■Example of interlock using devices other than X and Y
An example of sending data in W0 to W3 of the master station (station No.0) to W1000 to W1003 of the local station (station
No.1) is shown below. This is a method used when X and Y cannot be used as interlock devices. (B0 and B1000 are used for
a handshake to the CPU module.)
