Im Work in a Thermal Power Plant. We look to automatize our old alarm anunciator whit a new PLC. We have a 500 inputs and 300 outputs for this aplication. We need a PLC with redundant power supply and redundant processor. I need to implement a HMI interface for the operators. We need a trensd of principal variables of the thermal cycle. We need to post a alarm summary with time stamp for analyze possyble problems in the plant. Also we need to implement automation in start and stop motors, pumps, open and close valves, and very other equipment as a HV breakers, electrical protections, etc. We look the Omron CS1 Duplex for this aplication. What another brand or model reccomend??? I'm not a PLC Expert. I apreciate very much your reccomendation about this selection. Many Thanks.. Moved to this forum - you will probably get more answers on other brands here - JA
