• All necessary timers and intrinsically safe relays to control the system on an automatic starting and stopping basis
• All the interlock, monitoring and controlling of the CNG compressor package is done through PLC based control system of proven type and the Make of the PLC is Siemens(S7 300),  Schneider M340 PLC and Allen Bradley (Micrologix 1200) of latest version  or equivalent 
• PLC is housed inside flameproof IIA/IIB (Ex’d’) enclosure. Local operator panel is provided on the flameproof enclosure. The operator panel is provided for parameterization, indication, monitoring, and alarms and first out sequence of the system. PLC system have memory modules for storing user programs, symbol lists, Program comments and should facilitate debugging / trouble shooting without the application program. Program is ladder logic and communication is in English for each run.
• The Protocol and the other details for Interfacing is specified clearly. The Communication protocol is an open protocol i.e. MODBUS RTU Protocol for communicating with slave devices.
• Power supply to PLC supply is 24 VDC.
• The PLC has an Industrial Ethernet Module with min TWO Ethernet port and Modbus RS-485 (2-wire) port, Configured and programmed, to establish remote communication of PLC with the SCADA server.
