Adjustable IEC_103 serial communication parameters are shown in the table
below.
Parameter
Unit address 1...254
Baud rate 9600, 19200
Function type 0...255
Scale factor 1.2 or 2.4
Frame type 0...17
RTD data frame
0 or 1
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
IEC_103 station address
Communication speed
Unit function type
1)
Analog value scale factor
Measurement frame type
If RTD data frame is on, it is sent to
class 2 data poll every second.
Explanation
Address of the RET 54_ in the DNP
3.0 network. Must be the same as
configured in the master station.
Address of the master station
(destination address for unsolicited
responses). Must be the same as
configured in the master station.
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.
Number of retransmissions on data
link layer when RET 54_ sends
spontaneous data.
This timeout is used when RET 54_
sends messages with confirmation
request. The timeout must be set
according to communication speed.
Number of retransmissions on the
application layer when RET 54_ sends
messages with confirmation request.
Enable/disable confirmations on data
link layer.
Enable/disable confirmations on
application layer.
