Touch Switches
Reference: If there are multiple momentary touch switches on one screen that are allocated
to the same bit, and these multiple switches are pressed and released at the
same time, the OFF status will be notified each time the one of the switches is
released.
Set
When the touch switch is pressed, the notify bit comes ON, and it remains ON
after the switch is released.
Reset
When the touch switch is pressed, the notify bit goes OFF, and it remains OFF
after the switch is released.
Notes on Notification Operations
The manner in which touch switch notification is executed differs according to
the notification operation and communication method as follows.
When using touch switch input notification, note the following points.
• In the case of (1) in the table, the other bits in the same word are turned OFF by
• As shown in the example above, the only bits that are turned OFF are the ones
notification.
that were turned ON by processes other than PT operations, such as the lad-
der program or a Programming Device.
In the NT31/NT31C and NT631/NT631C, changes to bits by PT processes are
always reflected correctly so the momentary, alternate, set, and reset touch
switches can be allocated to the same word. (In the earlier NT30/NT30C and
NT620S/NT620C/NT625C PTs, the momentary touch switch could not be allo-
cated to the same word because the other switches’ operations would turn
OFF the momentary touch switch’s ON notification.)
