Connection and addressing notes
- Protocol
- Modbus
- Register addressing
- addresses are given in hexadecimal and used directly as 0-based offsets (0x300 = 768)
- Long values
- 32 bit and occupy two consecutive 16 bit registers
- Maximum variable or group size
- 100 bytes with software version below 1.09
- Maximum variable or group size from version 1.09
- 240 bytes
Registers in the map: 137 (the first 50 are listed below; the browser reader and the data loggers use the complete map). function 3 (holding registers). byte order big-endian. data types: integer, word.
