Check the Event Log (see also Subsubsection 7.1.1.2) or spontaneous annunciations
(see also Subsubsection 7.1.1.7):
Message 3217 " PI1 Data reflec " (PI 1 net mirroring ON) when you test protec-

tion data interface 1;
G
When working with both interfaces, note that the current interface of the 7SA6 is
connected to its corresponding communication converter.
G
If the message is not transmitted check for the following:
− - Has the 7SA6 fibre optical transmitting terminal output been correctly linked
with the fibre optical receiving terminal input of the communication convert-
er and vice versa (No erroneous interchanging)?
− - Does the 7SA6 device have the correct interface module and is it working
correctly?
− - Are the fibre optic cables intact?
− - Has the 7SA6 interface module "Light on" been set?
− - Are the parameter settings for interface type and transmission rate at the
communication converter correct (see above; note the DANGER instruc-
tion!)?
G
Repeat the check after correction if necessary.
Reset the interface parameters at the 7SA6 correctly:
Address 4502 CONNEC. 1 OVER = required setting, when you have tested protec-

tion data interface 1;
Disconnect the auxiliary supply voltage of the communication converter at both poles.
Note the above DANGER instruction!
Reset the the communication converter to normal position (X32 in position 1-2) and
close the housing again.
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.
Continue with "Consistency of Topology and Parameterization".
Having performed the above checks, the linking of a device pair, including their com-
munication converters, has been completely tested and connected to auxiliary supply
voltage. Now the devices communicate by themselves.
Now check the Event Log (see also Section 7.1.1.2) or spontaneous annunciations
(see also Section 7.1.1.7) of the device where you are working.

by the device index of the other device, if interface 1 is applying.
If the devices are at least connected once, the message FNo. 3458 " Chaintopol-

If no other devices are involved in the topology as an entity, the message FNo. 3464
" Topol complete " will then be displayed, too.

And if the device parameterization is also consistent, i.e. the prerequisites for set-
ting the function scope (Section 5.1), system data 1 (6.1.1), system data 2 (6.1.3)
topology and protection data interface parameters (Section 6.4.2) have been con-
