HIGH-PERFORMANCE MASTER STATION optimises VALVE ACTUATOR CONTROL
T
he new SIMA² Master Station from electric actuator manufacturer AUMA
provides high-performance actuator control and supervision via open fieldbus standards. By optimising communications
between field devices and the host control system, the SIMA² Master Station simplifies actuator installation, commissioning and operation, especially in tank farms and refineries with large numbers of actuators. A single SIMA² Master Station can manage up to 988 actuators in four independent networks, arranged as loop or line topologies. SIMA² uses standardised,
redundancy protects against cable breaks, for instance, while hot-standby architecture provides redundancy at system level. Integral Ethernet and OPC
UA interfaces facilitate data exchange, ensuring future- proofing for IIoT applications. A compact and ergonomic
Powerful, flexible and scalable: AUMA’s SIMA Master Station uses open fieldbus standards to supervise and control large numbers of actuators in tank farms and refineries
proven fieldbus protocols to ensure high-speed and robust communication as well as long-term security of investment. Cycle times are extremely short, enhancing process efficiency. 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. Multiple redundancy options maximise plant availability. Modbus RTU loop topology with built-in
design and a choice of housing options minimise installation time and cost. Communication parameters can be easily set, and fieldbus networks configured, commissioned and tested, directly from the SIMA² Master Station using either the large multi-touchscreen or an external browser.
Comprehensive diagnostic
functions facilitate fault-finding and maintenance. l

MILDEW-RESISTANT COATING KEEPS STORAGE TANKS LOOKING BETTER FOR LONGER
T
o enhance efficiencies for asset owners in the oil & gas storage tank segment in the EMEAI
region, Sherwin-Williams Protective & Marine Coatings has launched its new epoxy coating offering mildew- resistant corrosion protection with a long-lasting, more aesthetic finish. The high-solids, high-build, fast- drying polyamide Macropoxy 646MR
primer builds on the existing proven Macropoxy 646 technology, offering high chemical and abrasion resistance inside as well as outside of the tank with the added formulation of outstanding mildew resistance. The new Sherwin-Williams solution
keeps tanks and pipelines working more efficiently with a more aesthetic finish than previously available. With low volatile organic compounds (VOCs), application can be performed on site or in shop by brush, roller or airless spray. “This coating is simple
to apply without having to completely remove existing systems, and resists the
growth of mildew on the exterior of tanks or external pipelines,” says Michael Harrison from Sherwin- Williams Protective & Marine Coatings. Designed for use in maintenance,
repair or in new construction, Macropoxy 646MR is an ideal durable corrosion protection coating for storage tanks, fixed roofs, floating roofs, vessels and pipelines. The range of protective lining
products offered by Sherwin-Williams is tailormade to each specification, combining exceptional anti-corrosive performance with effective chemical resistance. l
