Industry: Power and Energy
Product: Modbus Ethernet to Serial Gateway
Aggreko, a world leader in temporary power and temperature control rental services, deploys large power installations in remote locations. A typical installation might include a set of six generators and a transformer housed in a 40 foot container. A SCADA system monitors and controls the diesel engine sets and various I/O for generators and transformers. The individual generators and transformers also have fire safety systems that use serial interfaces. Additional control components include Allen Bradley PLC® units operating on a MODBUS/TCP protocol, SCADA, serial and Modbus protocols. How do you tie it all together?
B&B Electronics provided Aggreko with custom panel assemblies that incorporated industrial Modbus Ethernet to serial gateways. The gateways connect serial devices to an Ethernet-based SCADA system and provide conversion to the Modbus/TCP protocol. Each transformer unit contains a NEMA-rated panel kit from B&B Electronics that uses two RS-485 data acquisition modules for I/O connections, a Modbus Ethernet serial server, a power supply, relays, and wiring. B&B’s unmanaged switches tie all the Modbus Gateways together and connect them to the SCADA master. Monitoring and control of the transformers is seamless.
