5) Communication
The unit provides access to the internal registered values using the Modbus Protocol.
The diagram below shows the recommended connections to the Phoenix connectors on
the back of the unit for either half-duplex or full-duplex (RS485).
Note: The termination resistor is not included above and the user needs to connect this
resistor as needed by the wiring configuration.
The Modbus address registers defined below are input register type (Function Code 04)
using two’s complement representation for the signed integers.
