I’m having a problem with discovering the AI’s and BI’s from a T3-BB controller. AV’s, AO’s, BV’s and BO’s are all discovered with YABE with no problem but the AI’s and BI’s show up with this error “ERROR_CLASS_OBJECT: ERROR_CODE_UNKNOWN_OBJECT”. Any idea what may be causing this?
It looks like YABE is trying to read AI:256 and BI:256, which are well beyond the valid range. The T3 controllers support up to 64 AI and BI points at most, so anything beyond that will return an “unknown object” error.
Could you let us know which firmware version you’re currently using?
We recommend updating to the latest firmware and T3000 software to ensure full compatibility and proper BACnet support.
I did update the T3000 software before this happened. I had saved the .prog file before the update and after I had this problem I reloaded the .prog file I had saved and everything came back to normal. Thanks for getting back to me.
