9.1.2.2 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.

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)
Manual
Version 1.0.0
Value
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.

Explanation
Diagnostics reported by the I/O module do not
lead to the signaling of a diagnosis by the
fieldbus coupler.
Diagnostics reported by the I/O module lead to
the signaling of a diagnosis by the fieldbus
coupler.
switching of substitute values is enabled within
fieldbus coupler's parameterization, this value
is transmitted to the periphery in the event of a
fault.
