Control panel for process connection

In the upper right corner of the user interface, the control panel for process connection can be found.
Please notice that this element do not signalize any status, it just provides the option to proceed with
disconnection/reconnection of signals and to set the automatic simulation of command responses
and reactions.
The actions carried out in this control panel have only effect on the signals which are displayed at
that moment in the grid, and not on the rest of hidden signals.
In the control panel, the user can select to disconnect or reconnect signals, and in which direction
(monitoring, controlling or both). See figure Fig. 50 and figure Fig. 51 depict this:
Figure 50: Process connection - direction
Figure 51: Process connection - value
When the appropriate direction and value are selected, the user must click on the "Proceed" button
to apply the changes.
Disconnecting signals in monitoring direction
When a signal is disconnected from process in monitoring direction, the RTU500 will block that
object's inputs, not sending them to the host system and not updating the RTU500 database with
the real value of the signal.
In the following example (Fig. 52), a SPI signal which belongs to a sub-device has been disconnected
from process in monitoring direction. Updates in the SPI's real value are blocked and not sent to the
host systems. Instead, the user can simulate the signal by means of the Test Mode user interface.
