Significance
The synchronized action is only effective in the automatic mode.
It applies only to the next executable block (block with motion
statement or other machine action), is non-modal.
Example:
WHEN $A_IN[3]==TRUE DO $A_OUTA[4]=10
The synchronized action applies modally in the following blocks and
can be deactivated by CANCEL(<n>) or can be overwritten by
programming a new synchronized action with the same ID.
The synchronized actions active in the M30 block delay the program
end.
ID synchronized actions are only effective in the automatic mode.
Value range for <n>:
Example:
ID=2 EVERY $A_IN[1]==1 DO POS[X]=0
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. This means that it is
possible to activate actions that should run in the NC independent of
the selected operating mode.
Value range for <n>:
Example:
IDS=1 EVERY $A_IN[1]==1 DO POS[X]=100
