Operating Modes
The HART I/O module can be used with various operating modes depending on
connection and parameterization.

In the as-supplied state, the HART I/O module is configured in the default
operating mode as a 2-channel analog input module for 4 mA ... 20 mA signals
with HART functionality. In this default operating mode the I/O module can be
connected to all WAGO couplers and controllers listed in the table "Compatibility
List". In this case, HART communication is enabled by a 6-byte mailbox, which is
incorporated with the analog values in the cyclic process image.
In addition, five further operating modes can be set up specially for connecting to
the PROFIBUS DP/V1 Fieldbus Coupler 750-333 or Fieldbus Controller 750-833.
The section "Description of Operation" following the section on parameterization
and a short introduction to the FDT/DTM concept and HART via PROFIBUS,
describes the individual operating modes in the appropriate applications in more
detail together with a description of the communications process and brief
commissioning instructions in each case.

Setting the Operating Mode Parameters
Depending on the fieldbus used, the HART I/O module can either be
parameterized using the "759-302 WAGO-I/O-CHECK" commissioning tool for
WAGO-I/O-SYSTEM 750 or, for PROFIBUS, using the GSD files (device master
data) for PROFIBUS with installation program / Series 750, 752 and 755 (Item
No.: 750-910).
