Hello,
I have a conveyor belt system which is soon to have two PLCs able to control it. At present it is only designed to be controlled by one PLC.
I need to design a circuit that allows switching for a set of 11 24V in and 11 24V out circuits on a single switch. The aim is simply to use 1 switch to select which PLC's I/O is fed to the machine.
The machine in use is this: http://www.bytronic.net/html/ict_3.html
Can anyone give me starting suggestions on the best way to approach this switching problem? A 22-pole switch seems a little bit inelegant and unlikely!
