Why is nothing displayed on the Omron Touch terminals screen?
If nothing is displayed on the Omron Touch terminals screen, it might be because Screen No. 0 has been read at the host side. Try changing the screen number. Alternatively, the system startup waiting time may not have elapsed yet; the display should appear after the waiting time is over.
Why do the digits in numeral display come out as * on Omron Touch terminal?
The digits in the numeral display come out as asterisks because the number of digits of a numeric value in a numeral memory table exceeds the set number. Confirm the values of the PLC words allocated to the numeral memory table. Allocate one PLC word to each numeral memory table.
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 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 '[Memory Switch Corrupted]' mean on Omron NT31 Touch terminals and how can I solve it?
The '[Memory Switch Corrupted]' message on your Omron Touch terminals indicates that the memory switches have been initialized due to discovery of an error in the memory switch settings. Set the memory switches again using the System Menu and the “System” settings under “PT Configuration” at the Support Tool.
What to do if Omron Touch terminal displays '[Touch Panel is disconnected]'?
The '[Touch Panel is disconnected]' message indicates that the touch panel cable (film cable) inside the NT31/NT31C is disconnected. Contact your OMRON service center.
How to fix Omron Touch terminals when the power LED fails to come ON?
If the power LED on your Omron Touch terminal doesn't light up, first ensure the device is correctly connected to a power source. If the connection is correct, but the LED still doesn't turn on, it's possible the power supply fuse has blown, in this case you should 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.
What does '[Tool Transmit Error] Error detected while downloading' mean on Omron NT31 Touch terminals?
If your Omron Touch terminal displays the message '[Tool Transmit Error] Error detected while downloading', it could be due to a defective connecting cable, so check the cable connection and perform a conductivity test, replacing the cable if there's a fault. Malfunction due to external noise is another possibility, so carry out grounding work.
How to resolve '[Programming Console Error] Programming Console Function does not RUN' error on Omron Touch terminal?
The '[Programming Console Error] Programming Console Function does not RUN' error appears because the connecting cable is defective, there is malfunction due to external noise, or a Programming Console is connected. Check the cable connection and perform a conductivity test. If there is a fault, replace the cable. Carry out grounding work. Disconnect the Programming Console.
