Dear Expert,

My Simatic S5-155U Cpu 948 In stop led is on.

When i connect my profibus cable to cp card CPU is going to Stop Condition after 13 or 14 seconds.
Stop light is slowly blinking.

When i unplug the Profibus cable from cp card. Make a Cold restart Cpu is on Run Mode. So i think Problem is not in Cpu But in Profibus Device.

So with comprofibus software i want to see what is the problem but i cant go to online in comprofibus software

Using Simatic Manager today i see the whole profibus network online.

I find problem in Address 14 and 15

Please see the image

So i change my module in address 14 & 15.
But Still Same Problem.

So i swap these address with 31 & 32
Now it is showing error in 14 & 15 again (ex 31 & 32)

In Hw Config i find that 14 & 15 are conneted differently via another profibus!!!!!!. (but they are connected in one profibus network in my machine)

Pls see the images
