IEC 61850 Integration Into Beckhoff PLC

Beckhoff - a well known German PLC manufacturer - successfully offers IEC 61850 modelling, configuration, and information exchange for IEC 61850 and IEC 61400-25. 

Excerpt from their website ... worth to read:

"Application example: 

In this case, the use of IEC 61400-25 [mapping according to IEC 61400-25-4 IEC 61850-8-1, MMS] enables all wind turbines from different manufacturers in a wind farm to communicate with a central station.

Standardization avoids the use of vendor-specific protocols, which would lead to increased application expenditure. BECKHOFF supports this method with the implementation of IEC 61850 or IEC 61400-25 respectively in the TwinCAT Automation suite."

Beckhoff has a very nice and easy to read (and understand) online documentation.

Click HERE (English) and HERE (Deutsch) to find the details of the implementation of Client, Server, GOOSE Publisher and Subscriber.

Just give it a try.

Are IEC 61850 based Systems Cyber-Secure?

Often you hear arguments that IEC 61850 based systems are not cyber-secure ... is that true?

The truth is: The standards series IEC 61850 refers to the standard series IEC 62351. Example:

Power Systems Management and Associated Information Exchange – Communication network and system security – Part 4: Profiles including MMS and derivatives

IEC 61850-8-1 (Mapping to MMS) requires to use TLS ... as defined in IEC 62351-6 !!

Another issue to protect your IEC 61850 based system is to monitor the traffic and compare it with the configured communication relations and contents:

There is a lot of activities going on to increase the cyber-security in automation systems.

New Book on IEC 61850

Please note that there is a quite new book (400+ pages) about IEC 61850 for electric power systems:

IEC 61850 Principles and Applications to Electric Power Systems

Editors: Peter Bishop, Nirmal-Kumar C. Nair

Click HERE for details.

The basic approach of the IEC 61850 standard series is to some degree independent of electric power systems and applicable in most automation domains.

Example: Monitoring of a process measurement

The following sketch shows an excerpt of a series of presentations I conducted recently.

A instantaneous measurement (in IEC 61850 xxxx.instMag) can be read at any time by some computer (on the left). The value could come with a quality information saying: Value is ok; and a timestamp.

Instead of polling the value, you may want to receive the value every 10 seconds automatically without polling. Next you may want to receive the value when it changes by +/- 10 % compared to the last reported value. Or you may want to receive a report in case the quality of the value changes from good to bad ... and so on.

IEC 61850 information exchange services for monitoring process values offer many additional possibilities to receive spontaneously sent information. The information to be sent can represent measurements you find in building automation, heating systems, diesel generators, pressure systems, car manufactoriing, ...

Click HERE for papers co-written by Nirmal-Kumar C. Nair (co-author of the new book) and myself (Karlheinz Schwarz). You will be surprised what we published more than 10 years ago! (some papers may not easily be accessible! ... sorry for that).

Stay tuned to the blog to see more on this in the future. 

IEC 61850: Communication Interfaces for Mobile Battery Energy Storage Applications

A. Bonetti ... NO, NOT Andrea Bonetti, but his son Alessandro wrote a very remarkable Master Thesis at KTH, School of Electrical Engineering and Computer Science (EECS) (Stockholm, Sweden):

Communication Interfaces for Mobile Battery Energy Storage Applications

Alessandro, Congratulation! Excellent!

You wrote: "Then, I give my sincere appreciation to Karlheinz Schwarz for answering my questions regarding modeling, and maintaining an open blog with comments and thoughts regarding power system automation."

You are welcome!

Excerpt from the Abstract:

"This thesis project, carried out at Northvolt Systems, aims to analyze the existing and readily used communication interfaces for a specific set of mobileBESS applications. The analysis is performed by a literature review of typical mobile BESS applications with the identified corresponding communication interfaces. Among the identified interfaces is the IEC 61850 standard, which shows suitability in smart grid applications, enabling interoperability,vendor-independence, and standardization. To provide a real-life analysis of the IEC 61850 benefits and applicability to mobile BESS, an integration of the standard to a Northvolt mobile BESS was performed."

UPDATE On My Personal Situation After My Wife Passed Away On October 25, 2022

Dear All,

You may remember my post dated October 24, 2021: 

https://blog.nettedautomation.com/2021/10/some-information-about-my-personal.html

One year and one day later:

My wife Ingeruth passed away on October 25, 2022 after a long lasting and serious illness at the age of 69. Ingeruth suffered ALS which was diagnosed in January 2017. One of our daughters and I nursed her 24/7 since then. She needed air ventilation all day and night … and electric power 24/7 …

I really miss my wife ... 

I have been contacted by several people that asked me, if I would be available for some consultancy work or training ... and even travel again. During the last years I have done training and consultancy work by phone and online ... YES, I am available ...

I also hope to spent some time to post useful information on this blog.

Note that I am planning to attend the DistribuTech 2023 in San Diego (Febr 7-9).

Ingeruth and I planned to travel to San Diego in January 2017, six years ago. But the doctors told us on January 6, 2017 the diagnosis ALS … we cancelled the trip immediately. So, I am now catching up (alone) on what we missed to do together … 

Please contact me in case you have a question ...

