4 Assignment MODBUS holding register 9001 to virtual input "AI3"
Assignment of IOs and display of designations
With the factory default assignment, the designations of the inputs and outputs in the display
correspond to the connection designations (see circuit board and connection diagram imprint).
If you make a different assignment, e.g. assigning the input "E2" instead of the previous hardware
input "E1" under "AI1" (analog input 1), the display and setting is still under "E1". In other words, the
designation of the connection and the designation in the display no longer match.
Example of possible assignment for analog input AI1 and AI2
Factory assignment
The actual input "E1" is assigned to the virtual input
"AI1".
The actual input "E2" is assigned to the virtual input
"AI2".
