14.2.2 Digital Output Modules (DO)
All digital output modules receive a parameter data set from the IO controller in
the form of a record write request.
The parameter data set is sent to the data set number or index 0x4000 or 16384.
This data set receives the following attributes.

Attributes for the Digital Output Modules (DO)
-
Substitute value behavior of the outputs
-
Substitute output status

Description
Substitute value
behavior of the outputs
If an established connection (AR) is disconnected
to which the submodule is assigned or when the
status of the “Provider State Flag” changes in the
APDU status of the consumer telegram from
“RUN” to “STOP”, the last valid status of the
respective output channel is retained for the
duration of the missing output data.
according to the
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 status of all output channels is set to 0.
Outputs maintain the
last valid value.
•
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 take their
substitute states.
•
the parameterized substitute value of the
respective output channel is output.

Attribute value
Description
Substitute output status
If output data is missing with the “Substitute
value” behavior set:
0 (false)
•
the ‘0’ status is output at the respective output
channel.
1 (true)
•
the ‘1’ status is output at the respective output
channel.
