Each GOOSE includes time information on the duration of validity of its
information. This corresponds to the double time period to the next GOOSE
repetition. If the duration of validity has elapsed without having received this
GOOSE again (i.e. because of a fault in communications), the signals received
will automatically be set to their respective default value
[IC]: Default Input Value. Which of the possible state values will set the
wanted security grade is dependent on the relevant application.
The following configuration (shuttling to the device functions) of the logic state
signals received from the logic node GosGGIO1 (GOOSE: Input 1 fct.assig.
(or Input 2, …, Input 128)) is made on the basis of the selection table of the
binary signal inputs (opto‑coupler inputs).
The virtual key "Unmap" may be used to remove the link of a binary signal input
to an external data point. In such a case all entries for this binary signal input are
deleted.

Fig. 3-19: Uniqueness of Control.
If with a system application it must be ensured that only one control command at
a time is being processed system wide (“uniqueness”) then interlocking of
secondary devices among themselves is setup with GOOSE. The P634 sets the
status information Control/LLN0.ST.OrdRun.stVal. when it has received a control
command. This information – stored in a dataset – is distributed in the system by
GOOSE and is therefore available to all other devices as an interlocking
condition. The state information is reset and accordingly signaled after
termination of the command sequence.
The P634 is capable to monitor the command status of up to 32 further devices.
With the IED Configurator OrdRunGGIO1.ind1.stVal to OrdRunGGIO1.ind32.stVal
are configured in a similar way to the other GOOSE inputs. A shuttling to the
interlocking equations is not necessary as their consideration within command
checking is automatically enabled when the first binary signal input is configured.
During a signaling receipt phase command effecting will be rejected.
