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).

9.1.1
Setting Up using WAGO-I/O-
CHECK
It is only necessary to set the parameters of the HART I/O module using WAGO-
I/O-
CHECK
when the default operating mode (2AI + 6-byte mailbox) has been
changed to the “PROFIBUS operating mode” (2 AI + acyclic PROFIBUS
services) and is then to be changed back to the default mode. Changing to a
“PROFIBUS mode” or between PROFIBUS modes is typically carried out within
a PROFIBUS system using GSD in preference.
Restriction of Settings for PROFIBUS Operating Mode!
This changeover and operation with other than a PROFIBUS Coupler 750-333 or
Controller 750-833 is not yet possible at the present time for “PROFIBUS
operating modes” (2 AI + 1, 2, 3 or 4 HART variables per channel).
A HART I/O module that has once been set up for HART dynamic variables
using GSD files can therefore currently only be operated with a PROFIBUS
Coupler 750-333 or Controller 750-833.
It is then possible to restore the default state of the HART I/O module using
WAGO-I/O-
CHECK
and the PROFIBUS Coupler 750-333 or Controller
750-833. When doing so it must be ensured that the parameters of the
PROFIBUS Coupler 750-333 or Controller 750-833 are not set using GSD files.
Additional Information for the order of WAGO-I/O-
CHECK
You can order the WAGO-I/O-
CHECK
commissioning tool for the WAGO-I/O-
SYSTEM 750 from WAGO Kontakttechnik GmbH & Co. KG under the item
number 759-302.
