10.1.2.3 PROFINET IO Fieldbus Coupler 750-370
The aforementioned fieldbus coupler allows module-specific parameterization of
diagnosis and the substitute value behavior of the outputs as well as channel-
specific parameterization of the process data representation and the output
substitute value.

Explanation
Channel diagnosis
An external fault on the I/O module, in this case an undervoltage of the
field side power supply,
0 (false)
*)
does neither cause a transmission of a
diagnostic alarm nor an entry in the diagnostics
database of the station proxy.
1 (true)
entails transmission of a diagnostic alarm. This
external fault leads to an entry in the diagnostics
database of the station proxy.
Substitute value
behavior of outputs
If an established connection (AR), to which the submodule is assigned, is
disconnected or if the status of the “Provider State Flag” changes from
“RUN” to “STOP” in the APDU status of the consumer telegram,
according to device
settings
*)
the parameterized substitute value behavior of
the station proxy is applied. The parameterized
substitute value of the respective output channel
has no meaning in this context.
Outputs are set to 0
the data of all output channels is set to 0.
Outputs are set to last
valid values.
the last valid status of the respective output
channel is maintained. The parameterized
substitute value of the respective output channel
has no meaning in this context.
Outputs are set to
substitute values
the parameterized substitute value of the
respective output channel is output.
Process data
representation
Process data is represented
according to device
settings
*)
according to setting of station proxy (DAP)
INTEL (LSB-MSB)
in „Little Endian“ format
MOTOROLA (MSB-
LSB)
in „Big Endian“ format“
Output substitute
value
1)
Channel x (x = 0…7)
-
32767 … 0
*)
… 32767
In the state of missing output data, the set
substitute value is output on the respective
output channel if the substitute value behavior is
set to “Outputs are set to substitute values”.
*)
Default setting
1)
A substitute value less than 0 can only be selected using firmware versions as from
FW08 for 750-370
