Features of PLC
- It is also possible to connect an RS-232C/RS-422A conversion unit (NT-AL001) to the RS-232C port to enable 1:N communication.
- The CJ1W-SCU□2 model enables connection to high-speed external devices by improving communication speeds (up to 230.4 kbps) and reducing data transfer times to the CPU unit.

- *1Serial Gateway: The serial gateway function can be executed even in protocol macro mode.
- *2Non-protocol: An external interrupt task can be started when receiving data without procedure. When combined with a CJ2 CPU Unit version 1.1 or later or a CJ2M CPU Unit, high-speed non-protocol (DRXDU/DTXDU instructions) is possible.
- *3. Current consumption for the serial communications unit alone.
When using the NT-AL001, power is supplied to the NT-AL001 from the serial communications unit. When using the NT-AL001
, the current consumption increases by 0.15 A for each NT-AL001.
The current consumption value differs for each unit. Please be careful when replacing units.
x: 0.15 A is added per port for the 5 V power supplied from the RS-232C port to the NT-AL001.
