Why cannot input numeric values/character strings on Omron Touch terminals?
- P
  Phillip GouldSep 9, 2025
  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?
- K
  Kevin MckayAug 27, 2025
  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).

  Nicole PerezSep 12, 2025
  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.

  If some elements on a normal screen of your Omron Touch terminal are not displayed, the quantity of read data might exceed the stipulated restriction. Check the maximum number of elements, create the screen data again, and then transmit all of the screen data in a batch to the NT31/NT31C.

  Alec HarrisSep 5, 2025
  If the touch panel on your Omron Touch terminal is unresponsive, it could be due to external noise. In this case, carry out grounding work. If grounding doesn't resolve the issue, the touch panel might be broken. Test it using the I/O Check in the MAINTENANCE MODE menu. If an error is detected, contact your OMRON service center.

  If you cannot input numeric values/character strings on your Omron Touch terminal, bit 5 of the PT status control area (numeral/character string input) might be set to 1 (ON), or the interlock function is set for the input field and the controlling interlock bit is OFF. Set bit 5 to 0 (OFF). Inputs are prohibited in input fields when the corresponding interlock bit is OFF. Check the status of the corresponding interlock bit and turn it ON.
