When it Comes to Interfacing with Plant-Wide Distributed Control Systems
BASLER GETS A STANDING OVATION
The initial Excitation Control System, ECS2100, (predecessor of the Basler DECS-2100) was first connected to an Emerson Ovation™ system on the test floor of a large east coast utility during a factory acceptance test in 2002. Since then, many Customers have used a variety of Distributed Control Systems (DCS) to communicate with the ECS2100 and DECS-2100. Today, hundreds of ECS2100 and DECS-2100 systems communicate with many popular DCS, including Emerson Ovation™, GE Mark V, GE Mark VI, GE Mark VIe, Siemens T2k, Siemens T3k, and others. Communication methods used include hardwired I/O, Modbus, and Modbus over Ethernet. The DCS may communicate with only the channel in control or may communicate with each channel independently if desired.
The Modbus map (addresses of coils and registers) is also the same Modbus map used by the Basler HMI touchscreen. The output coils and registers in the Modbus map allow the DCS to gather system alarms, status, and output values. If used, the input coils and registers allow for excitation control and setpoint inputs. The Modbus map includes 32 programmable input coils, 240 programmable output coils, 32 programmable input registers, and 160 programmable output holding registers. Customers may choose which features they need to control excitation and may gather as much or as little feedback data as necessary.
