Carrier CCN Communicating to a JCI/York Metasys System via Lon
I just looked at a new building today that had CCN stuff talking to a metasys control system through Lon. I pulled up everything on CCN, but it took forever to upload just 1 RTU. The network traffic from the Lon card is excessive. If I disconnect this card I can upload alot faster. Is it possible to reduce the network traffic or use a bridge to put the lon card on a secondary bus? As far as metasys goes I have never really worked on it. How can I learn more about this system? What software is needed to see all of the logic, and reprogram sequences? There is a few things that aren't working really good in there logic.
