10.1.2.2 PROFIBUS DP Fieldbus Coupler
750-333(/0xx-000), 750-833(/0xx-000)
The aforementioned fieldbus couplers or controllers allow module-specific
parameterization of diagnosis behavior as well as channel-specific
parameterization of a substitute value.

Explanation
Diagnosis
The fieldbus coupler signals a diagnosis if an undervoltage of I/O module’s
field side power supply arises. This kind of module diagnosis is referred to
channel 0.
0 (disabled)
*)
Diagnostics reported by the I/O module do not
lead to the signaling of a diagnosis by the
fieldbus coupler.
1 (enabled)
Diagnostics reported by the I/O module lead to
the signaling of a diagnosis by the fieldbus
coupler.
Substitute value
1)
Channel x (x = 0…7)
-
32767 … 0
*)
… 32767
If, in the event of a PROFIBUS DP fault, the
switching of substitute values is enabled within
fieldbus coupler’s parameterization, this value is
transmitted to the periphery in the event of a
fault.
*)
Default setting
1)
A substitute value unequal 0 can only be selected using firmware versions as from
FW17 for 750-833(/0xx-000) or FW18 for 750-333(/0xx-000)
