Unexpected Ack in Event Viewer

[belias]

Hello,

 

I was looking at my event viewer this morning during a query, and I noticed the following "unexpected ack" events. Just wondering if anyone can shed some lights on these - what do they mean? Just a curiosity at the moment...

 

 

Thanks!

Hi bellias,

 

This usually happens when the PLM sends two ACKs instead of one. It's usually benign and happens most often with RF devices.

 

With kind regards,

Michel

Hi Michel,

 

Thanks for the explanation!
