Modbus via TCP/IP (RJ45), standard port 502, is built into the control system as standard.
The parameter list (see manual) contains a column that indicates which register the parameter belongs to and which values can be sent.
- Address = Parameter id +1.
- 3 = Input register.
- 4 = Holding register.
Values are normally sent as int16.
Some parameters with larger numbers (32 bits) utilise the next higher parameter ID number as the high number.
Values with decimals are displayed as the value * 10 (1 decimal).
