☞ The controller does not communicate with the Host-PC.
Cause A defective cable is used, errors in wiring, an error in setting COMM ID of the controller, or damage on
the communication port (either on PC side or on the controller side).
Solution 1. Please check the settings of the application S/W and the controller.
- Check if the controller’s COMM ID is listed on the application S/W.
- Set the different COMM ID when two or more controllers are installed.
- Check if the communication speed (9600bps default) is the same as the setting on the S/W.
- Make sure that the PC’s COM port is set correctly on the S/W.
- The parameters at the S/W should be set as following:
Parity bit : NONE
Data bit : 8bit
Stop bit : 1bit
2. Check the line connection for communication.

3. In case of setting RS485 communication, we recommend to use line-end resistors of 120 Ohm
between the RTX (+) and RTX (-) lines. Apply the same resistors to the converter RS485 lines.
Consult a service center or an electric technician if you are not sure how to do it.
4. When a multi-drop communication doesn’t work, test one-by-one communication first.
5. If the trouble remains after the procedure above, contact a designated service center.
