Fig. 5.1.13.-1 Communication port
1) Front connection for local communication
The relay is connected to a PC used for local parameterization via the infrared port
on the front panel. The front connection allows the use of the SPA bus protocol only.
The optical front connection galvanically isolates the PC from the relay. The front
connection can be used in two different ways: wirelessly using a PC compatible to
the IrDA
® ‚
Standard specifications or using a specific front communication cable
(refer to Section 7. Ordering information). The cable is connected to the serial RS-
232 port of the PC. The optical element of the cable is powered by RS-232 control
signals. The cable has a fixed baud rate of 9.6 kbps.
The following serial communication parameters are to be set for RS-232:
*
Number of data bits: 7
*
Number of stop bits: 1
*
Parity: even
*
Baud rate: 9.6 kbps
Relay data such as events, setting values and all input data and memorized values
can be read via the front communication port.
When setting values are altered via the front communication port, the relay checks
that the entered parameter values are within the permitted setting range. If an entered
value is too high or too low, the setting value remains unchanged.
The relay has a counter which can be accessed via

in the HMI menu. The counter value is set to zero when the
relay receives a valid message.
5.1.14. IEC 60870-5-103 remote communication protocol
The relay supports the IEC 60870-5-103 remote communication protocol in the
unbalanced transmission mode. The IEC 60870-5-103 protocol is used to transfer
measurand and status data from the slave to the master. However, the IEC 60870-5-
103 protocol cannot be used to transfer disturbance recorder data.
