Generic Modbus controllers support one of two point address ranges—5 Digit, or 6 Digit. You need to be aware of which address range each controller on your system supports. Specify the supported Point Address Range on each Generic Modbus Outstation Form (see Specify the Point Address Range).
Specify the individual point Address on each Generic Modbus Point Form(see Configure Common Point Properties). Points on Generic Modbus controllers use addresses within the 5- and 6-Digit address ranges listed below. Be aware that each type of controller has its own specific address range—refer to the controller documentation for the address range that applies to a specific type of controller.
