I have contributed to the MAP/MMS Standardization (Manufacturing Automation Protocols/Manufacturing Message Specification) from the very beginning. I was working for Siemens in the group dealing with communication solutions for process control and factory automation. In February 1985 I attended the first time a meeting of the MAP project at the GM TechCenter in Warren (Michigan, USA). As you can see, the first day was a very cold day (1985-02-14) with a lot of fresh snow:
I looked still young (40 years younger than today) ... 32 years old and father of four children.
The approach of MAP/MMS was very new ... even today a lot of people have difficulties with MMS ... especially because of using ASN.1 BER as the encoding notation for all messages exchanged according to IEC 61850 - Client/Server and Publisher/Subscriber messages!!
In 1993 I got also involved in the new IEC TC 57 project TASE.2 (Telecontrol Application Service Element 2) based on MMS ... called ICCP (Intercontrol Center Communication Protocol):
I attended the following meeting in Loveland (Colorado, USA):
30 years ago (March 1995) the IEC TC 57 decided to start a new project: IEC 61850 based on the EPRI UCA 2.0 Specification ... also using MMS/ASN.1/BER ... I got involved in UCA and IEC 61850 starting with the second IEC TC 57 WG 10 meeting end of 1995.
Many people in the electrical power world have complained since then that MMS/ASN.1/BER is toooo ... too much of ... and as a result many have departed from the approach.
I have suggested many times to use web services ... JSON encoding instead of ASN.1/BER and XML ... most people ignored the use of web services ... I guess it will come in the near future.
In many of the following standardization groups I have supported modern communication approaches ... in some cases it took some time ... or still is awaiting for a push:
