6-1-5 Notifying the Display Screen to the PC

(To Display the Number of Currently Displayed Screen)

The following describes the processing to display the number of currently dis- played screen of the NT600S.

This processing reads the data from the PC status notify area.

To indicate that the screen has switched, use the screen switch strobe flag.

To display the number of the currently displayed screen, use the currently dis- played screen word.

When the screen has switched, the NT600S notifies the following to PT status notify area (PT to PC) allocated to the PC.

Screen switch notification:	Screen switch strobe flag of the PT status word
New screen number:	Currently displayed screen word

By reading the currently displayed screen word when the screen switch strobe flag has turned ON, the number of the currently displayed screen on the NT600S is displayed.

Screen switch strobe

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

The screen switch strobe bit reverts to OFF (0) after this is notified to the PC.

Reference Since the special auxiliary relays of the CV series PCs are allocated to thesystem, 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).
