IEC 61850 Server integrated in CODESYS Development System, Version 3.5 Service Pack 3 or later

3S-Smart Software Solutions GmbH (Kempten, Germany) has developed a CODESYS IEC 61850 Server that is completely integrated in the CODESYS Development System and provides implementation for users according to the first version of the standard.

Intelligent electronic devices (IEDs) according to IEC 61850 can be configured directly from the CODESYS Development System and employed as servers in energy networks. The configured servers render real generated data from the network units (IED) into messages and reports that can be used for further processing by connected IEC 61850 clients.

Minimum software requirements are:

• CODESYS Development System, Version 3.5 Service Pack 3 or later
• IEC 61850 server library adapted to the runtime system, in order to be able to use the SNTP

It is likely that IEC 61850 will be used more often in the factory automation and process control applications – because CODESYS is well known in these domains.

The Beautiful Simplicity of the Integration of IEC 60870-5-104 and IEC 61850

The experience has shown that manufacturers are still shying away from the high costs and long time required for the development of new products based on standards like IEC 61850, IEC 60870-5-104, and IEC 61400-25 (Wind Turbines) because the implementations and applications are quite complex.

For these reasons, a team at NettedAutomation developed a web-based integration tool based on Beck IPC’s com.tom WEB-PLC that significantly streamlines the application of these and other standards and the implementation of simple logic functions that consume and generate data communicated with a variety of protocols. The solution can be used to build various kinds of IEDs for monitoring, control, data concentrators, data aggregators, and gateways.

The com.tom with IEC 60870-5-104 and IEC 61850 are available – see the following website:

These standards are available on most com.tom … DNP3 is available soon. The programming with CoDeSys (IEC 61131-3) and C/C++ is also available.

Siemens reported using IEC 60870-5-104 for DEMS

Siemens DEMS 3.0 stands for third version of their “Decentralized Energy Management System”. It uses IEC 60870-5-104 for communication with power generators, storage devices or loads. The use of open communication and other solutions built-in reduce the engineering cost for virtual power plants by 60 percent – according to Siemens.

What could you do to apply the same cost reduction – or more – if you have to integrate IEDs that provide IEC 61850 information, information exchange and configuration language? Or how to connect a DEMS 3.0 system to IEC 61850?

Here is – I guess – the easiest and shortest time-to-market solution … without writing a single line of program code: The gateway using a so-called com.tom (communication to machine). The topology of an example is shown in the following figure. The gateway is implemented in the upper box.

All WEB PLC objects (inputs and outputs) related to IEC 61850 models are automatically generated from the corresponding SCL files. There is no need to do any manual configuration as long as you have the ICD files of the devices. The object names of the WEB PLC are derived from the object references of the IED/LD/LN.DO.DOA and so on. You see the path names in the I/O list.

All WEB PLC objects can be used to build applications like linking any input with any output (applying the same type – of course): single point input to single point output. The following diagram shows a simple gateway functionality to receive a command via IEC 60870-5-104, route it through an IEC 61850 client to an underlying IEC 61850 server that switches a fan on or off. The status of the FAN LN (using an extended Data Object OpSt) reports the status of the fan. This status is received from the underlying IED via an IEC 61850 report and routed to an IEC 61850 server and an IEC 60870-5-104 server in the gateway.

After “drawing” this diagram, all you need to do is to store the diagram to the gateway (com.tom Basic 3.1 S) and start the program. That’s it.

You may also have figured out the the com.tom Basic 3.1 S integrates an 5-port Ethernet Switch and another independent Ethernet port. This allows to build secure proxy servers/gateways.

The WEB PLC with IEC 60870-5-104, DNP3, Modbus, IEC 61850, … is a very easy, low cost and fast-to-market product that can be applied for many applications running on these communication solutions and for gateways. The application is freely configurable by drawing lines.

If you need complex functions, you can write them in C/C++ or IEC 61131-3 (CoDeSys) and wrap them for immediate use at the WEB PLC. For more complex applications you can program the application in C/C++ or CoDeSys and use the same communication.

Whatever protocol standard is used for a system (IEC 60870-5-104 for Siemens DEMS 3.0) you can easily integrate other devices that run DNP3, Modbus, IEC 61850, … with the com.tom WEB PLC gateway.
