The CS-IEC-DCU is a Data Concentrator Unit that acquires data from:
- Various meters (monitoring feeders) – via polling using Modbus-RTU
- Field devices (circuit breakers, isolators, switchers, power / current / coltage transformers,etc.) – via digital inputs
The CS-IEC-DCU polls configured meters in a continuous fashion and maintains the current values in contiguous internal registers. This aids in retrieving all meter data by a SCADA Master or RTU in minimum number of polls from the DCU.
The protocol support for communication with the Control Centre / Supervisory node / RTU are: IEC 870-5-104 or Modbus-TCP.
