Supervision of the Communication
A communication fault can occur in the following cases:
•
The connection between 2 SIPROTEC 5 devices is interrupted.
•
A hardware or software error is present in the device.
•
The supply voltage of one or more devices is not present.
If the receipt of GOOSE messages is disturbed, a GOOSE time-out is signaled and all GOOSE messages
incoming are signaled as
invalid
. If
No mode
is set in some of the devices, then the parallel control is not
blocked. If a communication error is present, the parallel mode in the Master and Follower device cannot be
determined. In this case, the operating mode automatic operation is blocked for safety reasons in the Master
and Follower device. Once the communication error has been cleared, the blocking is removed.
You can find more information about setting a GOOSE connection between the devices in the following
chapter.
Creating a GOOSE Later Binding for Parallel Control
To create the GOOSE later binding between the devices for parallel control, proceed as described in the
following example:
[dw_overview_sys-config_and_iec61850-goose, 1, en_US]
Figure 6-143 Example of a Parallel Control
Step 1
•
Create the 1st device for parallel control in the DIGSI 5 project.
•
Create the configurations and make the necessary settings for the IEC 61850 structure.
