Wednesday at Hannover Messe

Today (10 April 2013) was the busiest of the first three days. People … people, people walked the rows. Even more people than the other days stopped at the booth of TQ Systems, Beck IPC and SystemCorp. There was a huge interest in learning how to get IEC 61850, IEC 61400-25, IEC 60870-5-104, DNP3, Modbus … integrated into IEDs.


One of the most interesting questions asked today was from a small company that was looking for IEC 61850 software to be included for a substation switchgear drive system. The person I talked to said: IEC 61850 is very complex and we have figured out that the integration would cost some 100,000 Euro (one hundred thousand!) !! He asked me about my opinion.

My response was: It could be even more than 100.000 Euro – if you do it wrong! But it could be in the range of less than a tenth of that amount: some 5.000 Euro may be sufficient to get it running and integrated in the application … it all depends …

The Alarm Annunciator system developed by EES (Backnang, Germany) is one of the companies that recently implemented IEC 61850 within a few days … this integration proves that it is feasible in very short time.

EES presented a nice “power box” that promised that you reach the “finishing line” with IEC 61850 faster than without!



TQ System’s products were well received by many visitors.


Some companies were quite fast in immediately ordering the IEC 61850 stack/API solution during the fair – there is a lot of pressure in various markets to make smart IEDs speaking IEC 61850 and IEC 61400-25 … fast-to-market and at a reasonable price.

Dear Karlheinz:

I always smile when I hear someone say that ‘IEC 61850 is very complex’. So there are people who believe that their SAS implementations will be easier if they are based on other standards like DNP3 or IEC 60870-5-104.

If IEC 61850 is more complex than DNP3 or IEC 60870-5-104 it is only because it covers many more aspects of SAS engineering, namely the data model, a number of communication services that are not specified in other standards, and a configuration language. However, these aspects are ALWAYS present, no matter which standards you use. If you don’t use a standard that covers them, they will still be there, and they will be handled with in a non-standard way. It is very foolish to think that you are getting rid of e.g., the data model only because the standards you use do not contemplate the data model. Precisely what you will get is perhaps 20 different data models, one for each vendor represented in your SAS. Is this ‘less complex' than IEC 61850?
