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 has the following structure in the factory setting:
The name is represented in the ASCII format in the 79 indices of p7610.
Procedure
To change the names, proceed as follows
1. To change, overwrite p7610 – either directly with Starter, BOP or IOP – or you write the
name via the control using the "Object Write Property Object Device, Object Name".
2. When you are working with STARTER, backup your settings with
3. Switch off the inverter power supply to activate the name.
4. Wait until all LEDs on the inverter go dark.
5. Switch on the inverter supply voltage again.
Your settings become active after switching on.
This means that you have 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.
