to S800 I/O via the TU812 termination unit which provides a D-sub connector. For

Support for HART Communication
S800 I/O provides possibilities to communicate via HART protocol with HART
Field Devices via PROFIBUS-DPV1 using CI840 or CI801 or AF100 using CI810
or CI820. There are four I/O modules that have HART interface, AI815, AI845,
AO815, AO845, AO845A, AI895 and AO895.
For HART connection via external HART MUX, see Support for connections to
instruments in Hazardous Areas on page 55.
S800 I/O provides the possibilities for HART communication, but the user
function is defined by the system (operator stations and controllers) S800 I/O is
included in. Always read the relevant system documentation for information
about the supported features and needed components of S800 I/O.
On PROFIBUS, an Extended HART mode gives a possibility to pass-through
long HART data frames up to 227 bytes. This will reduce the possible amount of
I/O modules per station. The longest HART data frame without the Extended
HART mode is 64 bytes.
