BACnet_Param

Global settings and parameters for the library instance in the project can be defined and changed in this part of the library. Variables declared as CONSTANT are called parameters in TwinCAT and can be changed and adapted according to the requirements of the specific project.

Please note that the default parameters from the library repository remain unchanged. To restore the default values, simply remove the BACnet Rev14 library and add it back to the project.

BACnet_Param 1:

The default values provided by the library can be changed using the Value (Editable) column.

Example: Extending the text length of state text properties.

The following figure shows a default text length of 40 characters for text information provided in multistate and binary objects.

BACnet_Param 2:

For larger text information, the value can be changed from 40 to 60 characters by editing the value.

Important: These parameters (like other variable initializations in TwinCAT) are only applied after activating the project or after a reset origin and restart of the PLC.
