You used the Nesting option to isolate the timer so that the signal from the (A I0.0) is not terminated by the timer. Very kind of you |

Yes the parenthesis "(" and ")" does isolate the contents in the sense you understand. It has the same functionality as with math functions. Talking about "isolation" there exists all sorts of pitfalls however. [code] A I0.0 L MW10 T MW12 [/code] .. regardless of what the value of I0.0 is, the LOAD function will be executed. The code should be something like.. [code] A I0.0 JCN next L MW10 T MW12 next: NOP 0 [/code] If you are really into using STL.. Read this topic [LINK] --- TIA Portal is software Siemens has develop as a general engineering framework. Two of the more common components are Step7 and WinCC. Step7 for TIA Portal will replace Step7 V5.x. TIA Portal with Step7 Basic and WinCC Basic is used by people that only design for S7-1200 PLCs and Basic panel types. Step7 Professional handles the newer S7-300 and S7-400 as well as their replacement S7-1500. Not all S7-300 / 400 PLCs can be engineered with TIA Portal. More details as to this subject is beyond the scope of your thread. know however there is much to be said on the TIA Portal subject. That is all from me for now.. Greetings. w |

Thanks for that! VKE >>> RLO >>> Result of Logic Operation Example.. [code]Network 1 A I0.0 A I0.1 Network 2 A I0.3 = Q0.0 [/code] Q0.0 will come on when I0.0 and I0.1 and I0.3 is ON, because the RLO state in network 1 is not "terminated" in a coil. The same can be true when using a jump function.. but some jump function can change the RLO state. IBN-Service , did I translate your statement correctly? Thanks. w |

..added is an example of results that can carry over the network boundary. >> be careful on how you code your STL. w |
