− Status information commands for setting / deactivating the “information status” for
the information value of an object:
− Controlling activation of binary input status
− Blocking binary outputs
6.22.2 Steps in the Command Sequence
Safety mechanisms in the command sequence ensure that a command can only be
released after a thorough check of preset criteria has been successfully concluded.
Additionally, user-defined interlocking conditions can be configured separately for
each device. The actual execution of the command is also monitored afterwards. The
entire sequence of a command is described briefly in the following:
Check Sequence • Command entry (e.g. using the keypad on the local user interface of the device)
− Check password → access rights
− Check switching mode (interlocking activated/deactivated) → selection of
deactivated interlocking status
• User configurable interlocking checks that can be selected for each command
− Switching authority (local, remote)
− Switching direction control (target state = present state)
− Zone controlled/bay interlocking (logic using CFC)
− System interlocking (centrally via SICAM)
− Double operation (interlocking against parallel switching operation)
− Protection blocking (blocking of switching operations by protective functions)
• Fixed commands
− Timeout monitoring (time between command initiation and the beginning of the
execution can be controlled).
− Configuration in process (if setting modification is in process, commands are
rejected or delayed)
− Equipment not present at output (if controllable equipment is not assigned to a
binary output, then the command is denied)
− Output block (if an output block has been programmed for the circuit breaker, and
is active at the moment the command is processed, then the command is denied)
− Component hardware malfunction
− Command in progress (only one command can be processed at a time for each
circuit breaker or switch)
− 1- out of -n-check (for schemes with multiple assignments, such as common
ground, it is checked whether a command has already been initiated for the
affected output relay).
