LAN: Local area network

WAN: Wide 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.
