Production
List
The Production and consumption
Registers can be used to create custom
Modbus interface ranges. An example:
If field inputs register address 0 is put
into the first slot of the production
list, the field inputs register value will
be available in the first slot of the
Modbus Production Data Register range.
Production data is data provided by the
device and Consumption data is for data
provided (written) to the device. Note
that the values must be Modbus Register
Address (i.e., Register Number - 1) not
Register Number.
