Bacnet Trend; Bacnet Client Configuration Limitations; Device And Points Limitation - Johnson Controls EasyIO FS Series User Manual

BACnet trend

The EasyIO FS series supports the BACnet trend. There are a total of 32 BACnet trends available. You can configure
the trends as Boolean trend, Analog trend, or Multistate trend. Each trend allows up to 1,000 records. The trend
performs a first in first out process, when the stopIsFull policy is set to false.
To clear the records, right-click the BACnetTrend object, click Actions, and click clearRecords. Use the manual
process to link a valid value to the BACnet Trend objects. The BACnet Trend objects do not trend any valid value by
themselves. You can trend a valid temp value as a BACnet object.
