I have been tasked with outfitting our facility with Andon lights. For those not familur Andon lights are a used in lean mfg. methodology to communicate the state of the cell with a tree light or strobe. Each color meaning maintenance, inspection needed, etc. Most of the machines are relay logic machine and some are just stand alone areas with no existing controls. I am considering using a PLC to monitor the system and provide a central monitoring station. My question is how far can I run sensors? Most likly 24vdc. I plan on using a Horner plc which has the capability to act as a web server. I am hoping to output the status of each area to the webpage so the appropriate persons can check in on the status of each area if they are not on the floor. Any suggestions on the best way to do this?
