Which BACnet data link layers does CBMS Studio Support?
It supports BACnet/IP, BACnet MSTP and BACnet Virtual Networks. BACnet MSTP requires an RS485 connection and there are 2 of these on the AAC-1000 controller. An RS485 add on board can be purchased for the Raspberry PI, while an RS485 USB interface can be purchased for Windows and Linux PC’s.
Which RS485 add on board should I use for a Raspberry PI?
We recommend using the raspicomm from Amescon if you wish to make your Raspberry PI support BACnet MSTP.
Can CBMS Studio operate as a BACnet/IP to BACnet/MSTP router?
Yes, if there are 1 or BACnet Ports enabled, then it will act as a BACnet router. For example if there is 1 BACnet/IP port and 1 BACnet MSTP port it will operate as a BACnet/IP to BACnet/MSTP router.
Can CBMS Studio operate a router between 2 BACnet/IP ports?
Yes, when you add 2 BACnet/IP port CBMS Studio will act as a router between the two. The port numbers need to be different, for example 47808 and 47809.
Does CBMS Studio operate as a BACnet device?
Yes, it operates as a BACnet device with BACnet objects that can be accessed from and device on the network.
Can I add a BACnet Schedule Object?
Yes, you can add a BACnet Schedule to CBMS Studio and use this in the Sedona Wiresheet.
Can I add a BACnet Alarm?
Yes, alarms can be configured with the Event Enrolment Object. When an alarm becomes active then it can be sent to a BACnet Workstation using the Notification Class object.
What is a BACnet Virtual Network?
A virtual network is not a physical network like BACnet/IP or BACnet/MSTP, it is a network that exists within the router and simulates a physical network. It has its own BACnet network number and it contains 1 or more BACnet devices. The Virtual Network makes it possible for CBMS Studio to act as multiple BACnet Devices.
