Connection and addressing notes
- Protocol
- Modbus
- Register address format
- both decimal and hexadecimal addresses are listed
- Register addressing
- the decimal address is used directly as the 0-based register offset (for example 350)
- LONG and LONG100 values
- occupy two consecutive 16 bit registers
- Access column
- the Read/Write column marks each register as R or RW
Registers in the map: 181 (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.
