Issue
Does the part number for Modbus RS-485 (IA-DRV-MOD) have to be purchased four times in order to support all four available RS-485 ports?
Environment
Niagara R2 all versions
Cause
Job site will integrate to four different vendor products using Modbus to one UNC-520.
Resolution
A UNC-520 supports up to four separate Modbus Async Networks each using a separate ModbusAsyncService.
Only one part number has to be ordered for the UNC (part # IA-DRV-MOD).
