initialized by activating the RESET input. In this case the outputs remain in their initial states until
release of the BLOCK input.

Reporting

The content of the counter can be read on the local HMI.
Reset of the counter can be performed from the local HMI or via the RESET input.
Reading of content and resetting of the function can also be performed remotely, for example from a
IEC 61850 client. The value can also be presented as a measurement on the local HMI graphical
display.

Disturbance report

12.4.1

Functionality

Complete and reliable information about disturbances in the primary and/or in the secondary system
together with continuous event-logging is accomplished by the disturbance report functionality.
Disturbance report DRPRDRE, always included in the IED, acquires sampled data of all selected
analog input and binary signals connected to the function block with a, maximum of 40 analog and 96
binary signals.
The Disturbance report functionality is a common name for several functions:
• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
The Disturbance report function is characterized by great flexibility regarding configuration, starting
conditions, recording times, and large storage capacity.
A disturbance is defined as an activation of an input to the AnRADR or BnRBDR function blocks,
which are set to trigger the disturbance recorder. All connected signals from start of pre-fault time to
the end of post-fault time will be included in the recording.
Every disturbance report recording is saved in the IED in the standard Comtrade format as a set of
three files comprising header file HDR, configuration file CFG, and data file DAT. Similarly, all events
are continuously saved in a ring-buffer. The local HMI is used to get information about the recordings.
The disturbance report files may be uploaded to PCM600 for further analysis using the disturbance
handling tool, or viewed online in the web HMI.
