Status Button
Purpose
The Status button is an operating and display element with the two states
ON and
OFF. Status buttons indicate the status of a device which cannot be determined
from the operating unit (e.g. a motor). At the same time, it is also possible to
change the status of the device concerned on the operating unit.
Configurable properties
The behavior of the Status button can be configured:
Option
switch:
The Status button reacts as a toggle switch. Each time it is operated, it
switches to the other status and remains in that status until the button is
pressed again.
In addition to the tags, which represent the current switch status, the
configuration software can be used to define text or graphics for the two
statuses
ON and OFF.
Option
push button:
The Status button reacts as a key-in button. When pressed, the Status button
changes to the status
ON. It remains in this status as long as the Status button
is pressed. When released, it automatically switches back to
OFF.
Event-related initiation
Use the configuration software to assign the Status button one or more functions
and to define which events result in the respective function being triggered. The
events which can be configured are:
Changed
This function is triggered as soon as the status of the Status button changes.
OnButtonDown
This function is triggered as soon as the Status button changes to the status
ON.
OnButtonUp
This function is triggered as soon as the Status button changes to the status
OFF.
If the status of the Status button changes from the type
switch due to a
modification of the configured variables, none of the described events is triggered.
