1.3.9 Determining BACnet Write Priority for Points
BACnet priorities are vary for different vendors. Siemens devices abide by the
following BACnet priority array:
● 1-6: Safety and protection
● 7: Delay time on/off
● 8: Manual operation
● 9-16: Program mode
If you want Building Operator to write to any value or output with a BACnet priority
array, you must determine a write level. Building Operator Discovery has its own
priority array, but it’s important to set the BACnet write level appropriately for the
end device.
Complete the following instructions to configure the write priority for BACnet points:
Changing Point Priority Individually
1. Find and select the appropriate value or output point beneath the device, in the
Available Equip tree.
2. In the point editor, find the Write Level field.
3. Use the up or down arrows, or type to enter 8 for the field value. Any command
you send to the Building Operator Discovery priority array will be sent out to the
end BACnet device at slot 8, or manual override.
