1.1 ID settings
Parallel I/O board IDs (1 to 4) are automatically allocated from the board connection position (in the option
slot number order).
The option slot numbers are shown on the option slots of the controller main body in the order like "upper left
→
lower left
→
upper right
→
lower right".
The parallel I/O board IDs can be set using the parameters as well. However, when the board has the standard
specifications, the ID is always "1".
ID General-purpose I/O Dedicated I/O
1
Standard specifications DI20-DI37 / DO20-DO27 Provided
*1
Expanded specifications DI10-DI37 / DO10-DO27 None
2 DI40-DI67 / DO30-DO47 None
3 DI70-DI117 / DO50-DO67 None
4 DI120-DI147 / DO70-DO107 None
*1 To enable the dedicated input, it is necessary to short-circuit CHK1 (pin number 4) and CHK2 (pin number 40) of the I/O.
NOTE
•Standard specifications/expanded specifications are determined at shipment.
•Only one standard specification board can be used.
•When changing the ID, it is necessary to turn off the controller power, and then turn it on again.
•If the ID setting is mismatched, all parallel I/O board IDs are initialized.
1.2 Power supply
When using the I/O interface, it is necessary to connect an external 24 V power supply.
Perform the wiring of the power connector of the parallel I/O board, and then connect the 24 V power supply.
