Kalle Hello, Normally EN/ENO mechanism can be manually re-created by the programmer by jump functionality.Don't execute section A and alternatively execute section B.Moreover, in LAD those instructions are like contacts and you can put a controlling contact in series to govern the flow of binary logic. Hope that helps, Hamid Hosseini

I think you should read the following overview. Overview of the LAD elements Some instructions just can be contact such as comparators.They only has some effect on RLO.For functions developed by us or more complex instructions(Math function) you can think of such mechanism because trouble-free process of instruction is important.From information point of view, result of a comparison is TRUE or FALSE .No thing more.If you have snapshots of comparators with EN/ENO in older TIA versions, upload it here. In STEP 7, you may had an Enable signal that is made by AND logic.See the attachment. [code] U M 0.0 U( L MW 100 L MW 200 ==I ) = M 0.1 [/code] Attachment CMP.jpg (267 Downloads)

(see picture) Hello, For enabling and disabling EN/ENO option in TIA V12,Please check: Enabling and disabling the EN/ENO mechanism I don't have the newer version of TIA Portal to test but I think that it is not possible to have EN/ENO options here on IEC Timers.Test and update.About the library you are missing, if you edit a program for an S7 300/400, you can find them in category of extended instructions.
