Names SHOWALARMAUTO
Effect The alarm is displayed whenever bit 0 of machine data ENABLE_ALARM_MASK is set.
The reaction should be set whenever an alarm should only occur during automatic
mode without manual operation by the user.
− Alarm reaction in automatic mode
Names SHOWWARNING
Effect The alarm is displayed whenever bit 1 of machine data ENABLE_ALARM_MASK is set.
It is designed for warnings which should normally be suppressed.
− Alarm view
Names ALLBAGS_NOREADY
Effect The Ready is canceled in all mode groups. The reaction thus corresponds to an NCK-
REACTIONVIEW|NOREADY, the difference being that the NC READY relay is not can-
celed and the corresponding VDI bit is not set. This is desirable in the event of an
emergency stop for example.
− Mode group not ready
Names DELAY_ALARM_REACTION
Effect If this alarm reaction is configured in the alarm handler, all alarm reactions for alarms,
which occur at this point, are buffered channel-specifically and are, therefore, not active.
The alarms are displayed on the MMC. Mode group and NC-wide reactions are trans-
ferred. The reaction is cleared by activating the clearDelayReaction call or by an alarm,
which has configured NO_DELAY_ALARM_REACTION. This activates all the delayed
alarm reactions.
− All channel-specific alarm reactions delayed on alarm, alarm display
Names NO_DELAY_ALARM_REACTION
Effect The DELAY_ALARM_REACTION state is canceled.
− The alarm reaction delay is canceled.
Names ONE_IPO_CLOCK_DELAY_ALARM_REACTION
Effect All alarm reactions are delayed by one cycle when an alarm is output. This functionality
became necessary as part of ESR development.
− All alarm reactions are delayed by one IPO cycle on alarm.
