PLC Laws # 11.1 - THERE MUST BE SPARES

PLC Laws Playlist https://www.youtube.com/playlist?list=PL3y71jAPOdZDCQhpRcy4FpDCQ0Np1GZxb PLC Laws are from a thread started at Mr. PLC in 2006. The intention was to pass along knowledge to up-and-coming programmers. Drawing from PLC gurus' personal histories, these light-hearted PLC laws are educational and entertaining. Everyone can still learn or relearn from them today. The original thread can be found here: https://forums.mrplc.com/index.php?/topic/9522-plc-law/ You can still add to this classic thread... It's great to be able to laugh at ourselves while educating others.
