IEC 61850 Server
In Server mode inSCADA lets external IEC 61850 clients — a higher-level SCADA, a control centre, another IED — connect and read data from it over MMS.
Where it is used
Section titled “Where it is used”- Presenting data to a higher-level SCADA over IEC 61850 MMS
- IEC 61850 communication between separate inSCADA installations
- As a gateway in substation automation — presenting data gathered over other protocols in IEC 61850 form
Configuration
Section titled “Configuration”Connection
Section titled “Connection”| Parameter | Example | Description |
|---|---|---|
| Protocol | IEC 61850 Server | The protocol |
| Port | 102 | The listening port (for incoming connections) |
| SCL File Content | (the file) | The SCL file describing the data model to present |
The SCL file
Section titled “The SCL file”In server mode the SCL file describes the data model inSCADA will present to the outside world. It decides:
- which logical devices are presented
- the logical nodes under each one
- the data objects and data attributes under each node
Device, frame and variable
Section titled “Device, frame and variable”These are defined exactly as in client mode. The values of the variables you define are presented to the connected clients over MMS.
A typical deployment
Section titled “A typical deployment”Here inSCADA collects data from field devices over several different protocols and presents it upwards as an IEC 61850 MMS server. It is used above all in substation automation, to present data gathered from different manufacturers’ IEDs in one standard form.
