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.
For standard modules, the parameter data set is sent to the data set number or
index 0x4000 or 16384.
This data set receives the following attributes.

Substitute value behavior

Description
Substitute value
behavior
according to device
settings
If an established 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 parameterized substitute value behavior of the
station proxy is applied for the duration of missing
output data. The parameterized substitute value of
the respective output channel has no meaning in
this context.
keep last valid value
If an established 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. The parameterized substitute value of the
respective output channel has no meaning in this
context.
set substitute value
If an established 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 parameterized substitute value of the respective
output channel is output for the duration of the
missing output data.

Attribute Value
Description
Substitute value
(1 Byte)
0 (false)
In the state of missing output data, status '0' is
output on the respective output channel with the set
substitute value behavior "Output substitute value".
1 (true)
In the state of missing output data, status '1' is
output on the respective output channel with the set
substitute value behavior "Output substitute value".
