Output processing
Output characteristics
Writing output
Overflow monitoring
The application must provide values in a standardized format to the output: 0 to
+10000.
The values must be written in the word %QW0.10.
If the value provided by the application is less than 0 or greater than 10000, the analog output saturates to 0 V or + 10 V.
An overflow bit usable by the program is then positioned to 1.
Bit Name
%I0.10.ERR
Meaning
Channel 10 fault (analog output)
Digital / analog conversion
Refreshing the output
Fallback value
Digital / analog conversion is carried out on 8 bits:
The value provided by the application program (0 to 10000) is automatically transformed into a digital value which can be used by the converter.
Output is refreshed at the end of the MAST task or the FAST task, depending on the selection made at configuration (See Modifying the task to which the output is
assigned, p. 250).
The output takes the fallback value: l l l l
If dialog with the PLC is no longer possible
If the PLC switches to STOP mode
These fallback values are selected at configuration (See Modification of the Fallback
Mode, p. 249)
Possible options are:
Value 0
Maintained at the last value sent
180
