Automation & Control System
Automation and control system of the biogas plant is based on industrial sequence controller Siemens CPU315-DP2 and application of distributed peripheral system Simatic ET200S with operator's touch screen control panel OP277 Touch. Together with sensors and actuation mechanisms the automation system secures automatic process control and biogas plant technological processes protection and regulation.
Interaction between units is performed by means of PROFIBUS and MPI networks using RS-485 physical interface. Master program is developed with the application of Simatic Step7 development system and recorded to memory stick.
