Motorola GT10 KEY POINTS, If the screen does not change as expected

GT10/GT30 7.1 Switching Screens

For information on setting the auto–paging function, please see page 78 (GT10) and page 100 (GT30).

If using this function, please be aware that 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 the contents of the first word (the screen number specified by the PLC) do not change. For detailed information, see page 120.

Clicking on the button displays the value setting dialog box shown below. Specify the number of the screen to which the display is to be changed.

KEY POINTS

If the value is entered with the button pressed as shown at the left, a hexadecimal screen number is speci- fied, and if the value is entered with

the button pressed, a decimal value is entered.

The button acts as a backspace key when entering an address, and the button functions as a Clear key.

If the screen does not change as expected

If the screen is changed from the PLC, and the GT main unit function switch parts are also used to change the screen (Change Screen operation mode), a case sometimes occurs in which the screen does not change, even though an instruction to change the screen has been issued by the PLC.

Example: Screen No. 1 is displayed in keeping with the instruction from the PLC, and the screen is changed to Screen No. 2 using the function switch parts.
