Notice: For p0014 = 1, the following applies:
After the value has been modified, no further parameter modifications can be made and the status is shown in
r3996. Modifications can be made again when r3996 = 0.
Note: Field bus interface.
Changes only become effective after POWER ON.
The parameter is not influenced by setting the factory setting.
When p2030 = 1 (USS), the following applies:
Min./max./factory setting: 4/13/8
When p2030 = 2 (MODBUS), the following applies:
Min./max./factory setting: 5/7/7
If p2030 = 5 (BACnet), the following applies:
