Siemens 3.5 and5.6

Has anyone heard of service lab 3.5 and 5.6? This is the software for the s5 and s7 plcs for troubleshooting. Faster localization of faults
and better documentation also. You build your on monitoring programs
from scratch. Just something to throw out there for you beginners.

And where can you find it???????

Siemens

It is hard to find in usa. I have german equipment in plant and one technician had this software from one of the german companies. Siemens distributor should be able to obtain it for you.