How To Bring Plant Engineers To The Table When Cyber Issues Are Discussed?

In my career as electrical and IT engineer I have experienced that engineers are quite often not invited to discuss the measures and plans for critical infrastructure protection with IT personnel.

It is completely different compared to the world of electric power system protection - I mean the applications of protection relays. Protection engineers are (in my understanding) the most crucial engineers. They are very important for the reliable delivery of electric power. Protection engineers are likely to attend any meeting when it comes to the reliability of the power flows. Protection engineers know what to do ... software people may help to implement the "what" and the IT personnel may help to solve the communication issues ... but the crucial parts are dominated by protection engineers!

Mr. Vytautas Butrimas, a globally well known engineer involved in cyber security of control systems has briefly discussed the "Berlin wall" between IT personnel and plant engineers.  

Click HERE for the four page paper written by Mr. Butrimas.

Either of the groups involved believes that his or her group is the center of universe. There is little communication between the IT personnel and the engineers. 

There are so many semipermeable walls between, e.g., politicians, company lawyers, economists, IT experts, and plant engineers. There is usually no way that experts from any layer are allowed to talk to the experts from the other layers. In the end: Each layer feels independent of the other layers ... which leads to what we see these days ... and may be even more in the future. Have you heard of a discussion between a power protection engineer and a lawyer or even a medical doctor?

It would help medical doctors to understand the basics of electric power system reliability ... and so on. Because medical doctors (and all other people of a society) depend 100% on available power.

So in the end: (Electrical) Engineers should be honored by the society ... the problem may be that the engineers are not wearing white coats but wear safety boots, safety helmets, goggles,  protective gloves, ... a single doctor may harm a few people ... a protection engineer may harm millions of people during a blackout caused by a misconfiguration of protection equipment.

How Does Time Impact Our Life?

 I remember well the discussion on understanding and using UTC Time in IEC 61850 ... a very time consuming discussion. There are still discussions going on ... should UTC be replaced by something else?

Whatever format and scale you are using or inventing ... you will see problems over a longer period of use.

These days we see even cars may have crucial issues with processing of time:

Honda, Acura cars hit by Y2K22 bug that rolls back clocks to 2002:

The report starts with: "Honda and Acura cars have been hit with a Year 2022 bug, aka Y2K22, that resets the navigation system's clock to January 1st, 2002, with no way to change it."

True? Yes, it seems to be true.

A well known issue is related to the year 2038: Year 2038 problem

Many other time formatting and storage bugs!! 

Use the time you have in 2022 to spent more of it for or with your family, friends, ... stay safe in 2022!

Happy new year! 

Lesson learned: Don't expect that more automation, more programs, more smart phones, ... give you any additional time in your life! I guess they will consume a lot of your free time to find and fix bugs of many kinds ...

Power Outage In Frankfurt Area (Germany) - And People That Need A Breathing Ventilator

I just read that in the western part of the city Frankfurt (Main, Germany) the electric power was down for more than 10,000 customers. A current transformer (CT, for measuring the current) blow up ... and produced a lot of smoke. The power went off from 17:15 on Tuesday 2021-10-26. The restoration took some eight hours!

The Hessenschau (de) reported that nine (9!) people that depend on breathing ventilators had been hospitalized. This critical situation tells us, that the ventilators did likely not have battery backup power - either in the devices or external. The devices we use for my wife have both two internal batteries which give (rated!) power for 16 hours for each device.

This brings two questions up in my mind:

1. Why is it not required by law that all breathing ventilators have battery power for at least 24 hours?
2. Why don't we have to have external batteries and inverters that would give power for several days?

Instead of bringing patients with the ambulances to the hospital, it would be much easier (faster and cheaper) to bring an emergency power supply package (batterie plus inverter) to the patients! Or?

There seems to be a wide area of improving the quality of life.

By the way, why did the CT (current transformer) crash? Was it too old or not ... or? I hope that my friend Andrea Bonetti (one of the most experienced protection engineers on this planet) will comment on the importance of CTs!

Any comment?

Add on (2021-10-30): 

First: The utility has told that more than 100 workers are involved in fixing the problem ... the current fix is provisionary only! 100+ workers means: It must be a big problem that needs so many people to fix. 

Second: It was reported that in an elderly care home the nurses had to use their mobile phone's flash light to look for the elderly people ... no emergency light! Hmm ... strange. A few 12V batteries and some 12V LEDs would have done a good job! Cheap and useful ... lifesaving! ... if somebody would care for their maintenance. The management has obviously decided to purchase a hand lamp per floor ... 👍 something is better than nothing. Note: A battery leak (AA or AAA batteries) may damage a flash light that is not used often ... or only in case of emergency. Non leaking batteries are available: Lithium Batteries are the right choice for emergency devices. I have replaced the typical AA and AAA batteries with Lithium batteries for all flashlights and outdoor devices like thermometer ... they withstand cold weather and do not leak ... life time likely 10+ years ...
