  • ADS-net (Autonomous Decentralized System network) is one of the open industrial real-time networks according to ISO/IEC 8802-3 and is based on the ADS technology defined in ISO 15745-4 – Industrial automation systems and integration – Open systems application integration framework.
  • ADS-net was developed in Japan by the members of the MSTC (Manufacturing Science & Technology Center), consisting of users, vendors and academics. MSTC has been promoting standardization activities such as MAP, Field network and ADS-net technology since 1985.
  • ADS-net has incorporated recent evolutions in network technology-such as advanced priority control, and autonomous re-configuration and communication-developed in collaboration with organizations such as IEEE ISADS (International Symposium on Autonomous Decentralized Systems, established in 1993), as well as IPv6 technology.

Evolution of ADS-net technology and standardization

The ADS-net protocol has been open to the public since 1999, and it was standardized as ISO 15745-4 in 2003.
This latest ADS-net specification was approved as IEC/PAS 62953 (Publicly Available Specification) in 2014. Soon after the IEC’s approval of this PAS in November 2014, the Japanese national committee submitted an NP (New work item Proposal) of the technology to the IEC.
