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 B

uilding 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.
