2.2 List of parameters
Note: Fieldbus IF: Fieldbus interface
Changes only become effective after POWER ON.
The parameter is not influenced by setting the factory setting.
The parameter is set to the factory setting when the protocol is reselected.
When p2030 = 1 (USS), the following applies:
Min./max./factory setting: 4/13/8
For p2030 = 2 (Modbus RTU), the following applies:
Min./max./factory setting: 5/13/7
For p2030 = 5 (BACnet MS/TP) the following applies:
Possible values/factory setting: (6, 7, 8, 10) / 8
If p2030 = 8 (P1), the following applies:
Min./max./factory setting: 5/7/5
Description: Displays or sets the address for the fieldbus interface (RS485).
The address can be set as follows:
1) Using the address switch on the Control Unit.
--> p2021 displays the address setting.
--> A change only becomes effective after a POWER ON.
2) Using p2021
--> Only if an address of 0 or an address that is invalid for the fieldbus selected in p2030 has been set using the
address switch.
--> The address is saved in a non-volatile fashion using the function "copy from RAM to ROM".
--> A change only becomes effective after a POWER ON.
Dependency: Refer to: p2030
Note: Changes only become effective after POWER ON.
The parameter is not influenced by setting the factory setting.
The parameter is set to the factory setting when the protocol is reselected.

When p2030 = 2 (Modbus), the following applies:
Min./max./factory setting: 1/247/1
If p2030 = 5 (BACnet), the following applies:
Min./max./factory setting: 0/127/1
If p2030 = 8 (P1), the following applies:
Min./max./factory setting: 1/99/99
