Method and system for automatically executing multiple procedures for a complex process facility
First Claim
1. A method of executing procedures for a complex process facility comprising:
- monitoring selected process conditions;
generating and storing a plurality of procedures each comprising a set of sequential steps at least some of which steps require verification of certain of said selected process conditions;
providing means automatically sequencing through and excuting said sequential steps of said procedures; and
providing an operator interface presenting to an operator a representation of said sequential steps as they are executed and means by which the operator can selectively assume manual control of selected procedures.

Abstract
A Supervisory Sequential Controller Interface (SSCI) provides for automatic and manual sequencing of the sequential steps of multiple procedures simultaneously in a complex process facility while preserving operator supervisory control over each procedure. The SSCI includes an Executive Interface which gives the operator global control over all of the procedures and a Procedure Interface which is arranged such that the operator may ascertain the relevant information about a particular procedure, including the mode (auto/manual), the current step being executed and the relevant states of plant components and parameters for the current step. Multiple Procedure Interface screens may be displayed to monitor/execute multiple procedures running simultaneously.
