Comparator
Four values can be set in the Slave Unit, and compared with the Analog Data
values.
The four set values are the Alarm Trip Point High (HH), the Warning Trip Point
High (H), the Warning Trip Point Low (L), and the Alarm Trip Point Low (LL).
When the analog data value exceeds the set value, the Comparator Result
Flag in the area for Analog Status Flags turns ON. If an alarm does not occur,
the Normal Flag (pass signal) turns ON.
Note
When the analog input value changes earlier than the conversion cycle, the
High Limit alarm may turn ON without the Normal Flag (pass signal) turning
ON for the Low Limit alarm. Configure ladder programs to prevent this occur-
ring.
