the controller is not allowing enough time for the CH Studio

messages and the connection between CH Studio and the Network Adapter is

timing out. You may have to take the system controller off-line to continue or

add an interscan delay to the industrial network scan.

While looking at the I/O Module it is noticed that the status

LED is solid on. If no other LED’s are on it is possible the I/O Module was placed into a firmware

download mode, cycle power to the I/O Module and see if the LED behaves

properly.

The module may have corrupt memory or damage to the circuit board and the

module will need to be replaced.

Table 31: Status LED

Communication Hints

Table 32: Communication Hints

Status LED Description Explanation

Mostly Off Offline Everything is OK with in the I/O Module and the I/O Module is not being scanned.

Check that the Network Adapter is commanded to scan QCPort. This is generally done by setting bit 0 of byte

0, for channel A, in the output assembly.

Mostly On Online Everything is OK with in the I/O Module and the I/O Module is being scanned.

50% Faulted Internal memory fault (cycle power).

Verify that there are not any duplicate Group ID’s (address). Check that the address is unique for the QCPort

system.

The Group ID was changed and a reset is required.

Buss fault. All the devices on the QCPort will have the same status LED behavior. A buss fault is caused by an

open or QCPort shorted buss.

Rapid Flash Unacquired The I/O Module has not been discovered/acquired by the Network Adapter, verify that the node ID is set

correctly for the system.

The Network Adapter has not auto configured the QCPort system. In this case all the I/O Module’s will have

the same behavior of the status LED. Perform an auto configuration.

CH Studio is identifying that device. When the device is highlighted in CH Studio this is a way to identify in

the field which device is being highlighted. Remove the highlight from CH Studio and verify that the Rapid

Flash disappears.

Solid On It is possible the I/O Module is in firmware download mode, cycle power to exit that mode. If the LED stays

solid On after the power cycle, it is possible that the I/O Module has in internal failure and will need to be

replaced.

Off No Power The I/O Module is not powered or a memory fault in NV RAM has occurred that will require the I/O Module to

be replaced.

Problem Solution

Are all the QCPort devices

connected to one Network

Gateway are not

communicating? Are all the

Status LED’s either Rapid

Flash or 50% On

Check the Network Adapter, is the ST LED Green? – If the LED is green, then perform an auto configuration of

the Network Adapter and see if the problem goes away.

There may be a damaged I/O Module or a shorted QCPort communication wire that is prohibiting QCPort

communications. Remove all the I/O Modules from the QCPort system.

Unplug the Network Adapter from the industrial network.

Cycle power to the Network Adapter.

One by one plug the I/O Modules back in and verify that the status LED is mostly off as they are plugged back in.

When the I/O Module the causes the system to fail is plugged in, the I/O Module’s status LED will rapid flash or

50% flash only.

Remove the I/O Module and check the QCPort connections for shorted or damaged wires or connections.

When all the I/O Modules are online, plug the Network Adapter into the industrial Network.

It is possible that the terminating resistors are damaged, replace the terminating resistors.

Is there a single I/O Module

in the system that is not

communicating?

The problem may be that the I/O Module has a fixable internal communication failure. Perform a reset by

toggling the rotary switch from 0 to 1 five times, reset the rotary switch to the correct group ID (address).

It is also possible the Group ID rotary switch was changed after auto configuration. Check the rotary switch and

verify that they are in the correct position for that address. Physically move the rotary switch from one position

to another to verify that it is in the correct position (there will be a “snap” when it reaches the next state).

Unplug and replug the device and check that the problem disappears.

It is possible that the communication connections are damaged or unplugged.

It is possible that the terminating resistors are damaged, replace the terminating resistors.

During auto configuration

the Network Adapter will not

detect any of the I/O

Modules.

Check the status LEDs on the I/O Module units, if the LEDs are rapid flashing or 50% On refer to the above

problem for a solution.

If the status LEDs on the I/O Module units are all slow flashing, the Network Adapter has already connected to

the I/O Module units and the problem is that the CH Studio software is not displaying the I/O Module units. This

can be because the scanner is not allowing CH Studio to send long messages.

The Network Adapter cannot perform an auto configuration if the system controller is scanning the Network

Adapter. Disconnect the Network Adapter from the industrial network and reattempt the auto configuration.

Size Description

1 byte This parameter specifies the address used by a Master for data transfers in the Master/Slave Data Protocol.

