Communication via RS485
5.5 Communication via BACnet MS/TP - only CU230P-2 HVAC / BT
The inverter can simultaneously process up to 32 SubscribeCOV services. These can all
refer to the same object instances - or different object instances.
SubscribeCOV monitors the property changes of the following objects:
● Analog Input (AIxx),
● Analog Output (AOxx),
● Analog Value (AVxx),
● Binary Value (BVxx) and
● Multi-state Input (MSIxx)
Note
SubscribeCOV services are not retentive; i.e., when restarting the CU the master must
reinitiate SubscribeCOV services.
