Command: Force Function Block Input
Important
This kind of forcing uses a data breakpoint internally and is therefore different from forcing with the Force Values command or the F7 key. Values which have been forced with the Force Function Block Input command do not respond to the Watch All Forces or Unforce All Values commands.
Function: The command opens the Force Value dialog to force the selected input of a function block. Forcing can be canceled with the same command and dialog.
Call: CFC menu; context menu
Requirements:
The CFC editor is in online mode and the input of the function block is selected.
For compiler versions 3.5.11.x and 3.5.12.x, the "forceability" of the box is enabled by the Prepare Box for Forcing command.
In the Force Value dialog, you can either specify a value that the input of the function block should be forced, or remove the currently forced value.
After forcing, the input is highlighted in green again. Boolean inputs get a small monitoring view with the forced value. The forced value is displayed in the Value column of monitoring views (in the declaration part of the POU or in a watch list).
