6.1.2 Switching the Screen with the GT Main Unit
Using the function switch unit
GTWIN has “function switching parts” (FSW0, FSW1, FSW2) in the parts library that can be used to
switch screens on the GT main unit. These parts should be arranged on the base screen and assigned
the attributes indicated below.
Function switching parts: Attribute editing dialog box
Double-clicking on the parts arranged on the base screen, or selecting a switch part, and clicking on the
“Parts (T)” menu and then the “Edit Attribute” sub-menu displays the dialog box shown above.
(1) Using the “Change Screen” operation mode
Select the “Change Screen” operation mode and specify the number of the screen to be changed. Then
press the switch part to switch the screen to the specified screen. To return to the screen displayed just
prior to the currently displayed screen, the “Return to Previous Screen” operation mode can be used.
Note:
In this case, the value of the third word in the basic communication area/word device (the number of the
currently displayed screen) changes to that of the new screen number, but please be aware that the
contents of the first word (the screen number specified by the PLC) do not change.
(2) Using the “Value Set” operation mode
Select the “Value Set” operation mode and enter the following settings:
- Data format: Specify 1 word
- Output destination: Specify to first word of basic communication area/word device
- Value: Number of screen to be changed to (hexadecimal specification)
Each time the GT main unit switch part is pressed, the screen number is forcibly written by the GT main
unit to the first word of the basic communication area/word device, and the screen is switched.
Note:
If using this method, the values for both the first word of the basic communication area/word device (the
screen number specified by the PLC) and the third word (the number of the currently displayed screen)
are changed.
