8.3 Verifying the communication
To verify that the communication is working a test/analyzing tool, for example ITT600,
can be used.
Verifying redundant IEC 61850-8-1 communication
Ensure that the IED receives IEC 61850-8-1 data on the selected Ethernet ports. Browse
in the local HMI to
Main menu/Diagnostics/Communication/Ethernet status/Access
point/APStatusRedundant/RCHLCCH:1 and check that ChARedStatus and
ChBRedStatus are shown as Ok . Remove the optical connection to one of the Ethernet
ports. Verify that either signal status (depending on which connection that was removed)
is shown as
Error and the that other signal is shown as Ok . Be sure to re-connect the
removed connection after completed verification.
