The Sima2 Master Station from Auma provides actuator control and supervision via open fieldbus standards. By optimising communications between field devices and host system, it simplifies all aspects of configuring, controlling and managing valve actuators and other field devices over the plant’s life-cycle. While suitable for any type or size of petrochemical plant, the Sima2 Master Station is particularly beneficial for extensive sites with large numbers of actuators, such as tank farms and refineries. One Master Station can manage up to 988 actuators in four independent networks, arranged as loop or line topologies. The total cable length without external repeaters can be up to 296 km
per network.
Sima2 uses standardised, proven fieldbus protocols to ensure high-speed and reliable communication as well as long-term security of investment. The system supports Modbus RTU and Modbus TCP/IP to communicate with the host, linking to the actuators via either Modbus RTU or Profibus DP. Cycle times are very short. Integral Ethernet and OPC UA interfaces facilitate data exchange, ensuring future-proofing for IIoT applications. Multiple redundancy options maximise plant availability.
