Summary

If an Alarm (communicated as Alarm_8P) occours during communication loss to the PLC  this alarm is not shown in the runtime if the communication continues again. Neither the PLC is reconnected after few minutes. This means the alarm is completely lost in zenon.
 Only you restart the runtime, the alarm is shown.
