Control behavior in specific operating states

10.7
POWER ON
No synchronized actions are ever active during POWER ON. Static synchronized actions
can be activated by an asynchronized subprogram (ASUB) started by the PLC.
Mode change
Synchronized actions activated by keyword IDS remain active after a change in operating
mode. All other synchronized actions become inactive on a change in operating mode (e.g.
axis positioning) and are reactivated following repositioning and a return to automatic mode.
RESET
An NC reset terminates all non-modal and modal synchronized actions. Static synchronized
actions remain active. They can start new actions. If a command axis movement is active on
RESET, this is canceled. Previously executed synchronized actions of the WHEN type are
not processed again after RESET.
