Configuring exported objects for write
The station may need to write to a property like Out Of Service or Notify Type. If an exported NumericWritable has an alarm extension, and you want to permit external BACnet writes to its alarm limit
values. In both cases you need to configure the BACnet user to have admin write permissions on the exported Boolean Writable and NumericWritable points.
The BACnet user is initially created without any permissions. This procedure documents how to assign the necessary permissions to the BACnet user.
- Expand and double-click a writable point that the system will export.The point’s Property Sheet opens.
- To allow an invoked Active action from BACnet to an exported BooleanWritable, make the point
BACnet Writableat priority. - Next, expand the and double-click the BACnet user.The BACnet (User) property sheet opens.
- Configure the station’s BACnet user to have operator write permissions by right-click the chevron to the right of the
Permissionsproperty.The Permissions grid opens. - With the Admin category selected, click the cell under Operator, W.This configures the BACnet user with operator write permission.
BACnet user permissions also apply to writes of any exported files and histories. While a password for the BACnet user is technically not needed (for external BACnet access), you should assign one anyway, because of the write permissions typically assigned.
- Configure a password for the BACnet user.Make it a non-blank password, and guard this password carefully!
- To complete the configuration, click OK.
