MODBUS COMMUNICATION PROTOCOLS (SERIAL TYPE = DAT1400)
The instrument parameters that can be read or programmed through the available communication interfaces on the
instrument, depending on the hardware configuration, are listed in the following table.
R-type registers are the readable ones while W-type registers are the writable ones.
In case of Modbus TCP protocol, the address of the instrument ("Unit Identifier" field) must always be FFh. If a
fieldbus (other than Modbus) is used, only R or R/W registers will be present in the input area, and only W or
R/W registers will be present in the output area.
The registers are 16 bits in size.
