Issue
How many MSTP networks can you connect to an Automation Server (AS or AS-B)?
Product Line
EcoStruxure Building Operation
Environment
- Version 1.3 and newer
- MSTP Network on an StruxureWare Building Operation Automation Server (AS or AS-B)
- BACnet MSTP Devices
Cause
Require 2 separate MSTP networks, either to use 2 different Baud rates or to speed up the network and split the devices across the 2 ports.
Resolution
You can create 2 separate MSTP networks under the BACnet interface of an AS-B or AS (version 1.3 or higher), one on Comm A the other Comm B.
Each can run at different Baud rates if required.
For the number of supported devices please reference, Maximum number using StruxureWare Building Operation (Scalability and Capacity). Please be aware that the listed maximum is for the Automation Server allowing you to distribute between the two comm ports.
