What application in your experience has demanded the most complex PLC program?
I suppose I should clarify what manner "complex" I'm asking about. So a PLC with 10,000 I/O controlling a few thousand valves all in the exact same way, with the same 4 or 5 rungs of code copied/pasted a few thousand times, is not what I picture when I think of complex. When I think of complex, I picture a few thousand rungs* of (for the most part) unique code, each rung* (for the most part) having required deliberate thought by someone with vast knowledge and above average cranial processing power.
Palletizers stand out in my mind as being usually pretty complex
*rungs, may be substituted for lines of ST or whatever. Not necessarily ladder.
