Why is the Omron NT31 touch panel not responding?
If the Omron Touch terminal touch panel isn't responding, the issue might be external noise. Grounding work may resolve this. If grounding doesn't help, test the touch panel using the 'I/O Check' function in the MAINTENANCE MODE menu. If there's an error, it may indicate a broken touch panel.
How to troubleshoot Omron NT31 when it cannot communicate with the Support Tool?
If your Omron Touch terminals cannot communicate with the Support Tool, ensure the Transmit mode has been established by displaying the System Menu and selecting the Transmit mode. Check the connector cable installation, and verify that the PT model setting and direct connection setting in the Support Tool match the NT31/NT31C settings, using the “PT Configuration” settings of the Support Tool.
What does '[Screen Data Error]' mean on Omron NT31 and how to fix it?
The '[Screen Data Error]' message on your Omron Touch terminals indicates that the screen data is corrupted, possibly because the power was switched OFF during screen data initialization, checking, or transmission, or that illegal data has been written to the screen data memory. Initialize the screen data memory via the System Menu, and then re-transmit the screen data.
How to fix a dim display on Omron Touch terminals?
