I want to modify it temporary, the programs like this, the target is M91.3 & Q6.7 . I want to keep the variables target is true although the input changed. |

Hi, with S7-300 and Simatic Manager you can also use triggers. Please check manual chapter 20.7 Modifying Variables and 20.8 Forcing Variables SIMATIC Programming with STEP 7Regards,Towome

Hi
Your project is written in simatic step7 v5.5 And you want to use tia portal v13 and v14? Try to migrate a STEP 7 V5.x project to STEP 7 Professional (TIA Portal) , of course you need step7 v5.x to migrate. Make sure you have secure backup and proceed with another copy. Regards Hosein |

@Hosein: Good health to you. I do not agree with you. Going to TIA just because Step7 V5.5 is unfamiliar, is not the answer. I see in this topic already two people who are making helpful suggestions in keeping with Step7 V5.5. Changing from Step7 Classic to TIA may have other consequences. The idea is to change as little as possible when troubleshooting / testing. @Febryn: Good day. Have a look at the document that Towome suggested. Chapter 20.8. This will work to force the output. I would not recommend this as it can cause problems if you are not aware of what you will influence. Writing a value to M91.3 is problematic.. regardless which version of Step7 you use. Manipulating the bit in VAT will write the value only once. There after the bit will be modified back to what you show in the program. Making program changes as part of trouble shooting is acceptable for some cases.. as has been said before in this topic. ~ |

so there's no ways to keep value M91.3 hold on its position, right? |
