How many of the most recent alarms does the FANUC alarm history store?

Explanation:
The alarm history on FANUC controllers is a rolling log that keeps track of the most recent alarms so you can review what happened leading up to a fault. It stores up to 100 alarms. When a new alarm appears and the log already has 100 entries, the oldest alarm is dropped to make room for the newest. This setup ensures you always have visibility into the most recent events, which is why the limit is 100 rather than smaller numbers like 25, 50, or 75.
