Emerson Network Power has released an ASCO Ethernet redundancy and I/O solution designed to simplify efficient operation, reliability, and serviceability of quad-redundant programmable logic controllers (PLCs) for paralleling control switch gear.
The ASCO Ethernet redundancy and I/O solution comprises software, PLC, and I/O configurations that represent the only quad-redundant control method designed specifically for paralleling control switch gear. It also includes a full set of system diagnostics that signal any failure, not just those that could bring down the system. The information is displayed on the master PLC, I/O communication status screen and displayed and logged on the ASCO PowerQuest Power Monitoring and Control System.
