I'm using TIA Portal V11 SP2. Win 7 Pro. S71214 DC/DC/DC v2.2 DB S7-300 standart type there is no obsevation in System manual about it. That is a very inportant function, I think. Is the TIA Portal V11 SP2 really ready for S7300 use? The Simatic Step 7 v5.5 is faster, all functions working... Long Live to Step 7 v5.5 All the Best

But you should compile your complete STEP 7 program before. This function is also by S7-300. With best regards Cicero

So, it doesn't work. Regards. Attachment cross.jpg (528 Downloads)

If you want a work-around, you might be able to use the AT command to maybe address them like an array of bytes for cross-referencing. :( It is difficult using the new software with such high expectations! I expect it to be easier than it was in 1992 (on another vendor), yet, it is much more difficult in many ways to do the most rudimentary tasks (using TIA Portal/S7-1200).
