I'm having some problems with a Trane MP581's lon communication with a JACE. For some reason, I keep getting send failures when I try to upload or quik learn it. The points are constantly cycling between fault and ok. The device never goes yellow and shows down, but in a verify report, it says the device is not communicating.
My workbench and the JACE match as far as modules go, so I've ruled out some type of issue from that.
I've checked the whole lon bus, and this field bus is as close to emaculate as you can get so I'm really leaning away from it being a physical network issue.
There are 22 devices on this network and this one particular controller is the only problem child. 3 of those 22 devices are MP581's with the exact setup as the one in question.
Has anyone had a similar issue they were able to work through?
