This chapter describes the functional range which is supported by the IEC 60870-5-
103 slave interface of the SICAM P 7KG7750/55 device.
Supported by
SICAM P 7KG7750/
55?
yes

The accuracy of the internal clock of the SICAM P 7KG7750/55 with clock synchroni-
zation via IEC 60870-5-103 compared to the clock of the IEC 60870-5-103 master is
±100 ms.
The SICAM P 7KG7750/55 automatically calculates based on the start and end dates
configured for the parameter Clock Change if the current date is summertime (day-
light saving time) or not.
Therefore, the SU bit in the Time Synchronization message in control direction is
ignored by the SICAM P 7KG7750/55 device.
The SU bit in the Time Synchronization message in monitoring direction is set accord-
ing to the internal summertime recognition of the current date.
Station initialization is necessary:
• After device start-up (power-up or reset) or
• After no telegram was received by the device for the
period of five minutes which is addressed to this
slave or is a broadcast telegram.
Refer to table 3-4 for a list of events which are con-
tained in general interrogation.
Using the individual IEC 60870-5-103 device address
or the broadcast address.
Commands to additional modules (binary output,
relay output) and to onboard binary output.
SICAM P 7KG7750/55 can not switch to Test Mode.
no
The function is not applicable.
As in the case of Test Mode, this is a function which is
no
not supported by the SICAM P 7KG7750/55.
no
Used for write of parameter (Analog Output module).
