9.4 Modbus and OPC mapping
Following is a table of parameters that can be used for Modbus and OPC mapping. These
parameters are used by the Smart Wireless Gateway and can be found in the web interface of
the Gateway. Some of these parameters are analog values and some are discrete, and this is
noted in the description. The Setpoint parameters are used to drive the output channel and for
the readback of the state of the output channel.
