Hello, 

I have following configuration:

-CPU 416F-2 6ES7416-2FP07-0AB0

-CU320-2 DP 

I have problem with send data e.g STO, SS1 via PROFIsafe telegram 30 (I address 98..103, 98...103).If in CPU safety program i98.0 is set to true nothing change in diagnostic S_STW1 in Starter program. 

Standard telegram 1 works correctly for me, but i have problem with safety telegram.

For S71200F/S71500F is library LDRvsafe. Is something similar for s7400?

I have attached screens of my program configuration.
