Applies To:
  • CitectSCADA 4.xx, 5.xx

Summary:
The default value that the MODBUS driver uses for device initialisation is 0. I need to use the MODBUS protocol but my device does not have a register 0. 

Solution:
From MODBUS version 2.01 you can use the following Citect.ini setting:

[MODBUS]
InitUnitAddress=XX

Where XX is the address you wish to use.
