(a) What do you mean by cascading? (b) Why the understanding of sequencing of operation is necessary in automation?

 (a) Cascading is a methodological approach to the problems of pneumatic circuit design.

– Cascading mean (in series). In this method the sequence of pneumatic cylinder is controlled by using various types of signaling elements. These signaling elements are driven by forward and backward strokes of cylinder but the air supply to pilot line is delivered through cascade system.

(b) Sequencing of operation is necessary in automation because, there are often control situations where sequences of outputs are required, with the switch from one output to another being controlled by sensors.
