Hi Ken, Check thisand figure-out how its protected [8)] Attached is a small STEP7 program with FC1 thatcalculates a + b = c. You download FC1 with copy/paste from SIMATIC Manager with offline/online blocks folder. Never change, save or downloadFC1in LAD/STL editor -> you will tripe the CPU (or wipeout the whole function). You can freely edit/download/test OB1 thoughor any other block. Dec AttachmentProt.zip (671 Downloads) |

Nobody figure out yet how FC1 works? Come on, there are no gimmicks, pure STL programming I swear. |

Didn't have CPU at that moment - couldn't check code execution. Surely worth rating^) |
