u About this Product
The SI-B3 option connects an A1000 drives to a BACnet network and facilitates the exchange
of data.
This manual explains the handling, installation and specifications of this product. The SI-B3
option is a simple, networking solution that reduces the cost and time to wire and install factory
automation devices, while providing interchangeability of like components from multiple
vendors.
Drives can be monitored and controlled by a controller on a Building Automation and Control
network (BACnet) 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. If more drives or
BACnet devices are required, then a BACnet router is required to allow another MS/TP
network to be available with up to another 127 drives.
