Communication by IEC 62056 protocol
The IEC 62056
standard defines the communication protocol that is designed for electricity consumption measurements, data exchanges with electricity meters, controlling the tariffs and load regulation.
The protocol includes five communication modes (A, B, C, D, E
) which may, or may not be supported by the electrometer.
- In the A, B, C modes, the control system is active (Master) and the electrometer is passive (Slave).
- In the E mode, the control system acts as client and the electrometer works as server.
- In the D mode, only one way transfer is available allowing only reading.
Communication by OPC server
For the IEC 62056
protocol communication with the PROMOTIC system the OPC
servers delivered by third parties can be used.
