When the xecutes differences the differences instruction for OFF > ON, the soft component is changed to ON, and the ON - > ON - > OFF - > OFF - > ON - > OFF - > OFF. PLF instruction is a falling edge. These instructions are only one scan cycle. PLS and PLF are generally used as the output, LDP, and some of the CIS control instructions are generally used as a guide condition. Examples and details please refer to the QPLC public instruction manual 080814. Thank you
