Parameters for setting communication via BACnet

General settings
Processing times
p2024[0]: 0 ms ... 10000 ms, maximum processing time (APDU timeout), factory setting =
6000 ms,
p2024 [1 ... 2]: Irrelevant
BACnet communication parameter
● p2025 [0]: 0 ... 4194303: Device object instance number,
Factory setting = 1
● p2025 [1]: 1 ... 10:
● p2025 [2]: 0 ... 39:
factory setting = 3
● p2025 [3]: 1 ... 127: maximum master address, factory setting = 32
Setting the COV_Increments
(COV = change of values) 0 ... 4194303.000, factory setting = 1. A maximum of 32 COVs are
permissible.
COV_Increment: Changes the value of the "present value" of an object instance for which the
server transfers an UnConfirmedCOV_Notification or ConfirmedCOV_Notification.
You can use these parameters to set for which conerter value changes an
UnConfirmedCOV_Notification or ConfirmedCOV_Notification result is sent.
The factory setting 1 means that the converter sends an UnConfirmedCOV_Notification or
ConfirmedCOV_Notification if the considered value, e.g. for a range of 0 ... 10 V, changes by
an absolute value ≥ 1.
This requires an active SubscribeCOV_Service to send the relevant object instance.
You can also set the COV_Increment via the object property "COV_Increment" of the relevant
analog input, analog output or analog value.
BACnet language selection
German/English - only becomes effective after power off/on
Fieldbus error statistics
Displaying receive errors at the fieldbus interface
Device name - default setting, change name, restore factory setting
In BACnet, the Control Unit has a unique name, which is required for identification when
