The ISA Standards and Practices Department is aware of the growing need for attention to the metric system of units in general, and the Internat
8、ional System of Units (SI) in particular, in the preparation of instrumentation standards. The Department is further aware of the benefits to USA users of ISA standards of incorporating suitable references to the SI (and the metric system) in their business and professional dealings with other count

This page intentionally left blank. 13 ANSI/ISA-95.00.06-2014 INTRODUCTION This ISA-95 Part 6 standard is based on the use of ISA-95 object models defined
30、 in ISA-95 Parts 2, 4 and 5 (Parts 1 and 3 do not contain object models) to define a set of services that may be used to exchange information messages. It is recognized that other, non-Part 6 sets of services are possible and are not deemed invalid as a result of this standard. This Part 6 standard
31、defines a Messaging Service Model (MSM) for exchanging data exchange messages in a publish/subscribe mode and a request/response mode. It defines a minimal interface s ubset to message exchange systems. The Messaging Service Model provides a method for applications to send and receive messages from
32、MSM service providers without regard to the underlying communication mechanism, as part of a complete application-to-application communication protocol. This Part 6 standard defines a set of services definitions that are designed to provide the functionality needed for a vendor-independent method fo
33、r sending and receiving data exchange messages on a message exchange system, such as an Enterprise Service Bus (ESB). The knowledge requirements to interface to just one message exchange system can be immense, and are usually not transferable to a different system. MSM defines a single interface, in
34、dependent of the underlying services, for Level 3-3 and Level 4-3 communications. This removes the need for vendors to build custom interface after custom interface, and for end users to get locked into a single vendor because their investment prevents them from reusing any of the integration effort
35、s. Enterprise-control system integration involves multiple different steps to exchange data between different computer system applications, as shown in Figure 1. a) The applications usually have different internal representations of exchanged objects in their own local data stores. This representati
36、on is usually converted from the local format to a commonly accepted global format. The ISA-95 Part 2 standard defines representations of a global format for Level 4-3 data exchanges. The Part 4 standard defines representations of a global format for Level 3-3 data exchanges. This conversion, from l
37、ocal to global and global to local, is usually performed twice for any two-way communications. EXAMPLE 1 Assume two applications, ALPHA and BETA: the ALPHA application initiates a data exchange with the BETA application, and BETA responds back to ALPHA. The format conversions are: AL HA c f b f f h
38、qu d , b f BETA c format for the requ d , BETA c f b f f h p d , d b f AL HA f f h p d . b) Conversion must be performed to align the namespaces among the exchanging applications, and is usually performed four times for any two-way communications. EXAMPLE 2 Names for elements of data may be codes, t
39、ag names, or equipment identifiers. EXAMPLE 3 Data which are represented in one element namespace, such as codes 1,2,3,4, may have a different namespace in another application, such as codes Ok, Done, Error, Delay. c) Once information is in the global format with appropriate global names, the exchan
40、ged information is sent from one application to another application. d) Messages are transported from one application to another, either within the same computer environment or across computers. Transport mechanisms are defined in other standards, such as TCP/IP and Ethernet standards. e) When data
41、exchange information is received, there are specific rules that define what resultant data are to be returned. The transaction rules are defined in the ISA-95 Part 5 standard.
