ISA-106 TR1 Terminology

Here are some of the definitions being proposed in the first of the three technical reports being written by the ISA-106 committee as groundwork for developing standards for Procedure Automation for Continuous Process Operations.

Automation style – a consistent approach to developing and deploying implementation modules.

Implementation Module – the developed and deployed result of implementing procedure and control requirements in a BPCS.

Procedure automation – Implementation of a procedure on a programmable mechanical, electric, or electronic system.

Procedure – a specification of a sequence of actions or activities with a defined beginning and end that is intended to accomplish a specific objective.

Procedure requirement – the definition of what is required to accomplish an objective using a procedure.

Process state – a definable operating condition of process equipment as it progresses from shutdown to operating and back to shutdown. Each process state represents a unique operating regime that supports the process equipment’s objectives of processing an input into a desired output.

State-based control – a plant automation control design based upon the principle that all process facilities operate in recognized, definable process states that represent a variety of normal and abnormal conditions of the process.
