Dear Community,
We have recently expanded our portfolio with the modern IEC 61850 communication standard. This standard is widely used in power systems, primarily for communication between Intelligent Electronic Devices (IEDs) and other components within electrical substations.
The IEC 61850 standard facilitates information exchange throughout the entire substation. For real-time communication at the lowest Process Level, the GOOSE and SV protocols are used. For communication towards SCADA, the MMS protocol is utilized. The B&R PLC can serve as an IED or MU (Merging Unit) in the substation.
Key Features
IEC 61850 offers significant advantages over its predecessors like DNP3 and IEC 104:
- GOOSE protocol is used instead of hard-wired signals (like tripping a breaker).
- Sampled Values (SV) protocol replaces hard-wired analog signals.
- A consistent naming convention for signals and data objects.
- SCL (System Configuration Language) is used to describe the configuration of the substation and its parts.
- Additional information is available in the B&R Online Help.
Requirements
- Requires 1x license 1TC61850.00-00 per controller. This is a fair-use license.
- The protocol is implemented using the Cp61850 library.
Example
The Getting Started section of the Cp61850 library help provides a step-by-step description of how to create a sample IEC 61850 server with GOOSE protocol support.
Q&A
- What version of AS is supported?
- The library can be used in both AS4 and AS6.
- What targets are supported?
- The library can run on any B&R PLC.
- Can a client be implemented using the library?
- Client support will be added to the library in the next update.
