Hey boys. We are having trouble at our plant with tagnaming becoming an issue. Everyone here agrees that descriptive tagnames are nice, but the problem lies in the fact that some lines here are too damn big. We just installed a new line which has 4 PLC5000 communicating with each other. Because the tagnames were becoming so long, abbreviations were used. Now we have tagnames such as this #1_RC_DR_RUN_PB. They get worse than this. This really becomes a problem when someone does not know what the abbreviations stand for. Also, RC_#1_DR_etc can be a problem. Meaning that if I am looking for #1 RC, and the programmer called this bit RC_#1, I will have trouble finding it. The ladders are divided into subs, but those are around 200 rungs long. We are trying to come up with a way to standardize how we label real world I/O in the PLC. The most popular suggestion is to simply call inputs their wire number in the PLC, and use the description to help people understand what the bit they are looking at is driving. Does anyone else have a "standard" they use to keep tagnames short, without it being too complicated to troubleshoot? Just wondering what everyone else is doing.
