What causes the buzzer to sound and the RUN LED to be OFF on Omron Touch terminal?
If the buzzer has sounded and the RUN LED is OFF on your Omron Touch terminal, it could be due to malfunction caused by external noise or the NT31/NT31 has developed trouble. Carry out grounding work or contact your OMRON service center.
Why cannot input numeric values/character strings on Omron Touch terminals?
If you're unable to input numeric values or character strings on your Omron Touch terminal, it could be because bit 5 of the PT status control area (numeral/character string input) is set to 1 (ON). Set bit 5 to 0 (OFF). Alternatively, the interlock function might be set for the input field, and the controlling interlock bit is OFF. Check the status of the corresponding interlock bit and turn it ON, as inputs are prohibited in input fields when the corresponding interlock bit is OFF.
Why does the PLC mode change to monitor mode on my Omron Touch terminal?
The NT31/NT31C changes the mode when host link communications are used. When using a PLC that can also be connected using the NT Link method, use an NT Link connection (there is no mode change with the NT Link method).
Why is the display too faint on my Omron NT31 Touch terminals?
If the display on your Omron Touch terminals is too faint, it's possible that the contrast is too high. Try reducing the contrast.
What does '[Tool Transmit Error] Check Sum Error occurs while downloading' mean on Omron NT31 Touch terminals?
If your Omron Touch terminal displays the message '[Tool Transmit Error] Check Sum Error occurs while downloading', it might be due to malfunction caused by external noise. Carry out grounding work.
What does '[Screen Data Error] Screen Data corrupted. Initialize Screen Memory, and download Screen Data again' mean on Omron Touch terminals?
If your Omron Touch terminal displays the error message '[Screen Data Error] Screen Data corrupted. Initialize Screen Memory, and download Screen Data again,' it indicates that the power was switched OFF during screen data initialization, checking, or transmission; transmission of screen data was interrupted; or illegal data has been written to the screen data memory. Initialize the screen data memory by operation at the System Menu, then re-transmit the screen data. If the problem persists, contact your OMRON service center.
Why has the PLC mode changed to the monitor mode on my Omron NT31 Touch terminals?
This is an NT31/NT31C specification. When using a PLC that can also be connected using the NT Link method, use an NT Link connection (there is no mode change with the NT Link method).
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 enable System Menu on Omron Touch terminal?
If the System Menu cannot be called up on your Omron Touch terminal, Display System Menu under Change System Settings in the System Installer mode might be set to Disabled. In the System Installer mode, set Display System Menu to Enabled.
Why can't I input numeric values on my Omron Touch terminal?
If you cannot input numeric values on your Omron Touch terminal, the upper/lower (max./min.) limit check for numeric value input might be in effect. Check the screen data’s upper/lower (max./min.) limit check setting for numeric value input, and correct it if necessary.
