(I think in a deep volcano it would have a better place ratherthan in a factory...) My problem: 1, I have downloaded the example program that you'd programmed. 2, I changed only the PLC type to 1AD30 V1.0 3, I downloaded the whole project to the PLC 4, I opened the watchtable and loaded all modify values 5, STILL THERE IS 0 ONTHE OUTPUT VALUE (PLC is running) What should i do more?? thanks

And I must admit, that you solved my problem, butI do not understad this: 1, I download your sample program, make the PLC type change. 2, When I right click on the PLC in TIA portal, and choose "Download to device - > ALL" it isdownloaded but does not work.And itcan be monitored, the values of the variables can be changed (that is in myattached file). BUT 1, I download your sample program, make the PLC type change. 2, I rebuild all blocks 3, I right click on the PLC in TIA portal, and choose "Download to device - > ALL" it isdownloaded and works. I have never experienced suchstrange thingin S7-300 and Step7. Is there something like "autobuild" before downloading in it? And if it is, then why does TIA not have it? (I often feel in TIA that some developers have developed very good and usefull thing in Step7, and the new TIA developers does not care, do not use the ideas, starts everythingagain (and forget a lot to develope )) (a really simple example is the UNDO(ctrl+Z)REDO(ctrl+Y) when i delete a wholenetwork accidently) thanks for the help.

The rebuild all is a old history, not in STEP 7 but in WinCC flexible: in WinCC flexible the compile function was, in the first versions, to slow. So it was create a compile (that means delta donwload) and a rebuild all (that means entire donwload).The cause that "delta download"sometimes faults, I don't now...
