Communication Interface Specifications
You can use the USB port or RS-232C/422 connector of the Controller to perform serial communication with
external devices such as a personal computer or programmable controller.
Serial communication functions in the RUN mode. Communication cannot be performed in the ADJ or MENU
modes.
<USB>
This interface allows Full speed (12 Mbps) communications compliant with USB2.0 with a PC equipped with
the same USB interface.
<RS-232C/422>
This interface allows data communications compliant with the EIA RS-232C/422 standards up to a maximum
speed of 115200 bps.
For details on how to set the communication specifications, refer to the User's Manual.
