Hart Communication failure S800 IO over Modulebus
We have a configuration with AI9895 and AO895 used for HART communication over Modulebus. Tool routing is enabled in the controller. Transmitters connected to some of the IO modules work. However, there are other IO modules (Especially AI895) where i get status message as CONNECT TO HART DEVICE FAILED. When i select diagnosis on the AI895 Cards that is not working, i get following message
Operation in Progress: "RESET REBUILD"
Command response: "Device is busy"
I have read the DTM manual for S800, i understood what these messages meant but not how to solve it.
I have gone to service menut and tried to do a Master reset but this does not help.
Any advice from the experts in HART is deeply appreciated.
I assume it is 800xA/AC800M. Are you able to read 4-20 mA process values in CBM?
Also can you check position of AI895 modules in Property management aspect. Is it matching to what is there in CBM?
Check property management aspect of Modulebus also. Does it have controller IP address correctly defined?
