I have a system pilot on a job that keeps coming unattached from the 6400 controller. It also just lost some of its configuration parameters. I was told that it could be interference/noise on the Comm. I was wondering what kind of things can be done to the CCN bus to prevent these problems? Should there be termination resistors somewhere on this network? Does Carrier have a RS-485 surge supressor available?
Thanks for the help.
