Manufacturing Message Specification

Manufacturing Message Specification (MMS) is an international standard (ISO 9506) dealing with messaging system for transferring real time process data and supervisory control information between networked devices and/or computer applications. The standard is developed and maintained by the ISO Technical Committee 184 (TC184). MMS defines the following

  • A set of standard objects which must exist in every device, on which operations like read, write, event signaling etc. can be executed. Virtual manufacturing device (VMD) is the main object and all other objects like variables, domains, journals, files etc. comes under VMD.
  • A set of standard messages exchanged between a client and a server stations for the purpose of monitoring and/or controlling these objects.
  • A set of encoding rules for mapping these messages to bits and bytes when transmitted.

MMS original communication stack

MMS was standardized in 1990 under two separate standards as

  1. ISO/IEC 9506-1 (2003): Industrial Automation systems - Manufacturing Message Specification - Part 1: Service Definition
  2. ISO/IEC 9506-2 (2003): Industrial Automation systems - Manufacturing Message Specification - Part 2: Protocol Specification
This version of MMS used seven layers of OSI network protocols as its communication stack:
Application Association Control Service Element (ACSE)- ISO 8649/8650
Presentation Connection Oriented Presentation - ISO 8822/8823

Abstract Syntax Notation (ASN)- ISO 8824/8825

Session Connection Oriented Session - ISO 8326/8327
Transport Connection Oriented Transport - ISO 8072/8073
Network Connectionless network - ISO 8348
Link MAC - ISO 8802-3 [Ethernet]

MAC - ISO 8802-4 [Token Ring]

Physical Ethernet

Token Ring

MMS stack over TCP/IP

Because the Open Systems Interconnection protocols are challenging to implement, the original MMS stack never became popular. In 1999, Boeing created a new version of MMS using Internet protocols instead of the bottom four layers of the original stack plus RFC 1006 ("ISO Transport over TCP") in the transport layer. The top three layers use the same OSI protocols as before.

In terms of the seven-layer OSI model, the new MMS stack looks like this:

Application Association Control Service Element (ACSE)- ISO 8649/8650
Presentation Connection Oriented Presentation - ISO 8822/8823

Abstract Syntax Notation (ASN)- ISO 8824/8825

Session Connection Oriented Session - ISO 8326/8327
Transport ISO transport over TCP - RFC 1006

Transmission Control Protocol (TCP) - RFC 793

Network Internet Control Message Protocol (ICMP) - RFC 792

Internet Protocol (IP)- RFC 791

Address Resolution Protocol (ARP)- RFC 826

Link IP datagrams over Ethernet - RFC 894

MAC - ISO 8802-3 [Ethernet]

Physical Ethernet

With the new stack, MMS has become a globally accepted standard.
