RET 54_
IEC_103
Adjustable IEC_103 serial communication parameters are shown in the table
below.
1) In REF 54_ and REM 54_: 160 = Overcurrent protection, in RET 54: 176 = Transformer differential
protection
2) Refer to Table 9.7.-1
The IEC_103 protocol is used for the optical serial communication network using
the RER 123 module connected to the X3.2 connector.
The unit address is used for identifying the device from the protocol point of view.
For more information, see Table 5.2.1-11 on page 93.

Explanation
Unit address
0...65532
1
Address of the RET 54_ in the DNP
3.0 network. Must be the same as
configured in the master station.
Master address
0...65532
2
Address of the master station
(destination address for unsolicited
responses). Must be the same as
configured in the master station.
Primary data link
timeout
100...10000 [ms]
1)
300
This timeout is used when RET 54_
sends data using service 3 (user data
with confirmation). The timeout must
be set according to communication
speed.

0
Number of retransmissions on data
link layer when RET 54_ sends
spontaneous data.
Application layer
timeout
1000...10000 [ms]
1)
1000
This timeout is used when RET 54_
sends messages with confirmation
request. The timeout must be set
according to communication speed.
Application layer
retransmission count
0...100

Number of retransmissions on the
application layer when RET 54_ sends
messages with confirmation request.
