Safety Matrix: intersections define the linking of causes and effects

Configuration of analog or digitalen causes and their digital effects

The matrix table is comparable with a spreadsheet program, and the configuration engineer first enters the possible process events (inputs) in the horizontal lines, and then configures their type and number, logical links, possible delays and interlocks, and any tolerable faults. In the vertical columns, he subsequently defines the reactions (outputs) to a particular event.

Events and reactions are linked simply by clicking the cell at the intersection of the row and column. Using these data, the SIMATIC Safety Matrix automatically generates complex, safety-related CFC programs. No special programming knowledge is required of the configuration engineer, and he can completely concentrate on the safety requirements of the plant.
