☞ 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 co
- Check if the communication speed (9600bps def
- 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
Data bit
Stop bit
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 no
