I am fairly new to PLC Programming and hope that I may be able to get some advice you guys :) However, I have around 18 months experience building SCADA systems which means I have a sort of overall understanding as to how PLC Programming is done. I have an upcoming task which is to involve some PLC coding. I don't have the exact details yet of it yet but I expect that is going to be mainly focused on transferring data from one PLC to another (ControlLogix, so development will be done under RSLogix5000 I guess?). I have yet to be explained exactly what data is being passed between the 2 PLC's but please could somebody explain to me the steps taken to read from/write to another PLC? I have been looking into the MSG function and the Message data type but I've not yet been unable to build up a clear representation as to how these are used. Any help and advise would be massively appreciated! Thanks
