Device identity
What a tool can read to check that this map fits the connected device (SPEC.md section 4.7). Registers with a role are read like any other register.
| Role | Register | Address | Type | Values |
|---|---|---|---|---|
| Serial number | Counter serial number | holding 1280 | string[5] | |
| Firmware | Counter firmware release 1 | holding 1287 | uint16 |
Sources and notes
- MODBUS Communication Protocol for counters with integrated MODBUS or ETHERNET interface · version V001, January 2017 Sections 6 and 8: reading and writing registers
- 7E.64 instruction sheet default speed and address
Source: Finder, "MODBUS communication protocol 7E.64/68/78/86", protocol manual V001, January 2017
- Registers are read with FC03 or FC04 and written with FC10. RTU frames are 8N1; at most 127 registers per read and 29 per write.
- Default Modbus address 1 and 19200 baud (7E.64 instruction sheet).
- Measurements and counters in this map are the IEEE 754 float copies (0x1000 onwards), in V, A, W, var, VA and Wh, varh, VAh. The protocol also has integer copies in two register sets; they are not included.
- Each register's description says which models provide it when not all of them do.
- Information and setting registers use register set 0 (the default) addresses.
