Free IEC 61850 and 104 protocol traffic capture tools called “Observer”.
An interesting development for the IEC 60870-5-104 and 61850 protocol analyzers is that in 2006 support for free capture tools is implemented. KEMA offers this “Observer” capture tool which can be used to capture IP based traffic on a number of sites. This “Observer” capture tool has the following features:
- Capture IP based IEC protocol communications and store these in log files
- Cyclic Buffering functionality, saving log files for example if specific and configurable situations occur (Link
initialization, errors, etc.)
- Remove old log files in order to prevent running out of disc space. The trigger to remove old log files is configurable
to for example: time, size of Log files, remaining disc space
- Display single line protocol communications, for expanding the frames a full version analyzer is necessary
- Configure the protocol parameters and capture filter settings
- Easy to install and does not require a hardlock key in order to function
- Runs on Windows 2000 and Windows XP The 2006 versions of UnIECom 104 and UniCA 61850 analyzers can open
the log files stored by the Observer.
Existing clients just need to renew their Service Level Agreement (SLA) for the analyzer to enable this option. Advantages of this system are that an unlimited number of free capture tools can be used (for example each support and field engineer) and only a limited number of the full version analyzers are necessary for the detailed automatic analysis
