Communication via RS485
5.5 Communication via BACnet MS/TP - only CU230P-2 HVAC / BT
Device name - default setting, change name, restore factory setting
In BACnet, the Control Unit has a unique name, which is required for identification when
replacing a device etc.
The device name is preset at initial power up. It has the following structure:
The name is represented in the ASCII format in the 79 indices of p7610.
Changing device names - procedure
1. To change, overwrite p7610 either directly in the inverter or write the name via the control
using the "Object Write Property Object Device, Object Name".
2. If you are working with Startdrive, back up the settings so they are not lost if the power
fails.
3. Switch off the inverter power supply to activate the name.
4. Wait until all LEDs on the inverter are dark.
5. Switch on the inverter power supply again.
Your settings become effective after switching on.
You have now changed the name.
❒
When restoring the factory setting, the device name is not changed.
If you wish to reset the name to the original value, set p7610[0] = 0 and activate it as
described above.
Interconnecting analog outputs
If you set communication via BACnet (p2030 = 5) then the analog outputs of the inverter are
internally interconnected with the fieldbus analog outputs:
● p0771[0] = 791[0]
● p0771[1] = 791[1].
The values for p0791[0] and p0791[1] are written via objects ANALOG OUTPUT 0 and
ANALOG OUTPUT 1. Interconnections between parameter p0791 and other sources are
rejected.
This means that the control outputs system-specific values via the analog outputs of the
inverter.
However, if you still wish to display an inverter-specific value, then you must adapt the
appropriate wiring.
