C3rnash Posts: 18 Rating: (0)	how do I configure a timer included in the step 7 library to generate a pulse in an FB? I thought I could just use SFB4 "Generate an On-delay" and tie the output to a NC contact on the input. Why doesen't this work? When I simulate it with the NC at the input (addressed #temp1) it dosent examine for true even though the output (addressed #temp1) has a status of 0. Thanks Jarrett
