Hi there, this is not so easy as you may think. I suggest you download PLTrend, there you can select all modules on the PLC-function, upload modules. But - once you need to download it to a PLC this may be complicate, because the PLC firmware will have a part of the modules on board, so how do you know if you can overload it? also, variables you can not store in the backup. datamodules yes.... but if you feel better doing the backup - it should be not too complicate.... the cable: it is the following wiring diagram valid 2 -- 3 3 -- 2 5 -- 5 BR BB
