4.1 Checklist for designing BACnet/IP networks
Small to mid-sized project
Consider the following questions for detailed planning when designing a small to mid-sized project with a
low level of network complexity:
Question Designing the BACnet network Designing the IP network
Is the number of Desigo room automation
stations < 500?
One BACnet network Small to mid-size project and networks
of a lower complexity
Does the number of primary plants,
implemented with Desigo PXC, < 200?
One BACnet network
Are only HVAC and Desigo room automation
planned on this project?
Is only one building or building section
automated on this project?
Are BACnet third-party devices used? Own BACnet network
Does data exchange need to be implemented
between BACnet third-party devices and Desigo
units (PXC)?
Same UDP port
Do you anticipate commanding more than 500
group member on central functions (emergency,
service, or protection functions or operating
modes and set points for lighting, blinds, HVAC,
fire and wind, etc.)?
No → OK
The central functions need to be divided
up for more than 500 group members.
A group member is not the same as a
room segment. A room segment can
include lots of group members.
Do you anticipate more than 250 group
members on central functions that supply
demand signals to supply systems?
A cooling or heating valve sends out a demand
signal. A room segment can send out multiple
demand signals.
No → OK
The central functions need to be divided
up for more than 250 group members.
A group member is not the same as a
room segment. A room segment can
include lots of group members.
Superposed, it is used to monitor devices and
schedule a monitoring device. Is there more
than 500 BACnet references or more than 50
scheduler programs with a maximum of 5
references?
No → OK
