Manufacturing Message Specification

<h2 id="mms-original-communication-stack">MMS original communication stack</h2> <p>MMS was standardized in 1990 under two separate standards as </p> <ol><li>ISO/IEC 9506-1 (2003): Industrial Automation systems - Manufacturing Message Specification - Part 1: Service Definition</li> <li>ISO/IEC 9506-2 (2003): Industrial Automation systems - Manufacturing Message Specification - Part 2: Protocol Specification</li></ol> <p>This version of MMS used seven layers of <a href="/facts/OSI_protocols/MEEwuPY1">OSI network protocols</a> as its communication stack: </p> <table><tbody><tr><td>Application</td><td>Application Common Service Element (ACSE) - ISO 8649/8650</td></tr><tr><td>Presentation</td><td>Connection Oriented Presentation - ISO 8822/8823<p>Abstract Syntax Notation (ASN) - ISO 8824/8825</p></td></tr><tr><td>Session</td><td>Connection Oriented Session - ISO 8326/8327</td></tr><tr><td>Transport</td><td>Connection Oriented Transport - ISO 8072/8073</td></tr><tr><td>Network</td><td>Connectionless network - ISO 8348</td></tr><tr><td>Link</td><td>MAC - ISO 8802-3 [Ethernet]<p>MAC - ISO 8802-4 [Token Ring]</p></td></tr><tr><td>Physical</td><td>Ethernet<p>Token Ring</p></td></tr></tbody></table> <h2 id="mms-stack-over-tcpip">MMS stack over TCP/IP</h2> <p>Because the <a href="/facts/Open_Systems_Interconnection/oxN9Xhjz">Open Systems Interconnection</a> protocols are challenging to implement, the original MMS stack never became popular. In 1999, Boeing created a new version of MMS using <a href="/facts/Internet_Protocol_Suite/KNkxtSpw">Internet protocols</a> instead of the bottom four layers of the original stack plus RFC 1006 ("ISO Transport over <a href="/facts/Transmission_Control_Protocol/WW4sPrt9">TCP</a>") in the transport layer. The top three layers use the same OSI protocols as before. </p><p>In terms of the seven-layer <a href="/facts/OSI_model/oxN9Xhjz">OSI model</a>, the new MMS stack looks like this: </p> <table><tbody><tr><td>Application</td><td>Application Common Service Element (ACSE) - ISO 8649/8650</td></tr><tr><td>Presentation</td><td>Connection Oriented Presentation - ISO 8822/8823<p>Abstract Syntax Notation (ASN) - ISO 8824/8825</p></td></tr><tr><td>Session</td><td>Connection Oriented Session - ISO 8326/8327</td></tr><tr><td>Transport</td><td>ISO transport over TCP - RFC 1006<p>Transmission Control Protocol (TCP) - RFC 793</p></td></tr><tr><td>Network</td><td>Internet Control Message Protocol (ICMP) - RFC 792<p>Internet Protocol (IP) - RFC 791</p><p>Address Resolution Protocol (ARP) - RFC 826</p></td></tr><tr><td>Link</td><td>IP datagrams over Ethernet - RFC 894<p>MAC - ISO 8802-3 [Ethernet] </p></td></tr><tr><td>Physical</td><td>Ethernet</td></tr></tbody></table> <p>With the new stack, MMS has become a globally accepted standard. </p> <h2 id="external-links">External links</h2> <ul><li><a href="http://www.nettedautomation.com/standardization/ISO/TC184/SC5/WG2/mms_intro/">MMS Protocol Details</a></li> <li><a href="http://www.sisconet.com/wp-content/uploads/2016/03/mmsovrlg.pdf">MMS Overview</a></li> <li><a href="http://www.sisconet.com/wp-content/uploads/2016/03/mms_abstract_syntax.txt">MMS V1 Abstract Syntax</a></li> <li>MMS Protocol Description</li> <li>MMS.
