I need a tag naming convention to help me accurately translate infomation from P&ID drawings to my PLC programs. Is there some kind of standard out there that is the programmers equivalent to the ISA Symbols and Identification Standard?
Example:
A symbol shown as R300 PIT on a P&ID drawing works well to show the origin of an analog signal going to a plc, but once it is in the realm of software, what do you call the unscaled value, the scaled value, the filtered value, the limited value?
If anyone knows where I can find such a standard, I would greatly appreciate your help.
thanks,
Rich
