I have in my possesion, an older Omron PLC without manuals. This is a left over from an old project from the late 1980s. The model is Sysmac C200h Programmable Controller CPU01. I also have the PRO27 programming console and cable. When all connected together and powered up the console displays <PROGRAM>, <MONITOR>, or <RUN> (depending upon the key position) on the first line and PASSWORD! on the second line. Asside from the fact I havent a clue as to what the original password may have been, pressing any console key results with several plaintive beeps. I suspect this it the standard responce of a new unit. Since Omron no longer supports this unit, there are no guides on there web site, no help from that direction. Can anybody in this forum clue me in as to the steps needed to unlock this unit or do I have a nice big fancy paper weight?
