Method and viewer for a cause and effect matrix in a safety system

摘要

A method in an industrial safety system for controlling a process or equipment. An industrial safety system comprises components with safety devices wherein the safety system enables signals to be generated as a result of an event or alarm. The method and system uses a cause and effect matrix with automated links between each event or alarm and an effect or an action to be taken upon receipt of the event or alarm signal due to the event. In an online view of the improved cause and effect matrix, at least one effect cell of the cause and effect matrix is arranged with a first executable link for a device represented by the at least one effect cell.

1. A method in an industrial safety system for controlling a process or equipment, said industrial safety system comprising components with inputs and safety devices and
wherein said industrial safety system uses control code generated by a cause and effect matrix with an automated link between each event or alarm and an effect or an action to be taken upon receipt of an event or alarm signal due to the event in one or more safety controllers, and wherein an online viewer provides an on-line view of said cause and effect matrix, characterized by providing at least one effect cell in an on-line view of the cause and effect matrix with a first control arranged to receive user input and provide an executable link for opening and controlling a device linked to the at least one effect cell, to operate the device directly from an effect cell it is linked to in the online view of the cause and effect matrix.
