(With the NT631/NT631C, monitoring will continue in the othertable and any changes in those words will appear on the screen.)S No other operations can be performed while the popup input window is beingdisplayed on the screen. (The PT can be controlled from the PC if the PT isoperating.)2.

(This buzzersound can be disabled with the PT’s touch switch sound setting.) In thiscase, check the valid range of the data area in the connected PC and enterthe word address again.
The error message will be cleared when a validword address is entered.If the Back touch switch is pressed before the Write touch switch, the inputwill be cancelled and the PT will return to monitoring the original word addresses.274Section 2-17Device Monitor Function2-17-7 Using the Error Log ScreenThe error log screen reads the error log in the PC (the errors that have occurredin the PC) and lists the errors in order of their priority. It is also possible to clearthe highest priority error.NT31/NT31C ScreenError Log display areaWith the NT31/NT31C, 5 error records can be displayed in one screen.
The highest priority error must be cleared in order to display the sixth error record.NT631/NT631C ScreenError Log display areaWith the NT631/NT631C, 30 error records (15 records × 2 columns) can be displayed in one screen. The highest priority error must be cleared in order to display the thirty-first error record.Error Log Display AreaThe error log display area displays errors in order of their priority. (With theNT631/NT631C, the highest priority error is displayed at the top of the left column and the lowest priority error is displayed at the bottom of the right column.)The screen will be updated if another error occurs while the error log is beingdisplayed.Clear Error Touch SwitchClear the highest priority error (displayed at the top or top-left) by pressing theclear error touch switch.
The error will be removed from the display area once itis cleared, but the same error may occur again immediately if the cause of theerror hasn’t been eliminated.

The FAL number will not be displayed.• FAL and FALS numbers will be displayed in the jjj area if they are generated by the system (such as FAL 9B and FALS 9F) rather than the FAL(06) andFALS(07) instructions.CS/CJ-series PCs:• The FALS number won’t be displayed if there is a higher priority error in theerror log.• FAL numbers are always displayed if the error is occurring.2-17-8 Errors Occurring during Device Monitor OperationWhen an error occurs in NT31/NT31C or NT631/NT631C operation while theDevice Monitor function is being used, find the symptoms in the following tableand perform the corresponding remedy.Error in Device Monitor OperationPT symptomsThe screen doesn’t changeeven though the DeviceMonitor function has beencalledll d ffrom theh PT statuscontrol area.The words that were beingmonitored the last time thatDevice Monitor was used arep y the next timenot displayedthat Device Monitor is called.Probable causeRemedyThe communications protocol Check the memory switches (fourth screen) and set thesetting at the PT is not 1:1 NT connected PC’s serial port protocol to 1:1 NT Link orLink or 1:N NT Link.1:N NT Link.
