I don't see from your screenshots how you setup Tag and Modbus pointer settings. Try to change offset in Modbus pointer settings from 1 to 2 because according your screenshots address of register 40002. Also, do you trying to connect by using TeslaSCADA2 Runtime? Because you can't connect to the real device by using TeslaSCADA2 IDE. It has only emulator, but not has Modbus driver.
