I am looking for a tool to make I/O distribution in a PLC of around 1000 I/Os. I have a lot of redundant signals (2oo3, 2oo2) and I have to make a consistent distribution in the modules and racks considering some criteria: different channels of redundant signals in different racks, etc. Normally I have done this manually but I wonder if there is a tool to do this much faster and without mistakes.
Builders from manufacturers, like TIA portal from Siemens or IAB from Rockwell, are of course very product oriented, they are a great help to select the right hardware, as far as I know they are not able to distribute redundant I/Os.
Anybody knows if a tool like this is available?
