Checking a Connection Using Direct Link
In case of an optical fiber link (as shown in Figure 3-27 or Figure 3-29) or via copper conductor link, this
connection is checked as follows:
•
Both devices at the link ends have to be switched on.
•
Check in the event log or in the spontaneous annunciations:
–
If the message
PDI FO con. to.
(protection data interface connected with no. 3243) is provided
with the device index of the other device in case of an optical fiber conductor, a link has been estab-
lished and one device has recognized the other.
–
If the message
PDI Cu con. to.
(protection data interface connected with no. 3244) is provided
with the device index of the other device in case of a copper connection, a link has been established
and one device has recognized the other.
–
The device indicates
Slave Login
, no. 3492 or
Master Login
, no. 3491 if the other device has
been detected.
•
In case of an incorrect communication link, the indication
PDI FO faulty
(no. 3230) or
PDI Cu
faulty
(no. 3232) is displayed. In this case, check the connection again:
– Are the connections correct and not swapped?
– Are the cables free from mechanical damage, intact and the connectors locked?
– Otherwise repeat the verification.
Continue with the margin heading “Consistency of Connection and Parameterization”.
Consistency of Connection and Parameterization
Having performed the above checks, the linking of a device pair has been completely tested and connected to
auxiliary supply voltage. Now the devices contact each other on their own account.
