CFC Using the graphically supported design tool CFC for logic functions in DIGSI

mation can be logically combined. Command outputs can be derived from the output
of logic functions. The link of the output of the CFC functions to the respective device
outputs is determined in the configuration matrix.
Passwords Only authorized personnel can perform switching operations. Switching operations
are protected by passwords.
Interlocking Command outputs may be subject to interlocking checks, which can be configured in-
dividually and graphically using the CFC logic too. Standard interlocking, such as
ground switch closed status indication, may be already contained in the basic settings
of certain device types when delivered from the factory.
Command Process-

are entered within the framework of the settings.
Event Recording All switching operations are recorded in the message list with date and time.
