Figure 6-28 Display of Switching Authority and Switching Mode in Information Routing (in Function Block
General)
Sw. authority key/set and Sw.mode key/set indicate the current state of the key switch or parameter for
switching authority or switching mode and provide this information for further processing in the CFC. In the
CFC, for example, it is possible to set up an automatic routine to ensure that the switching authority is auto-
matically set to
Local
when the key switch is set to
not interlocked
.
The following table shows the dependency of the switching mode on the key-switch position and the
switching authority. In the case of switching commands from Remote, the information on whether a locked
or non-interlocked switching should take place is also sent. For this reason, the position of the key switch is
irrelevant for the switching mode in these cases. The information in the table assumes that, in the case of
remote switching commands or those from the station, the switching mode is
interlocked
in each case.
