SignalTap can tap two different types of signals, post-fitting and pre-shynthesis. Tapping post-fitting signals requires incremental compilation, which is not available in the Web edition.
Make sure the nodes you add to your STP file are pre-synthesis signals. You use the Node Finder filter to select "Signal Tap II: pre-synthesis".

It´s correct. But, is writen in datashet 14. Design Debugging Using the
SignalTap II Embedded Logic Analyzer that "The Quartus II software does not limit the number of signals available for monitoring in the SignalTap II window waveform display."
But when I choose another signal with right button of mouse over the signal or trying to add node(that doesn´t appear in the node list)
The option "Add Node to Signal Tap II Logic Analyzer" with the right button mouser of the signal appears disable for some signals. Why ??
We can´t use incremental compilation with web edition and because of that we can´t use post synthesis.
