2.36.3.1 Functional Description
Checking a
Command Job
Please observe the following:
• Command entry, e.g. using the integrated operator interface
– Check password → access rights
– Check switching mode (interlocked/non-interlocked) → selection of de-interlock-
ing status.
• User-Configurable Command Checks
– Switching authority
– Device Direction Check (scheduled vs. actual comparison)
– Interlocking, Bay Interlocking (logic using CFC)
– Interlocking, System Interlocking (centrally, using SICAM)
– Double Operation Locking (interlocking against parallel switching operations)
– Protection Blocking (blocking of switching operations by protective functions)
• fixed command checks
– Timeout Monitoring (time between initiation of the command and its completion).
– Configuration in Process (if configuration is in process, commands are rejected
or delayed)
– Equipment available as output (if a resource was configured, but not allocated to
a binary input, the command is rejected)
– Output Blocking (if output blocking has set object-specifically and the command
is currently active, then the command is rejected)
– Module hardware error
– Command for this resource already active (only one command can be processed
at a time for a resource, object-related Double Operation Block)
– 1–of–n check (for multiple allocations such as common contact relays, whether
a command procedure was already initiated for the output relays concerned is
checked).
Command execu-
tion monitoring
The following is monitored:
• Interruption of a command procedure because of a Cancel Command
• Run Time Monitor (feedback indication monitoring time)
