1. Reasons for Touch Screen Issues:

a. If the touch screen displays an error message, refer to the user manual based on the specific error code to identify and resolve the issue.

b. For NS series screens, if the lower right corner shows "connecting" but the screen does not display anything, navigate to the system menu and check the NS COM port settings, as well as the PLC protocol and baud rate. Ensure that any unused serial ports are set to NONE.

c. For NT31 (C) / 631 (C) series, if the screen shows "system initializing" but remains blank, go into the system menu to verify that the NT COM port settings match the PLC protocol and baud rate. If the screen appears white or black, check the system control area settings in the NT and ensure the display is correctly assigned to the appropriate channel.

d. For NT5Z/NP series, if the screen shows “Initial PLC Control Area Fail!!!” or “Communication Error 3,” and the display is not working, review the communication settings in the man-machine interface or PT settings within the software. Confirm that the serial port settings, PLC protocol, and baud rate are all consistent.

2. PLC-Related Causes:

a. Damaged cables or incorrect wiring can cause communication issues. Please double-check the wiring connections and ensure they are properly secured.

b. The PLC settings must be configured with the correct protocol, such as HOST LINK or NTLINK, along with the proper baud rate. When in online programming mode, make sure these settings are transferred to the PLC, and verify that the corresponding DIP switches are set correctly for optimal performance.

By following these steps, most common touch screen and PLC-related problems can be resolved efficiently, ensuring smooth operation of your system.
