27.3 User Device
This chapter describes the user device.
Input (X)
This device provides the CPU module with commands and/or data using an external device, such as pushbutton, transfer
switch, limit switch, and digital switch.
Concept of input
Assume that one virtual relay Xn is incorporated into the CPU module for each input point. In the program, a normally open
contact and normally closed contact for the Xn are used.
Also, the input can be used as a target re-flesh (CPU module side) device of the remote input (RX), such as the CC-Link IE
Field Network.
Output (Y)
This device outputs the control results of the program to various devices, such as external signal light/digital HMI/
electromagnetic switch (contactor)/solenoid.
