6-1-4 Switching the Screen Display

The following describes the procedure used to switch the NT600S screen display by controlling from the PC.

Reference The display screen can be switched also by pressing a touch switch during the operation after registering a screen number to the touch switch. For this function, refer to the “Standalone Function” (page 141).

To switch the NT600S screen display by controlling from the PC, write a screen number at the “screen switch setting” in the PT status control area.

Screen number: 0000 (screen clear, no-display) 0001 to 01000

Reference Since the special auxiliary relays of the CVM1/CV series PCs are allocated to the system, they cannot be used for purposes other than the system use.

The range of respective area varies with the type of PC. Refer to Appendix L PC Memory Map (page 291).

Procedure 1. Use the support tool to allocate the PT status control area (PC to PT) to the PC memory.

2.Create a PC program to write the number of the displayed screen to the “screen switch setting word” in the PT status control area.

Reference Use a 4-digit BCD (binary-coded decimal) value to set a screen number.

If a screen has been switched by operating the PT status control area (PC to PT), the contents of the “currently displayed screen word” in the PT status notify area ￿(PT to PC) also change.

Screen switching timing

The NT600S screen switches when the contents of the “screen switch setting” have changed. To re-specify the number of the currently specified screen, first write the value 0000 to clear the screen before writing the appropriate screen number.
