ACE as inputs/outputs: Mirror function by remote I/O copying
The ACE transmits the states of its inputs to the outputs of a remote ACE and the other way round.
The program is the same in each ACE .
For this operation you must have 2 ACE PLC with a free serial port, RS232 or RS485.
You must link each ACE by the serial port:
|RX to TX
TX to RX
GND to GND
Make sure the grounds are tied together and RX and TX are inverted
Upload Mirror-Mode-Between-2-Ace-PLCs program to each ACE PLC and run it. This program is an example for ACE-3090.
Then move inputs of one of them and you’ll see the inputs reflected on the other device’s outputs.
You have to change the tag names (inputs/outputs) depending of you ACE version.
That’s all !
