Clock The accuracy of the internal clock of the SIMEAS P50 with clock synchronization via
synchronization IEC 60870-5-103 compared to the clock of the IEC 60870-5-103 master is ±100 ms.
The SIMEAS P50 automatically calculates based on the start and end dates config-
ured for the parameter Clock Change if the current date is summertime (daylight
saving time) or not.
Therefore, the SU bit in the Time Synchronization message in control direction is
ignored by the SIMEAS P50 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.

Supported by
SIMEAS P50?
Station initialization is necessary:
• After device start-up (power-up or reset) or
• After no telegram was received by the device for the
yes
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-
yes
tained in general interrogation.
Using the individual IEC 60870-5-103 device address
yes
or the broadcast address.
Commands to additional modules (binary output,
yes
relay output) and to onboard binary output.
SIMEAS P50 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 SIMEAS P50.
no
