No error display

Unable to change screens.

When changing screens directly via T tag,
	<Direct Access Method>
	Set the word address to [LS8]. Also set [Set 16 bit] for an operation mode and enter a screen number to change for a constant. Check that the coordinates of SW go along the touch panel grid.
	<Memory Link Method>
	Set the word address to [15]. Also set [Set 16 bit] for an operation mode and enter a screen number to change for a constant. Check that the coordinates of SW go along the touch panel grid.
	<In Memory Link Method, Screen Change by using Interruption with T tag>
	Set the word address to [13]. Also set [Set 16 bit] for an operation mode and enter 20 to FE for a constant. (Do not use 00 to 1F.) When the touch is pushed, the set constant data is output from GLC to the HOST. The screen data to change is written from the HOST side to the address, [15] by the output data. Check that the coordinates of SW go along the touch panel grid.
	<Screen Change via both the HOST side and Screen Touch>
	When you change screens via both the HOST side and Screen Touch, it’s necessary to clear the screen change address on the HOST side so that the screen change from the HOST side is not affected by the screen change via touch.
	Check it with [Screen Change] of [T tag] of Tag Reference Manual.
Check the display screen number data format.
	Set the display screen number data format of GLC.
Screen Change via the part, Special Switch.
	When Interlock is set, turn ON the bit of the interlock address.
Hierarchy Screen Change of T tag.
	When Hierarchy Screen Change is checked, Hierarchy Definition is executed. In order to enable this feature, it’s necessary to set Enabled for [Hierarchy Screen Change] on the [System Setting] tab of [GLC Settings].
Check Simulation mode
	Confirm that the mode is not Simulation. Go to Offline mode. Then if SIM-LINK is displayed left below of the screen, it’s Simulation mode. In transferring data, uncheck [Simulation Feature Setting (M)] of [Transfer Setting (S)] and then transfer data again.
Check the setting of Multi Link
	When Multi Link connection is set, the communication doesn’t start unless you turn on the bit responding to my station number from the PLC side to the address of the communication information set in [Station information setting].
