Modbus Slave Module Parameter Mapping
The following tables show which measurements are provided by each of the four
Modbus Slave modules. The source for each measurement is shown (“Source ION
Module”) so that you can easily delete parameters if you want to access different
data. Note that the Modbus Register remains the same if you link a different
parameter into one of the Modbus Slave module inputs (i.e. any value you link to
Modbus Slave module #1, Source Input #1 will use Modbus Register 40011).
