N- Feedback Tag: this feature is optional on most button-type objects (i.e. bit control,
change screens, write values, alarm buttons, etc.). If disabled, there is no visual
‘feedback’ that the button, when pressed, has performed its intended function (see
Toggle button #1 in illustrations). Therefore, the Appearance – Feedback Tag On
section determines what displays on the button.
Enable this feature and select the same tag for both the target address and the feedback
tag address, if you wish to see the button change state (i.e. go from an ‘off’ or
untouched look to an ‘on’ or touched look). Configure unique labels using the
Appearance-Feedback Tag Off/On sections (see Toggle button #2 in illustrations).
Alternatively, select a different feedback tag address to verify that some action has
taken place in the controller. The controller is then responsible for setting the feedback
tag bit, which will then cause the label on the button object to change states (see Toggle
button #3 in illustrations).
In the illustrations above, the three buttons along the bottom set bit B0 when pressed.
A lamp that represents the current state (On or Off) of B0 is directly above these
buttons. To the right of this lamp is the status of another bit, B1.
Button #1 is configured with no feedback. Notice that there is no change to how the
button looks regardless of whether or not B0 is On or Off.
Button #2 has feedback and both the target and feedback addresses are B0. This button
changes ‘state’ to reflect the current state of B0.
Button #3 has feedback as well but is using B1 for the feedback address. As a result, it
does not change state depending upon the value in B0. Rather, the look of this button
changes according to the value in B1, although the button controls B0.
a. Feedback Tag Address: the address read to determine which label state to
display.
b. Feedback Tag Name: Tag name assigned to the targeted tag address.
