Hi, I have two problems related to operating "MotL", "MotSpdcL" and "Vlvs" blocks in PCS 7 V7.1 APL library 1- ) For Motor blocks ; When my SFC program executes "stop" command in automatic mode, "RdyToStart" output goes "0" for a few seconds and then goes "1" while all other intelocks are ok and conditions are satisfied. (I have configureted only one input for automatic start /stop in the chart type, this input is connected both "StartAut" and "StopAut" inputs, and the "StopAut" input is inverted. I also configured "Feature" parameters so that StartAut/StopAut should be countinuously on for operatio.(not pulse)) Print out of parameters for "MotL" block and screenshot of block - chart interconnection are attached. 2-)For VlvS block ; I am trying to configure so that when the block mode changes from Auto to manual or vice versa, the block should deactive output that opens valve(Control). Valve should not be open when mode changed.Print out of parameters for "VlvS" block and screenshot of block - chart interconnection are attached. the parametrization for "MotL" block mentioned above is working for changing mode, for example; when operator starts motor in manual mode and then changes mode to automatic, the motor goes to stop.
