Press the error screen’s OK touch switch torestart the Device Monitor function.If the Device Monitor function was called by switching screens during operation,the PT will revert to the screen that was displayed when the Device Monitor function was called.Refer to 6-2 Responding to Displayed Error Messages for details on errorscreens and correcting the indicated errors.2-17-5 Using the Registration Monitor ScreenThe registration monitor screen can be used to display the PVs of a specifiedwords and change word PVs. It is also possible to force-set, force-reset, andclear the forced status of bits and timer/counter Completion Flags.Reference:S When the PC is in RUN mode, it is not possible to change word PVs or forceset, force-reset, or clear the forced status of bits (including timer/counter Completion Flags.)S A word or bit address that has been specified will remain valid until the PT isturned OFF or reset.
The settings will remain valid even if the Device Monitorfunction is closed, so the last valid settings will be displayed the next time thatthe Device Monitor function is started.264Section 2-17Device Monitor FunctionNT31/NT31C ScreenData areaAddress Hexadecimal PV Binary PVASCII charactersWith the NT31/NT31C, the PVs of up to 3 words can be displayed simultaneously.NT631/NT631C ScreenData areaBinary PVHexadecimal PVAddressASCII charactersWith the NT631/NT631C, the PVs of up to 8 words can be displayed simultaneously.Data Area and AddressThese columns display the word address (data area acronym and address) ofthe words being monitored.
The table cells containing the word address act astouch switches; press either cell to change or clear the word being displayed inthat row.Hexadecimal PVThis column displays the PVs of the specified words in hexadecimal. The tablecells in this column also act as touch switches; press the desired cell to changethat word’s PV in hexadecimal. With timers and counters, the cells can be usedto set/reset the timer or counter.When a timer or counter is being displayed, a j will appear next to the hexadecimal PV when the timer/counter times out or counts out.Binary PVThis column displays the PVs of the specified words in binary with bit 15 on theleft and bit 00 on the right.
Force-set and force-reset status are also indicated.When the word’s PV is changed in hexadecimal, that change is also reflected inthis column.The table cells in this column also act as touch switches; press the desired cell tochange that word’s PV in binary or force-set, force-reset, or clear the forced status of bits in the word.ASCII CharactersThis column displays each PV as 2 extended ASCII characters. Spaces will bedisplayed if there aren’t ASCII characters equivalent to the PV.265Section 2-17Device Monitor FunctionSpecifying/Changing the Word and Clearing the DisplayWords Displayable in the Registration Monitor ScreenThe following table shows which words can be monitored in the registrationmonitor screen.DataareaNameCS/CJC200HX/HG/HE (-Z)C200HS, CPM1,CPM2A, CPM2C,CQM1, or SRM1CQM1HDMData Memory AreaOKOKOKOKIR/CIOInternal Relay orCore I/O AreaOKOKOKOKTIMTimer AreaOKOKOKOKCNTCounter AreaOKOKOKOKHRHR (Holding Relay) AreaOKOKOKOKARAR (Auxiliary Relay) AreaOKOKOKOKLRLR (Link Relay) Area---OKOKOKWRWork AreaOK---------EMEM Area (current bank)Installed EMbanksInstalled EM banks---Installed EMbanksEM0 toEMFEM Area (bank 0 to bank F)Installed EMbanksInstalled EM banks---Installed EMbanksOK: Can be displayed No: Not applicable Not with Host Link: Installed EM banks can be displayedThe CS/CJ-series PC’s Task Flags (TK) and clock pulses (P) cannot be displayed.ProceduresUse the following procedure to specify the word to monitor, change the word’sPV, or clear a word from the display.1, 2, 3...1.
Press the data area or address cell in the desired row. The following popupwindow will be displayed to input the word address. (This example showsthe NT631/631C.)If you specify a row in which a word is already displayed, that word’s dataarea and address will be displayed in the popup window.Reference:S Monitoring will stop in a row while the popup window is being displayed to inputa new word address for that row. Monitoring will continue in the other rows andany changes in those words will appear on the screen.S No other operations can be performed while the popup window is being displayed on the screen. (The PT can be controlled from the PC if the PT is operating.)266Section 2-17Device Monitor Function2.
