1. Determine the MULTIPLE I/O TERMINAL I/O specifications.
Each Communication Unit for the MULTIPLE I/O TERMINAL can be
connected to a combined total of 128 input and output bytes (64 words) max.
(This figure does not include the 2 words of the input area allocated to the I/O
Unit interface status.)
In this example, the following configuration will be used:
•
Inputs:
16 digital inputs (2 words)
•
Outputs:
16 digital outputs (2 words)
•
Analog Input:
8 inputs (8 words)
•
Analog Output:
4 outputs(4 words)
2. Select the I/O Units.
•
PRT1-COM Communication Unit:
1 Unit
•
GT1-ID16 Transistor Input Unit, with terminal block:
1 Unit
•
GT1-OD16MX Transistor Output Unit, with connector:
1 Unit
•
GT1-AD08MX Analog Input Unit, 8 inputs:
1 Unit
•
GT1-DA04MX Analog Output Unit: 4 outputs:
1 Unit
3. Check the specifications.
•
Check that the total I/O Unit interface current consumption is less than
0.3 A. In this example, the total is calculated as follows:
Transistor Input Unit (35 mA) + Transistor Output Unit (35 mA) + Analog
Input Unit (50 mA) + Analog Output Unit (50mA)
=170 mA
4. Mount and connect the Communication Unit and I/O Units.

Connecting I/O Unit Connecting Cable
To connect each pair of Units, connect I/O Unit interface communications
connector 2 on the Unit closer to the Communication Unit to I/O Unit
interface communications connector 1 on the Unit closer to the end Unit.
