HolonStationProbe 104
In developmentAct as the controlling station on IEC 60870-5-104. Connect to RTUs and gateways, interrogate them, send commands and read every ASDU in a log that makes sense.
Planned features
What this tool is being built to do. Features may change before the first release.
Link control
Open connections, start and stop data transfer, watch test frames and tune the k, w and timeout parameters.
Interrogation
Run general and counter interrogation, globally or per group, and see the full image of the station.
Commands
Send single, double and regulating step commands and set points, with select and execute or direct execution.
Clock synchronisation
Send clock sync commands and check the time stamps the outstation returns.
Readable ASDU log
Every frame decoded with type identification, cause of transmission, IOA, value, quality and CP56Time2a time tag.
Point list check
Import the expected point list and flag missing, unexpected or wrongly typed points.
Where it helps
End-to-end signal tests
Check every point between the station and the control centre side, one by one.
Control centre mapping
Verify addresses and types before the link to the real control centre goes live.
Communication troubleshooting
See exactly what the RTU or gateway sends, and when.
