Ease in modification of logic, reduced size, means of remote communications and advances in the technology have made PLC Automation Control Panels an edge over conventional relay based systems. Control Systems Engineers has provided PLC based Panels from PLC of Allen Bradley, Siemens, Modicon, GE Fanuc. From small I/O application to the complex I/O systems are provided by the Control Systems Engineers. Control Systems Engineers have developed communication software’s for remote communication of the PLC Panels in various different protocols. With PLC based Panels HMI/MMI are provided to provide the operator various messages and controls of the process plants touch screen MMI are provided. To effective control of the system.
