Enabling Logic via
CFC
For the bay interlocking a control logic can be structured via the CFC. Via specific
release conditions the information "information released” or "bay interlocked” are
available (e.g. object "52 Close" and "52 Open" with the data values: ON / OFF).
Switching Authori-
ty
The interlocking condition "Switching Authority" serves to determine the switching au-
thorization. It enables the user to select the authorized command source. The follow-
ing switching authority zones are defined in the following priority sequence:
•LOCAL
•DIGSI
®
•REMOTE
The object "Switching Authority" serves to interlock or enable LOCAL control, but not
remote or DIGSI
®
commands. For the 7UM61 the switching authority can be changed
between "REMOTE" and "LOCAL" in the operator panel by password or by means of
CFC also via binary input and function key.
The "Switching authority DIGSI
®
" is used for interlocking or allows commands to be
initiated using DIGSI
®
. Commands are allowed for both a remote and a local DIGSI
®
connection. When a (local or remote) DIGSI
®
PC logs on to the device, it enters its
Virtual Device Number (VD). The device only accepts commands having that VD (with
switching authority = OFF or REMOTE). When the DIGSI
®
PC logs off, the VD is can-
celled.
Commands are checked for their source SC and the device settings, and compared
to the information set in the objects "Switching Authority" and "Switching Authority
DIGSI
®
".
