• Reset the interface parameters at the 7SD5 correctly:
• Disconnect the auxiliary supply voltage of the communication converter at both
• Reset the the communication converter to normal position (X32 in position 1-2) and
• Reconnect the supply voltage of the communication converter.
Perform the above check at the other end with the device being connected there and
its corresponding communication converter.

lowed by the device index of the other device, if interface 1 is applying.
– Message No. 3244 „PI2 with" (protection data interface 2 linked with) fol-
lowed by the device index of the other device, if interface 2 is applying.
– If the devices are at least connected once, the message No. 3458
„Chaintopology" will appear.
– If no other devices are involved in the topology as an entity, the message No.
3464 „Topol complete" will then be displayed, too.
– And if the device configuration is also consistent, i.e. the prerequisites for setting
the functional scope (Section 2.1.1), Power System Data 1 (2.1.2.1), Power
System Data 2 (2.1.4.1) topology and protection data interface parameters (Sec-
tion 2.2.2.1) have been considered, the fault message, i.e. No. 3229 „PI1 Data
fault" or FNo. 3231 „PI2 Data fault" for the interface just checked will
disappear. The communication and consistency test has now been completed.
– If the fault message of the interface being checked does not disappear, however,
the fault must be found and eliminated. Table 3-15 lists indications that indicate
such faults.

Meaning / Measures
„Device table inconsistent": the indexing of the devices is
inconsistent (missing numbers or one number used
twice, see Section 2.2.2.1)
„Device table unequal": the ID-numbers of the devices
are unequal (see Section 2.2.2.1 )
