Rockwell Automation 20-XCOMM-IO-OPT1 User Manual

I/O Board Option 20-XCOMM-IO-OPT1

Installation Instructions

These Installation Instructions are provided with the I/O Board option for use with the External Comms Kit 20XCOMM-DC-BASE. This document explains how to install the I/O board into the kit, and provides board specifications and I/O wiring details.

This I/O Board option provides additional I/O (6 DC inputs and 2 relay outputs) for the network — not the drive.

Compatability

To use the I/O board, the installed communication adapter must be the following hardware series and firmware revision release or higher:

Communication Adapter

20-COMM-E EtherNet/IP Series B v3.001

20-COMM-C ControlNet (coax) Series B v2.001

20-COMM-Q ControlNet (fiber) Series A v2.001

20-COMM-D DeviceNet Series B v2.001

Important: Even though the 20-COMM-B BACnet MS/TP

Required Hardware (or higher)

and 20-COMM-M Modbus/TCP adapters can be operated in a 20-XCOMM-DC-BASE Comms Kit, the adapter’s limitations cannot support the I/O board option.

Required Firmware (or higher)

Installing the I/O Board

1. Remove J1, 12-position Terminal Block Connector.

2. Insert the black bezel into the base of the light pipe

(Figure 1

3. Carefully align the light pipe assembly over the 8 LED

indicators and snap it into the slots on the board.

4. Set JMP 1 Fault Action Jumper for either Fault

Configurable (FLT position, pins 1-2) or Hold Last State (HLS position, pins 2-3). See Figure 1

5. Carefully align the I/O board socket onto the mating plug

of the Comm Kit’s power supply board while placing the I/O board onto the three standoffs.

6. Fasten the I/O board to the standoffs using the three

screws supplied with the I/O board.

7. Reinstall J1, 12-position Terminal Block Connector.

8. Fasten the enclosure cover onto the Comm Kit’s base

using the two screws in the cover.

Configuring the 20-COMM-* Adapter for I/O

When the optional I/O board is installed and the Comms Kit is mounted and connected, configure the I/O inputs and outputs. Refer to the communication adapter User Manual for complete details.

I/O Board LED Indicators

LED Name State Description

IN1 (Input 1) Green Normal operation, Input 1 ON

Off Normal operation, Input 1 OFF

Solid Red

Flashing Red

Orange OPT1 self-diagnostics failure

IN2 (Input 2) IN3 (Input 3) IN4 (Input 4) IN5 (Input 5) IN6 (Input 6)

OUT1 (Output 1) OUT2 (Output 2)

Green

Off

Green Output * ON

Off Output * OFF

Communication with the 20-COMM-* adapter has not been established.

Possible Reasons: Wrong adapter/series/ firmware (see table above), or bad connection.

Fault - 20-COMM-* adapter has experienced an Idle or Comm fault, and the I/O board is taking its configured fault action for the outputs.

Possible Reasons: Controller in Stop mode or powered down, DPI connector disconnected from drive or drive powered down, or network connector disconnected from 20-COMM-* adapter.

Input * ON

Input * OFF

(1)

These LEDs will indicate input status when the IN1 LED is in normal operation (Green or Off) and communicating with the Comm adapter. If the IN1 LED indicates a problem (Solid Red, Flashing Red or Orange), these LEDs will be turned Off and will not indicate input status.

I/O Board Specifications

Inputs

Number of Inputs 6 (single common)

Input Voltage Type 24 VDC source load

Maximum Input Voltage 27 VDC

Maximum Input Current 8 mA (each input)

Guaranteed ON-State Voltage 10 - 27 VDC (3 mA minimum)

Guaranteed OFF-State Voltage 0 - 5 VDC (2 mA maximum)

Reverse Polarity Protected -30 VDC

Response Time 25 ms + network update time

The I/O board is NOT designed for fast I/O response times. Do NOT use with input devices that will transition (OFF J ON J OFF) faster than the response time. Potential input devices include auxiliary contact inputs from relays or overloads, pushbuttons, etc.

Outputs

Number of Outputs 2 relay outputs (individually isolated)

1 - Form C contacts 1 - Form A (NO) contact

Maximum Output Contact Voltage

Maximum Output Contact Current

Expected Contact Life 1,000,000 cycles resistive at < 0.5A

Response Time 25 ms + network update time

The I/O board is NOT designed for fast I/O response times. Do NOT use with output devices that need to transition (OFF J ON J OFF) faster than the response time. Potential output devices include pilot lights or a contact closure reset to another hardware device.
