Could you check in cross-references if this marker bitis used elsewhere (byte/word/doubleword instances)? Regards |

On the other hand, see this attachment. Only OB1 is present online on SIMATIC. Do I still need to check for cross references?

Hello krneki10 as for the problem in you first post (sr.jpg): Neither the SET nor the RESET input are true, but could it be that I 0.2 was ONfor >7 seconds at some stage? This would then SET (latch) M1.4 ON which of course would remain ON until such time that the RESET (I 0.1) becomes true. as for the problem in you secondpost (sr2.jpg): The SET as well as the RESET input are ON and the RESET one "wins" in the this case (as you aare using aSR Flip Flop, use a RS Flip Flop if you want the SET to "win",see also <F1> help on the SR and RS Flip Flops for more). I hope this helps |
Cheers |

Hello, I put CLR = M 1.0 = M 1.2 = M 1.6 = M 2.1 = M 2.2 to OB100. Is that correct? |

That doesn't work. When I switch from STOP to RUN-P mode, nothing gets resetted. |

They are all SR flip-flops and none is set to 1 by default. Please see my whole program attached. I already pasted what's in OB100.
