Hart Support to AC800M
Will 800XA ever fully support Hart I/O to the controller directly (AC800M) instead of having an AO forward data. Are there any new I/O modules that will support Hart variables to the controller other then replacing S800 with S900 I/O

Hi jday105,
I'm not sure what do You mean by "fully support HART". HART is digitally enriched 4...20mA signal, so it's more then resonable to support it with analog IO modules that forward this signal to controller, don't You think? As to the other part - sorry, but there are no other HARTpassthrough IO then S800 and S900, so if you need secondary HART values (is this what You mean by full HART support?) choose S900 and if You need only other functionalities (diagnostics, remote config etc.) You can use S800.
Best Regards,
Mike

This has been in many customers wish list for long time to have S800 support HART directly into controller.
Contact local ABB support and let them have an answer from Product Management.

and where is the question here? Obviously you already know that the S800 currently doesn't have this possibility but other IO's like S900 do, so it's possible with AC800M / 800xA....
