Abstract

A requirements database and test generator generates tests for functional and field testing and generates requirements documentation, user manuals, operational procedures, instrument data sheets, instrument indices, instrument loop diagrams, validation reports, and test reports, including exception and passing reports. A portable process control simulator (120) system which provides control system (900) users with scenarios that mirror field operation as defined.

Claims4

Dependent claims

A test system for testing a control system comprising:

a configurator having a set of tags, each tag being a label which corresponds to a component of the control system to be tested;
the configurator having a set of requirements wherein each requirement comprises at least one tag and at least one Boolean operator;
an I/O simulator;
and
a mechanism for automatically generating at least one set of instructions for the I/O simulator from each requirement, and a mechanism for transmitting the at least one set of instructions for the I/O simulator to the I/O simulator.
