"Display symbolic name of the access point" option:
To configure the time synchronization from an ES, you can also display symbolic names of
the access points that are represented by "<>". Activate the corresponding check box. When
the target computer boots up in runtime, these names are assigned to the access points.
If e.g. you use two access points with CP1623, the following modules are assigned to the
symbolic names using SIMATIC NET:
Symbolic name
<CP1623 (1)>
<CP1623 (2)>
The two internal tags "@TimeSyncDevice1State" and "@TimeSynDevice2State" are used for
the two access points. The tags are used in Runtime for diagnostics and displaying the status
of the access points. The settings are "Slave", "Standby master", "Active master" and
"Deactivated".
"Process controlling messages" option:
Process control messages are displayed in Runtime if synchronization problems occur. For
the process control messages 1012002-1012005, 1012018 and 1012021 you can set how
often the process control messages are to be displayed in Runtime in the "Process control
messages" field.
Activate the "Send once" check box to have the process control messages shown only once.
If you want to send the process control message several times in Runtime, deactivate the
"Send once" check box. Enter the desired value in the "Send every ... minutes" input field or
use the dial control.
