Rockwell Automation 22-COMM-B PowerFlex BACnet MS/TP Adapter - Manual (Page 63)

Glossary
A
Adapter
Devices such as drives, controllers, and computers usually require an
adapter to provide a communication interface between them and a
network such as BACnet MS/TP. An adapter reads data on the network
and transmits it to the connected device. It also reads data in the device
and transmits it to the network.
The 22-COMM-B adapter connects PowerFlex 4, PowerFlex 4M,
PowerFlex 40 or PowerFlex 400 drives to a BACnet MS/TP network.
(NOTE: The 22-COMM-B adapter must have firmware version 1.003 or
later to be compatible with PowerFlex 4M drives.) Adapters are
sometimes also called “cards,” “embedded communication options,”
“gateways,” “modules,” and “peripherals.”
B
BACnet MS/TP
BACnet is a data communication protocol for Building Automation and
Control networks. BACnet MS/TP (master-slave/token-passing) is a
specific type of BACnet network designed to run at speeds of 1 Mbps or
less over twisted pair wiring.
Baud Rate
The speed at which data is transferred on the network. Each device on a
network must be set for the same baud rate.
C
ControlFLASH
An Allen-Bradley software tool that lets users electronically update
firmware on printed circuit boards.
D DSI (Drive Serial Interface)
DSI is based on the Modbus RTU serial communication protocol and is
used by various Allen-Bradley drives and power products, such as
PowerFlex 4-Class drives.
DSI Peripheral
A device that provides an interface between DSI and a network or user.
Peripheral devices are also referred to as “adapters” or “modules.” The
22-COMM-B adapter, 1203-USB or 22-SCM-232 converter, and
PowerFlex 4-Class HIMs (22-HIM-A3 or 22-HIM-C2S) are examples of
DSI peripherals.
