(Same forwindow screen.) For overlapping screens comprising 8 child screens, themaximum is 256 per screen.There is no restriction on the number of touch switches that can be registered for one screen data file: any number can be registered as long as thedata file capacity is not exceeded. However, if a large number of elementsare registered, check that the restrictions on element display are compliedwith by referring to Display Restrictions (page 437).• When polygons are used as the display graphics for touch switches, one polygon can be given up to 255 vertices.• Up to 256 touch switches can be stacked together. If an overlapping area ispressed, all of the touch switch functions will be executed.
Except for functionscommunicating to the host, only one function can be executed at a time, so justSectionTouch Switches2-7stack one touch switch when stacking touch switches with functions other thancommunicating to the host. Touch switches that communicate to the host canall communicate notifications to the host at the same time.Common AttributesThe settings common to touch switches are indicated below.

Refer to Appendix DPC Memory Maps on page 441.When a DM Area or EM Area address is specified, add a bit number (00 to 15) tothe end of the word address.Reference: For touch switches for which the host notification function is set, a bit must beallocated for host notification in addition to the lamp bit and interlock bit.Display FunctionsAs with lamps, it is possible to set a graphic area for a touch switch that is displayed in different ways according to the status of a bit at the host. The bit at thehost that is allocated to control the touch switch display is called a lamp bit.The status of the lamp bit has the following effects.0 (OFF): Lamp is OFF1 (ON): Lamp is ON or flashingWhether the lamp is ON or flashing when the lamp bit is set to 1 (ON) is determined by the setting made for the On Type property of the touch switch.When a lamp bit is not allocated, touch switch performs only Show ON Statefunction.PTPCAllocated bit (touch switch 1)1 ←1ONTouch switch 1Like lamps, touch switches have four types of guide characters available: fixedcharacter string, ON/OFF switching, numeral display, or character string display.126SectionTouch Switches2-7Input FunctionsSwitch FunctionsThe touch switch elements of the PT are arranged in a grid measuring 16 wide by12 high on the screen.
