AUMA has launched its new SIMA² Master Station, providing high-performance actuator control and supervision via open fieldbus standards. By optimising communications between field devices and the host system, the SIMA² Master Station simplifies all aspects of configuring, controlling and managing actuators and other field devices over the plant’s life cycle. While suitable for any type or size of the plant, across all industry sectors, SIMA² Master Station is particularly beneficial for extensive sites with large numbers of actuators, such as tank farms and refineries.
One SIMA² Master Station can manage up to 988 actuators in four independent networks, arranged as loop or line topologies. Total cable length without external repeaters can be up to 296 km per network.
SIMA² exclusively 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 extremely short, enhancing process efficiency.
Integral Ethernet and OPC UA interfaces facilitate data exchange, ensuring future-proofing for IIoT applications.
Multiple redundancy options maximise plant availability. Modbus RTU loop topology with built-in redundancy ensures communication even in the event of a cable break, for instance, while hot-standby architecture provides redundancy at the system level.
Communication parameters can be easily set, and fieldbus networks configured, commissioned and tested, directly from the SIMA² Master Station, thus speeding up commissioning. During normal plant operation, SIMA² coordinates all actuator commands and feedback signals, reducing host communications to an absolute minimum. Comprehensive diagnostic functions facilitate fault-finding and asset management.
