Examples 6.7.2 Programmable wiping pulse at falling edge Wiring diagram Circuit symbol Instruction list L I00.01 =N PP00.01 L PP00.01 = O00.01 Signal curve T = cycle time As opposed to the programmable wiping pulses of the previous examples, which were activated by a change of edge, the next two examples evalua- te the signal state. This influences the start-up behaviour. 108
