5. Operation Using I/O Signals
5. Operation Using I/O Signals
This chapter explains the wiring/connection and operation timings you should know to perform positioning
operation using a PLC and I/O signals.
For PIO pattern, two types are available. The movement complete signals have different meanings in each type,
so select an appropriate type according to your specific application.
* Solenoid valve mode 0 is set at the shipment.
5.1 Interface Circuit
The standard interface circuit conforms to the NPN specification, but the PNP specification type is also available
as an option.
To simplify wiring, a common power line is used for both the NPN specification and PNP specification.
Accordingly you need not reverse the power connections when using the PNP specification.
