Functionality of the Recorders in SENTRON PAC5200
The recorders are capable of recording both measurands and events in parameterizable time intervals. The
following recorder types are used in SENTRON PAC5200:
• Measurement recorder: recording of PQ measurands (acc. to IEC 61000-4-30) and non-PQ measurands
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 RMS values
• Fault recorder: Recording of sampled values of voltage and current using programmable triggers.
• Event recorder: recording of voltage events, frequency events, and voltage unbalance events
The device features a 2-GB memory for storing the recorder data.
Communication
To communicate with the systems control and other process automation equipment, the device features an
Ethernet interface.
Ethernet supports the device parameterization, the transmission of measured data, counter values and
indications/events, and the time synchronization via NTP. The communication protocols are HTTP and
Modbus TCP.
Time Synchronization
During operation SENTRON PAC5100/5200 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 TCP 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 PC or notebook.
Internet Explorer 6 (or higher) is required for this purpose. Devices featuring a display offer a limited
parameterization function using the front softkeys.
