Power Meter, SIMEAS P 7KG7750/55, Manual
E50417-B1076-C375-A3, Release 01.2009
2.2 Functional Range
This chapter describes the functional range which is supported by the IEC 60870-5-
103 slave interface of the SIMEAS P50 device.
2.2.1 Basic Application Functions
Table 2-1 Basic application functions
Clock
synchronization
The accuracy of the internal clock of the SIMEAS P50 with clock synchronization via
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.
IEC 60870-5-103 function
Supported by
SIMEAS P50?
Remark
Station Initialization yes
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.
General Interrogation yes
Refer to table 3-4 for a list of events which are con-
tained in general interrogation.
Clock Synchronization yes
Using the individual IEC 60870-5-103 device address
or the broadcast address.
Command Transmission yes
Commands to additional modules (binary output,
relay output) and to onboard binary output.
Test Mode no
SIMEAS P50 can not switch to Test Mode.
The function is not applicable.
Blocking of Monitoring Direction no
As in the case of Test Mode, this is a function which is
not supported by the SIMEAS P50.
Transmission of Disturbance Data no -
Generic Services yes Used for write of parameter (Analog Output module).