Press the Up and Down Arrow Keys (Y and B) to select the desired dataarea. The following table shows the order in which the data areas appearwhen the Down Arrow Key is pressed. (The data areas appear in the opposite order when the Up Arrow Key is pressed.)PC modelData area orderCS/CJ, C200HX/HG/HE(-Z)DM → IR/CIO → TIM → CNT → HR → AR → WR→ EM* → EM0* → ... → EMF* → clear → (repeatfrom DM)C200HS, CPM1, CPM2A,CPM2C, CQM1, SRM1CQM1HDM → IR → TIM → CNT → HR → AR → LR →clear → (repeat from DM)DM → IR → TIM → CNT → HR → AR → LR →EM* → EM0* → clear → (repeat from DM)* The number of EM banks depends upon the PC being used. The PT will displayonly those EM banks available in the connected PC.Select clear for the data area to clear all of the cells in the row.3.
Specify the address by pressing the Increment and Decrement Keys (+ and–) on the word address’s thumbwheel switch. (This step isn’t necessary ifyou are clearing the row.)The digit will be incremented or decremented by 1 each time that you pressthe Increment or Decrement Key.4. Press the Write touch switch. The PT will begin monitoring the specifiedword in the row and the popup input window will be closed. (The row will becleared if clear was selected for the data area.)If the specified word address is not valid, an error message will be displayedin the lower-left corner of the screen and the buzzer will sound.
(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 address in that row.Changing HexadecimalPVs and ForcingTimer/Counter StatusUse the following procedure to change a monitored word’s PV in hexadecimal.This procedure can also be used to force-set, force-reset, or clear the forced status of timer/counter Completion Flags.Reference: If the timer or counter Completion Flag is force-set, it will be in time-out or countup status regardless of the PV. Likewise if the timer or counter Completion Flag isforce-reset, it will be OFF even if the PV is 0.1, 2, 3...1.
Press the hexadecimal PV table cell in the desired row. (Pressing the cellwon’t have any effect if a word isn’t being displayed in the row.)The following popup input window will be displayed.NT31/NT31C input windowNT631/NT631C input window267Section 2-17Device Monitor FunctionWhen the input window is displayed, the binary PV cell will change as shownbelow to receive the new hexadecimal PV.NT31/NT31C:“From > jjjj To > ????”NT631/NT631C:“From > jjjj To > ????”• The jjjj field shows the original PV that was displayed when the hexadecimal PV table cell was pressed.• The ???? field displays the new PV as it is entered.Reference:S Monitoring will stop in the row while the popup input window is being displayed.
Monitoring will continue in the other rows and any changes in thosewords 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. Input the new word PV or specify the timer/counter’s new forced status.Changing a Word PVInput the new PV by pressing the hexadecimal touch switches (0 to 9 and A to F)on the popup input window. Each time that a digit is pressed, it will appear in the???? field in the binary PV table cell.
The digits are input from right to left.The following values will be displayed as the five keys 3 → 5 → C → 8 → A arepressed: 0003 → 0035 → 035C → 35C8 → 5C8A.The new PV field can be returned to 0000 by pressing clear.Force-setting and Force-resetting Timer/Counter Completion FlagsSpecify force-setting or force-resetting by pressing the corresponding touchswitch in the popup input window.ActionTouch switchDisplay after changeForce-settingSet or Force-setSETForce-resettingReset or Force-resetRESETClearing a Timer/Counter’s Forced StatusSpecify clearing the forced status by pressing the corresponding touch switch inthe popup input window.ActionClearing forcedstatusTouch switchRelease or Force-releaseDisplay after changeClearing force-set status:PV (0000)Clearing force-reset status:PV before force-resetIf the Clear touch switch is pressed, the force-clear operation will be cancelledand the PV will be returned to its previous value.3.
Press the Write touch switch. The new value will be written to the word in thespecified row, the hexadecimal PV, binary PV, and PV character will changeto match the new value, and the PT will restart monitoring. At the same time,the popup input window will be closed.If the new value cannot be written, an error message will be displayed in thelower-left corner of the screen and the buzzer will sound. (This buzzer soundcan be disabled with the PT’s touch switch sound setting.) In this case,check the status of the PC and specified data area and try changing the value again.
