Is there an ISA or IEEE standard which details symbols that one would use to create a logic diagram representing the PLC program?
I only have a few diagrams that are mostly the same project to project; one detailing the SFC state machine, one detailing a governor so it is just a block diagram of the transfer function essentially, and another that is essentially a print out of a matlab simulink model so it is mostly squares with different labels on them and some summing junctions.
On a couple I've created diagrams illustrating a series ESELs or MUXes and min/max blocks with multiple inputs so people can see what input is going to end up at the output, and one with a series of AND and OR gates which was kind of a pain.
How often or for what percentage of the program does everyone create drawings that detail how the program works?
I haven't found any good examples or standard documents. Does anyone know of one?
Thanks
