GI Poll Button
Requests a General Interrogation poll, which forces a connection to the PLC or RTU and requests that it send an update of all the data registers.
The IEC 60870-5-104 driver sends data on change, so if already connected, it can be assumed that VTScada is up-to-date. Pressing the button in this case will have no effect. This button is most often used for testing purposes.
The properties dialog for the GI Poll widget:
Tag
The Tag field displays the name and description of the IEC 60870-5-104 driver tag that is associated with this widget. You can use this to select a different tag or parameter to use as the data source for this widget.
Button Label
Use to change the label displayed on the button. May be useful to specify which IEC 60870-5-104 driver will be polled when pressed.
Disable Options
Disable selected operator-interaction features of this widget.
