(3) Interlocking-style indication
The button style indication during input of the interlock1 signal
helps the operator visually check the state of the button by
displaying the style that indicates the interlocking state. Since
both the interlocking style and on/off style are included, this style
requires more memory.
This interlocking style is specified in [Property] on the [Interlock
Image] tab.
There are several state indication check boxes for confirming the style
indication on the form. When all of these boxes are checked, the style
indications are prioritized as shown below. To confirm a
lower-priority style indication, uncheck the check box for a
higher-priority style indication.

CAUTION
When using a non-touch panel display unit, do not
use the momentary button attribute.
Even if the operator holds down the MDI key or soft
key assigned to a button, the key can be released
momentarily, depending on the state internal to the
display unit. Thus, a button operation such as for
signal output can result in chattering. Even for an
alternate button, chattering occurs while the key is
being held down, as with a momentary button.