The default value must be 0x00 (unconfigured), requiring a Master to set this value prior to using the Master/

Slave Data Protocol.

Size Description

2 bytes This parameter specifies the destination Node ID to be used by a device in either the Simple System or Wire

Replacer Data Protocols. The MSB indicates the Group ID; the LSB indicates the Member ID.

An Initial Value of 0x0000 indicates an unconfigured state. In this state, a device assumes a current value equal

to its Group ID and a Member ID of 0x00. This results in its Production Data being targeted at all members of its

Group.

Size Description

32 bytes This parameter specifies the 32-character ASCII string ID tag assigned to a device, pre-assigned at the factory

but can be set by the user.

Size Description

2 bytes This parameter specifies the rate, in milliseconds, at which a producing device generates a Data Protocol

message in either Simple System or Wire Replacer mode.

A value of 0 disables this timer.

Size Description

2 bytes This parameter is the value to which the consumption timer is set whenever there is a set of the current value of

any parameter on the consumption list.

Expiration of this interval causes the module to execute communications loss behavior.

A value of 0 disables this timer.

Size Description

92 bytes This read-only list specifies the n QCPort Parameters that a device supports.

Size Description

2 bytes This 2n-byte read-only list specifies the n QCPort Parameters included in a device’s QCPort Data Parameter

0x0001, Production Data.

Setting Parameter Attribute 0x09, “Production List Member,” to TRUE, designates a Parameter’s membership in

this list. Only Parameters supporting Attribute 0x09 are eligible for inclusion in this list.

Ordering of Parameter IDs in the Production List is based first on Parameter data size and then sequentially

within Parameters of like size. For example, all Parameters with an even number of bytes would appear first

sequentially, followed by Parameters with an odd number of bytes.

Size Description

2 bytes This 2n-byte read-only list specifies the n QCPort Parameters included in a device’s QCPort Data Parameter

0x0002, Consumption Data.

Setting Parameter Attribute 0x0A, “Consumption List Member,” to TRUE, designates a Parameter’s membership

in this list. Only Parameters supporting Attribute 0x0A are eligible for inclusion in this list.

Ordering of Parameter IDs in the Consumption List is based first on Parameter data size and then sequentially

within Parameters of like size. For example, Parameters with an even number of bytes would appear first

sequentially, followed by Parameters with an odd number of bytes.

Size Description

n bytes This is a list of languages supported in the product. It consists of a list of bytes, each representing a different

language.

0x00 — English

0x01 — Spanish

0x02 — French

0x03 — German

Size Description

1 byte Holds the currently selected language from the list in parameter 800E.

Size Description

4 bytes The purpose of this parameter is to provide a method for tools to access a QCPort node in a non-conflicting

manner.

This parameter consists of a field of 2 UNITs organized as follows:

Byte

Node ID Low byte

Node ID High byte

Lockout Time in tenths of seconds Low byte

Lockout Time in tenths of seconds High byte

If the above 4 bytes are 0, anyone can write to this parameter. This parameter is cleared by the Clear Semaphore

command that can be sent by anyone. If all 4 bytes are not 0 and a write (other than a clear) to this parameter is

attempted, an error message will be returned. The parameter will be cleared when the timer counts down to 0.

If the node ID field is 0, all set parameters to the node will be accepted. If the node ID field is not 0, set parameter

commands to the node will only be accepted from the device having the same node ID as that contained in this

parameter. Note that if the node ID is set to zero at the same time that a non-zero value is loaded to the timer, the

timer will not decrement.

Size Description

The n bytes Used in discrete output modules. Each bit of this parameter is associated with an output bit and defines the

behavior of that output upon detection of communications loss.

If a bit in this parameter is 1, the output bit holds the last state.

If a bit is 0, the output bit is determined by the initial value.

Size Description

The n bytes Used with discrete input devices. This parameter consists of a series of UNITs, two bytes for each discrete input

and holds the debounce time for that input.

Size Description

2 bytes This parameter may be used with modules having a hardware node ID switch and represents the actual setting

of that switch.

Size Description

n Bytes Determines the communication loss behavior of the output module.

0 = Hold last state

1 = Use Communication Loss Value

2 = Use Initial Value

Size Description

Word Value that the output channel will go to if selected using the communication loss behavior.
