OPC
Stop completely if already hidden:
The prerequisite for automatic stopping is, as already
mentioned, that the program window is not visible. Besides, the
program never stops itself in a situation where stopping
manually would result in a query. In other words, it stops
neither if there are still OPC clients connected nor as long as
there are unsaved changes to the device configuration.
5.8.6 Direct control from control panels
You can open a control panel for each server in the list which offers
essentially the same access possibilities as the OPC interface.
Click on the
Control
button in the
This device
area of the main
window.
The individual control elements are labeled with the names of
the corresponding OPC variables.
This is especially useful for familiarizing yourself with the behavior
of the terminal devices, and for example in the case of serial ports
to see the effect of the various filter options. This function does not
make as much sense however for true window control of the
devices, since you can not have more than one control panel open
at a time.
