  41. Nomenclature • Protocol: A common set of rules to govern the exchange of data between nodes on a network. • It determines: • Initialization of data link • Services that are supported • flow control • Frame format and sync • error control

  42. Communication Protocols and Standards Messaging Services • Provides “Common Services” for communicating information • including notification of delivery or non-delivery of a message • and the reason why not • Types of services: • -Initiate Communications • -Identify • -Define Data • -Write Data • -Program Invocation • -Etc. • Existing Standards: FMS, MMS, DNP, IEC Data Communication Hierarchy

  43. Communication Protocols and Standards • Manufacturing Message Specification (MMS) • Internationally standardized messaging protocol for real time exchange • of data and supervisory and control information between networked • devices. • ISO 9506 standard • Independents from the application function being performed • Independents from the developer of the device or application • Generic to be appropriate for a wide variety of devices and applications: • PLC • Robot • Protective relay • Based on the OSI model MMS services and messages are identical

  44. Communication Protocols and Standards MMS Service Specification • Defines a set of objects that can • exist within a device. • Defines a set of communication • services to access and manipulate • those objects. • Defines the behavior of the device to those communication services. Data Communication Hierarchy

  45. Communication Protocols and Standards MMS Services • Get Object • Change Object • Determine Attributes • Create Object • Delete Object Data Communication Hierarchy
