ABB B21

Below the registers with the ABB B21 emulation firmware. More Eastron kWh meters using the same register configuration. This setup could be used in more configurations.

Default settings

The default dongle settings are:

9600 baud 8N1 ... modbus address 2

Register values are available in FC04, UINT32 and INT32

No value = 0, for example when U2 isn't available (single phase system) this value is 0.

Note

The mapping is made for the SMR 5 meters. This is common in EU but in the Netherlands versions 4 and 2 are available too.
