Sequence of processing in a cycle: 1.Read inputs, 2. Force values 3. Process code, 4.
Force values, 5. Write outputs.
Note: Command "Force values [all applications]" which effects all applications of a
project, is not per default inserted in any menu. (if needed, please see the
Customization dialog)
Note: See in this context also the 'Write values' command for setting a defined value
only once at the beginning of a cycle.
The forcing will remain active until it is explicitly suspended by the user for particular
resp. for all variables, or until the application gets logged-out.
To prepare variables for forcing, the desired value must be defined in online mode in
one of the following places which are used for monitoring :
• In a watch view defined in the project, containing a list of variables to be
monitored (watch list).
• In the online view of the object within the declaration part of the respective editor.
• In the online view of the object within the implementation part of the FBD /LD/IL-
editor.
A forced value is indicated with a symbol.
