IM151-8 PN/DP CPU - DP master problem

Hi everyone,

I hope that someone can give me a hint about this issue.

I have inserted DP master into the IM 151-8PN/DP CPU and it seems like it is not recognized. No LEDs are lit (No power, No SF, o BF).

Can anyone tell me a reason for this maybe? Screenshot in the attachment.

Thank you!

Hello,

check Diagnostic buffer or upload it here as txt file. Look to your screen, something with CPU and DP module cfg problem. With my quick insert HW as same types, no problem. Maybe you have not enough I/O, maybe other problem...

Hi Duris_I,

Diagnostic buffer in the attachment. But I think that those error messages are not related to this problem. And I have noted that also last element in the rack has the same problem (8 DO card - you can't see it on first screenshot becuse i didn't expand rack when I made a screenshot ).

Hello,

pls attach more zipped screenshots. I recommend check address collision, maybe you mix some areas together also. I still think that buffer can maybe point to this problem. There is some clear info about mismatch so check all addresses on modules to not have collisions with other.

Thank you for helping me.

In the end I have deleted HW config and made a new one....and problem was gone.
