Abstract: Infrared Free Electron Laser (IRFEL) which is under development at RRCAT Indore. The IRFEL machine consists of 90keV thermionic gun as electron source, beam transport line, 25MeV Linear Accelerator (LINAC) and an undulator magnet. There are various magnets on beam transport line. These magnets are energized by power supplies. These power supplies have local as well as remote control and located at equipment hall. The control room and equipment hall are at approximate distance of 300 m. When in operation Free Electron Laser generates X-ray radiations which are harmful for human body. Hence, when FEL is operational no personnel can enter FEL hall. Therefore, power supply kept in this hall needs a remote operation. In this paper, a distributed control system hardware and parameter display for Controlling and monitoring of power supply is designed based on network management protocol i.e. Modbus protocol makes the system flexible for Humans
