Hello Everyone,

I hope you all are doing great. I mostly work around Micro800 - CompactLogix controllers and have few questions regarding this.

1. Can we use ethernet protocol to connect to Micro820 and Micro850 controller? Is there any specific protocols we have to use?
2. What is the difference/features between Micro820-Micro850 and Micrologix controllers in regards with the connectivity?
3. Can we pull information from CompactLogix controller to Micro850? I need to monitor one tag/signal from CompactLogix -> Micro850. Is this possible? OR we have to use similar model PLCs for this?

Please give your inputs to the above questions and feel free to suggest any alternate solutions you may have.

Thanks in advance,
Maitrey Pandya
