Refer to Appendix DPC Memory Maps on page 441.The screen numbers that can be specified are as follows:BCD0000Hexadecimal00000001 to 3999 0001 to 0F9FScreenNo display (window closed)Window screen No. 1 to 3,999The X coordinates that can be specified are as follows:PTNT21NT31/CNT631/CBCDHexadecimal0000 to 0240 0000 to 00F00000 to 0300 0000 to 012C0000 to 0620 0000 to 026CContentsX coordinate of bottom-left corner(multiple of 20)NT21:0 to 240NT31/NT31C:0 to 300NT631/NT631C: 0 to 620The Y coordinates that can be specified are as follows:PTNT21NT31/CNT631/C66BCDHexadecimal0019 to 0139 0013 to 008B0019 to 0239 0013 to 00EF0019 to 0479 0013 to 01DFContentsY coordinate of bottom-left corner(multiple of 20 - 1)19 to 139NT21:NT31/NT31C:19 to 239NT631/NT631C: 19 to 479Areas for Control/NotificationReference:Section2-2S Local window can be also opened, closed or moved by the operation of touchswitch (page 310, 310).
In addition, by setting the attribute of the screen (basescreen) to be displayed, local window pops up at the same time the screen isdisplayed (refer to page 45).S Global window can be controlled only by writing to the window control areafrom the host.S Window position (coordinate) can be specified by 20 dot unit. (Y coordinate =multiple of 20-1, because of the bottom-left coordinate specification)Window can not be controlled and the contents of the window remains unchanged when the number other than multiple of 20 is specified for X coordinate or when the number other than multiple of 20-1 is specified for Y coordinate.However, when opening a new window, the window is displayed at the positionthat was specified when the window screen was created using the SupportTool.Functions of the WindowControl AreaIf the PT is currently operating, the status of the window is always written to thewindow control area.
The contents of the window control area depends on thewindow type (global window/local window) and the circumstances as follows:When the Window Is Opened by Touch Switch Operation (Local WindowOnly)A window screen that is set for a touch switch pops up at the position that wasspecified when the window was created using the Support Tool. At this time, thestatus of the window is written to the screen No.. X coordinate and Y coordinateof window control area (corresponding window type).When the Window Is Closed by Touch Switch Operation (Local WindowOnly)The screen No..
X coordinate and Y coordinate of window control area (corresponding window type) are all cleared to 0.When the Window Screen No. Is Specified for Screen No. of Window Control AreaThe specified window is opened as the corresponding window type. The windowposition follows the contents of X coordinate and Y coordinate of window controlarea. However, in the following cases, the window is opened at the position thatwas specified when the window was created using the Support Tool. (Windowmove operation is not performed and the X, Y coordinates return to the existingvalue when the incorrect X coordinate and Y coordinate are specified withoutchanging the screen No..)• When the contents of X coordinate is not multiple of 20, or when the contents ofY coordinate is not multiple of 20-1• When the window will extend out of the screen with the specified value (for example, when an NT31/NT31C is being used and an X coordinate of 300 and aY coordinate of 199 are specified for a window screen of 100 100 dots).When 0 Is Written to the Screen No.
of Window Control AreaWindow of the corresponding type is closed. The contents of X coordinate and Ycoordinate is retained.When the Screen Is Switched to the Other While the Window Is Being Displayed (Other Than System Screen)The behavior depends on the screen type as shown below. (Even when the global window and the local window were displayed before screen switching, theeach screen also behaves as the table below.

Themeaning of the data differs according to whether it is written from the PT or thehost.When the Data Is Written from the HostTo switch, open, close or move a window on the PT by an instruction from thehost, write the window screen number or coordinates to the window No.. X coordinate or Y coordinate as 4-digits BCD or hexadecimal. Whether the values areBCD or hexadecimal is determined by the setting for numeral storage type in thePT configuration settings made with the Support Tool.By changing the screen No.. window can be switched, opened or closed.It is possible to move the window position by changing the X coordinate and Ycoordinate.PTLocal Window1 opens(Window screen No.125)PCWindow control areaScreen No.Botom left coordinate (60, 99)68← 0125X coordinate← 0060Y coordinate← 0099Local Window1SectionAreas for Control/Notification2-2Screen No..

The PT clock data can be updated by updatingthe contents of this area from the host.The clock data area consists of 4 continuous words, as shown below. The firstword, j, is set under the Set Clock Address settings made with the Support Tool.15 14 13 12 11 10 9876543210BitWordjj+1j+2j+3Minutes (2-digit BCD)Day of month (2-digit BCD)Year (2-digit BCD)Always 00Seconds (2-digit BCD)Hour (2-digit BCD)Month (2-digit BCD)Day of week (2-digit BCD)Reference: It is not necessary to allocate words in the host for the clock data area when theclock data is not displayed or the screen display/alarm history is not used.69SectionAreas for Control/NotificationWords Allocated for theClock Data AreaSymbolC-series PCs2-2Words can be allocated for the clock data area (host to PT) in the following host(PC) areas.AllocationCV-series PCsAllocationCS/CJ-series PCsAllocationNoneIR AreaOKCIO AreaOKCIO AreaOKHHR AreaOK------HR AreaNot forHost LinkAAR AreaOKAuxiliary AreaNoAR AreaOKLLR AreaOK------LR Area*1Not forHost LinkTTC Area,Timer PVsNoTimer Area,Timer PVsNoTC Area,Timer PVsNoTU------------TC area,Timer Completion FlagsNoCTC Area,Counter PVsNoCounter Area,Counter PVsNoTC Area,Counter PVsNoCU------------TC Area,Counter Completion FlagsNoW------------WR AreaTK------------Task FlagsNoDDM AreaOKDM AreaOKDM AreaOKArea *2,EEMcurrent bankOKEM Area,current bankE0_ toEC_---------Not forHost Link---Not forHost LinkEM Area,current bankNot forHost LinkEM Area,EM banks 0 to CNot forHost Link*1: LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.*2: The EM Area is supported only by the C200HX/HG/HE(-Z)E PCs.The Auxiliary Area of the CVM1 and CV-series PCs is allocated to system functions, and cannot be used for purposes other than system use.The range of each memory area differs according to the PC.
