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.
