	Important Points
	Type of Notification		When Using Host Link or	When Using C200H Direct
				Communication or NT Link with

				other than DM Area
	Momentary		(1)Notification in word units	(3)Notification in bit units
			(other bits go OFF)
	Alternate		(2)Notification in word units

	Set		are read on display and noti-	(4)Notification in bit units
	Reset		fication is based on this

When using touch switch input notification, note the following points:

-In the case of (1), the other bits in the same word as the notification bit are turned OFF by the notification operation.

Bit 15 14

0 1

Press the touch switch

1		0	Bit 15		14	1		0
	0	1		0	0		1	0
	Touch switch					Bits other than notify
	notify bit					bits are set to 0 (OFF).

- In the case of (2), notification is executed on the basis of the contents of the word before display, which means that the other bits are not rewritten. However, if the word contents are changed at the PC side, they will be rewritten based on the

	contents before display.
	- If the screen is switched while a momentary key is being pressed, the touch
	switch itself disappears, so the status “OFF” is notified. In the case of (1) this
	means that the other bits in the word will also be turned OFF.
	- When using the host link, or NT link with the DM area, do not allocate momentary
	touch switches and other types of touch switch to the same word, since the notifi-
	cation operations are different.
	In the case of (3) and (4), the notification operation has no influence on the other
	bits in the word.
Application	This example uses the touch switches as normal switches (bits) in order to use the
	NT600S￿	as an operating panel.
