Hi,

anyway from my experiances it is simpler to create the programms in FBD. If you use normaly LAD the in the first view it looks easier for you, but at the end FBD is better (my experinces).

In the past I also started with LAD, but in a short time I changed to FBD and I still use FBD.

One main benefit is that every thing is complete if you "draw" the connection from one FB to another one. In LAD you need to "call" the Bit from the first FB connect it to the second, and then use the Bti from the second and connect to a coil. If this is on differnet possition then:
- simlutation
- online test
- investigation
is very complecated.

Hope this helps
