LAN: Local area network

Nomenclature
Relay to Relay Com
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
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.
