IM151-1 issue

[Sango 113]

Hello Everyone,
Newbie on Siemens I get an issue with S7-314 connected to 2x( IM15-1 slaves).
In the program when 
--> I write (PIW) as input of FC105 the CPU switches on STOP, and BF LED turnes to red, RUN led & SF starts blinking
--> when I write ((IW) as input of FC105 the CPU switches on RUN, but the faults LED still red
diagnostic buffer of the Master is avaliable in the attached file.
i inserted a OB82, OB86 in the program and I have checked the physic link to the slaves ((it was working before))
Please if someone has the same issue, or know how can i resolve it 
Best regards

Hi Sango.

Are you writing to defined I/Q addresses?

From what I can see in your Diagnostic Buffer, you are experiencing IO Access errors, can you post your HWConfig? for the 2 IM151 modules and their respective devices.

Also remove the Calls in OB1, reset your CPU and check all diagnostic lamps go out (BF1, SF on CPU and LED on ET200). Let me know what happens

 

Regards
