My ideawas to make a single function block,appropiate for my six sensors,so i could drag and drop it into my main routine six times (one for each sensor) and put them their correspondingsignals. Everything works fine for one sensor, but if I add more of them, mymain routineonly recognizes the values of the first function block. I must mention thatevery time I add the function block I'm writting about, the option multiinstance db doesn´t appear. Could that be my problem?I'm usingTIA PORTAL V11. Thanks!

If you call your sub routines from a OB, this feature is not avaliable. Suggestion, call all blocks from a FB, and this call this FB from OB1.
