Functionality of the Recorders
The recorders are capable of recording measured quantities, events, and load profiles in parameterizable time
intervals. The following recorder types are used:
Measurement recorder: recording of PQ measured quantities acc. to IEC 61000-4-30 (for example,
frequency, voltage magnitude, etc.) and non-PQ measured quantities (for example, currents, power, etc.)
over parameterized periods, for example, 10-second frequency, aggregation of voltage, current, power
etc.
Trend recorder: long-term recording and monitoring of the voltage change history over a parameterized
period of time in programmable tolerance ranges; 1/2 cycle RMS values
Fault recorder: recording of sampled values of voltage and current using programmable triggers,
maximum 256 samples per cycle
Event recorder: recording of maximum 256 frequency events and voltage-unbalance events each, as well
as voltage events of which the maximum counter depends on the memory configuration
Mains signalling voltage recorder: recording of mains signalling voltage on the supply voltage.
The device features a 2-GB memory for storing the recorder data.
Energy Management
As part of the energy management, SICAM Q100 records load profiles according to the Fixed Block and Rolling
Block method for all power quantities. Additionally, it is possible to calculate up to 6 tariffs (TOU = Time of Use).
The synchronization is made with external or internal triggers.
Communication
SICAM Q100 has an Ethernet interface and an electric RS485 interface.
Ethernet supports the device parameterization, transmission of measured data, metered values, load profiles,
and indications/events and the time synchronization with NTP. The communication protocols used are HTTP,
Modbus TCP, and IEC 61850 server.
The RS485 interface supports the transmission of measured data, metered values, load profiles, and indica-
tions and the time synchronization. The communication protocol is Modbus RTU.
The integrated Ethernet switch in the device allows cascading further network components (SICAM
subdevices) via a Y cable and integrating them in an existing network with IEC 61850 or another Ethernet pro-
tocol.
Time Synchronization
During operation SICAM Q100 needs the date and time for all time-relevant processes. This ensures that a
common time basis exists when communicating with peripheral devices and enables time stamping of the
process data. The following types of time synchronization can be executed:
External time synchronization via Ethernet NTP (preferred)
External time synchronization via fieldbus using the Modbus RTU communication protocol
Internal time synchronization via RTC (if external time synchronization is not available)
Parameterization
Parameters are set using an internal Web browser with HTML pages from the connected computer. Internet
Explorer 6 (or higher) is required for this purpose. Devices featuring a display offer a limited parameterization
function using the front softkeys.
