Explains the 'why' and 'how' relevant to the material included in ANSI/ISA-50.02, Part 3-1997 - Fieldbus Standard for Use in Industrial Control Systems Part 3: Data Link Service Definition, and ANSI/ISA-50.02, Part 4-1997 - Fieldbus Standard for Use in Industrial Control Systems Part 4: Data Link Protocol Specification. This technical report acts as a tutorial addressing those who are not familiar with ISA's Fieldbus Data Link Layer (DLL) documents.

The technical report is divided into two parts.

Part A

• presents the specific reasons why certain features in ISA's DLL documents are included;
• gives the essence of the documents' main features; and
• makes simple examples or graphic representation of such features.

Part B

• links separate parts of the ISA DLL documents relevant to either the same subject or to correlated items; and
• makes detailed examples of this DLL mechanism.

Scope:
To develop standards for signals used in process measurement and control, to transmit information between subsystems or separated elements of systems. Such signals may be analog or digital. However, data highway and other time-shared transmission paths, such as those within the scope of SP72, are excluded.

To continue to serve as the U.S. Technical Advisory Group for IEC-SC65A/WG4: Interface Characteristics.

Purpose:
To define a common interface between components of electronic measurements and/or control systems.
