Loading...Why doesn't the trend graph display agree with the actual time axis on Omron NT21?
The trend graph display may not agree with the actual time axis if the cycle for graph display update processing is longer than the set sampling cycle. To resolve this, delete other elements on the same screen as the trend graph that are allocated words in the host and have a high update frequency, or lengthen the sampling cycle.
What causes the graph display not to change on Omron NT21?
If the graph display on your Omron Touch terminals is not changing, it is likely that one of the percentage display settings — –100%, 0%, or 100% — is incorrect. Ensure that these values are set in the following relationship: –100% value < 0% value < 100% value.
Why can't I use the Programming Console function on Omron NT21 Touch terminals?
The Programming Console function may be unusable due to several reasons. First, the communication settings might be incorrect; ensure the communication method/communication port is set correctly (With C-series PC: 1:1 NT Link; With CS/CJ-series PC: 1:N NT Link). Second, a Programming Console might be connected; disconnect it, as it's not possible to use both simultaneously with all PCs except CS/CJ-series. Third, the PC may not support the Programming Console function; check your PC model's compatibility. Finally, the system program for other vendor’s PCs has been installed (PC models other than OMRON); install the correct system program for OMRON PCs.
Why does the PC mode change to MONITOR mode on Omron NT21?
The PC mode changes to MONITOR mode because this is an Omron Touch terminals specification when host link communication is used. When using a PC that can also be connected using the NT link method, use an NT link connection as there is no mode change with the NT link method.
Why can't I input numeric values on Omron NT21?
If you are unable to input numeric values on your Omron Touch terminals, it is likely that the upper/lower (max./min.) limit check for numeric value input is in effect. Check the screen data’s upper/lower (max./min.) limit check setting for numeric value input, and correct it if necessary.
What causes incorrect numeral/text display on Omron NT21?
An incorrect numeral or text display on Omron Touch terminals can stem from several causes. If the memory table entry is allocated words in the host, the display updates according to the host memory contents; avoid allocating words for fixed-value memory table entries in the host. Another cause could be a drop in battery voltage destroying memory table data (NT21 with optional Battery); replace the battery and initialize the memory table. If the resume function is ON, initial screen data memory values won't write to memory tables (NT21 with optional Battery); initialize the memory table or disable the resume function. Lastly, setting two words in a numeral memory table entry for an indirect address can cause issues; set only one word in the numeral memory table entry.
Why does the buzzer sound and the RUN indicator turn OFF on Omron NT21?
If the buzzer sounds and the RUN indicator is OFF on your Omron Touch terminals, it could be due to malfunction from external noise. Another possibility is that the PT has developed trouble, in this case, contact your nearest OMRON representative.
Why is nothing displayed on the Omron NT21 Touch terminals screen?
If nothing is displayed on the screen of your Omron Touch terminals, it could be due to the screen No. 0 has been read at the host side, so change the screen number. Alternatively, the system startup waiting time may not have elapsed yet; the display will appear after the waiting time has elapsed.
How to troubleshoot communication issues with the Support Tool on Omron NT21?
If you're experiencing communication issues with the Support Tool on your Omron Touch terminals, there are a few potential causes. First, the Transmit mode may not have been established; display the System Menu and select the Transmit mode. Second, you may not be properly connected to the Support Tool; check the installation of the connector cable. Finally, the PT model setting and direct connection setting at the Support Tool might not match the NT21, NT31/NT31C, or NT631/NT631C; use the PT Configuration settings of the Support Tool to set the PT model and direct connection settings that match your device.
What to do if the Omron Touch terminals touch panel does not respond?
If the touch panel on your Omron Touch terminals is unresponsive, it could be due to malfunction from external noise. Another possibility is that the touch panel is broken. To check this, test the touch panel with I/O Check in the MAINTENANCE MODE menu. If there is an error, contact your nearest OMRON representative.
