Just curious - for those of you who do handle drawings - How do you decide your component IDs?
I'm smack in the middle of the automotive world - but we have been doing more watewater treatment facilities and other industries lately. Typically I always use a ladder diagram and the ID for the component has the page #, line # in the Id such as 1105CR - which would be page 11 line 05 Control Relay.
Most of the 'electrical cad software' allows IEC like schemes where you just use CR1, CR2, etc - and just start at #1 for the wire and go up to whatever number. I've thought of switching to this simpler style to make labels / etc easier to print & read, but I'm not sure how common it is VS page & line numbers.
I understand the thought process behind using the page/line # to quickly look up the issue in the prints - but we typically do small machines with no more than a few relays or push buttons - so the simpler numbering scheme is attractive.
I'd love to hear your 2 cents.
Also - I'm very pro using the I/O address as the wire # and component ID - such as Q5.0CR - where output 5 bit 0 is the control relay's ID. This makes it possible to open the program without looking at the schematics and quickly find I/O points. My colleague insists on using the page/line number scheme even for I/O points, but doesn't really have an argument to back it up - but I've seen both used.
