The SI-B3 option connects a 1000-series drive to a Building Automation and Control network
(BACnet) network and facilitates the exchange of data.
Users can monitor and control drives on a BACnet network using RS-485 technology and
MS/TP (Master-Slave/Token-Passing) protocol. The drives conform to the BACnet
application-specific controller (B-ASC) device profile.
Up to 127 drives can communicate on a single BACnet MS/TP network. Applications
requiring more drives or BACnet devices require a BACnet router to allow another MS/TP
network to be available with up to another 127 drives.
