Note: 1. The Serial Gateway function is enabled only for Serial Communications Units of unit version 1.2 and later.

2.The no-protocol function is enabled only for Serial Communications Units of unit version 1.2 and later (and a CPU Unit of unit version 3.0 or later is also required).

3.The Modbus-STU Slave function is enabled only for Serial Communications Units of unit version 1.3 and later.

4.When an NT-AL001 RS-232C/RS-422A Conversion Unit is used, this value increases by 0.15 A/Unit. When a CJ1W-CIF11 RS-422A Conversion Unit is used, it increases by 0.04 A/Unit.
