Abstract

Inter-operability of products connected together to form an industrial control system is determined by defining each product as a set of services describing points of interface between the products and by determining complementary services necessary for inter-operability from a table listing complementary services. A new product may be evaluated for inter-operability by comparing its services to services of products with which inter-operability is desired. In one mode of operation after definition of the products in which inter-operability is desired, a necessary list of services is compiled from a database and translated by a relationship map to complementary services which define a virtual product having the desired inter-operability. Inter-operability of an entire control system may be thus modeled prior to construction.

Dependent claims

A program implemented method for assisting in the design of inter-operable industrial control electronic products communicating on a common communication link, the products electrically communicating with other products via services defining points of interface between products necessary for the products to operate together using the common communications link, where each product treats another interconnecting product as a master, slave or peer, the program comprising:

a product database containing a list of industrial control products together with their associated services;
a service relationship map linking the associated electrical services to complementary electrical services where a service and its complement are necessary for two products to operate together using the common communications link;
instructions executable on an electronic computer holding the product database and the service relationship map in memory, the instructions to:
(a) receive from the user a list of industrial control products with which inter-operability should be maintained;
(b) search the product database of the list of industrial control products to develop a list of necessary services for the products of step (a);
(c) apply the list of necessary product services to the service relationship map to identify a list of complementary product services defining at least one inter-operable product that may operate with the products of the list using the common communications link;
and
(d) output a description of the inter-operable product.

(b) search the product database of the list of industrial control products to develop a list of necessary product services for the particular products of step (b);
(c) apply the list of necessary product services to the service relationship map to identify a list of complementary product services;
(d) for each particular product and for each other product which inter-operability should be maintained, search the product list for services on the list of complementary product services needed so that an industrial control product may operate with the other products with which inter-operability should be maintained using the common communications link;
and
(e) output an indication of the complementary product services not available from the other products.
