Parameters: %1 = Channel ID %2 = Action number/action name Definitions: The setting of the MD20108 $MC_PROG_EVENT_MASK fo rces an asynchronous subprogram to be triggered automatically on RESET or PowerOn. T he implicitly triggered asynchronous subprograms are normally called "Event-triggered program call" or "Program event". In the alarm situation, this asynchronous subprogram could not yet be activated; that is why the action (normally start of part program) must be rejected. Reasons for the fact that the asynchronous subprogram could not be triggered: 1. The asynchronous subprogram does not exist (/_N_CMA_DIR/_N_PROG_EVENT_SPF) 2. The asynchronous subprogram is allowed to start in the referenced state only (see MD11602 $MN_ASUP_START_MASK) 3. READY is missing (because of alarm) Reaction: Alarm display. Remedy: Load program Check MD11602 $MN_ASUP_START_MASK Acknowledge alarm Program Continuation: Clear alarm with the Delete key or NC START.
