The static synchronized actions act modally in all modes. They even remain active
beyond the end of the program and can be activated directly after Power On using an
ASUB.
In this way, actions can be activated that are executed regardless of the mode selected in
the NC.
Example:
IDS=1 EVERY $A_IN[1]==1 DO POS[X]=100
10.1.3 Cyclic checking of the condition
Function
A keyword is used to define cyclic checking of the condition of a synchronized action.
If no keyword is programmed, the actions of the synchronized action is performed once in
every IPO cycle.
Keywords
No keyword Execution of the action is not subject to any
condition. The action is executed cyclically in any
interpolation cycles.
WHEN The condition is scanned in each interpolation cycle
until it is fulfilled once, whereupon the associated
action is executed once.
WHENEVER The condition is checked in cycles in each
interpolation cycle. The associated action is executed
in each interpolation cycle while the condition is
fulfilled.
FROM The condition is checked in each interpolation cycle
until it is fulfilled once. The action is then
executed while the synchronous action is active, i.e.
even if the condition is no longer fulfilled.
EVERY The condition is scanned in each interpolation cycle.
The action is executed once when the condition is
fulfilled.
Edge triggering:
the action is executed again when the condition
changes from the FALSE state to the TRUE state.
