Protection Testing with Client/Server Communication (MMS)

Client/Server communication is used for acknowledged point-to-point data transmission in IEC 61850 Digital Substations.
The station control or control center (SCADA, the client) sends a command to the intelligent electronic device (IED, the server). It gets a confirmation or a report back containing status information. Our Test Universe software uses the MMS protocol to obtain feedback from the tested IEDs.

Protection testing with IEC 61850 SCADA communication

After stimulation with secondary signals or MMS communication, Test Universe determines the reaction of the IED based on its data model and the reports sent to the control center. The device under test is automatically put into test mode and properly reset to normal operation mode afterwards.

Benefits of this solution

Full IEC 61850 data model access

Test Universe provides you with all available attributes in the data model of the IED. It unveils details which are not included in GOOSE messages or reports.

Verified transmission

Obtaining feedback from reports sent by the IEDs allows you to verify correct signaling to the control center at the same time.

Informative C/S monitor

The C/S monitor provides you with a list of all Client/Server transactions to analyze the communication activities in the network.

Easy configuration

Set up your tests efficiently with System Configuration Language (SCL) data. This speeds up the configuration and avoids errors.
