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 Profibus. 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-P Profibus adapter connects PowerFlex 4-Class drives to
a Profibus Network. Adapters are sometimes also called “cards,”
“embedded communication options,” “gateways,” “modules,” and
“peripherals.”
C ControlFLASH
An Allen-Bradley software tool that lets users electronically update
firmware on printed circuit boards.
Controller
A controller, also called programmable logic controller, is a solid-state
control system that has a user-programmable memory for storage of
instructions to implement specific functions such as I/O control, logic,
timing, counting, report generation, communication, arithmetic, and data
file manipulation. A controller consists of a central processor, input/
output interface, and memory. See also Scanner.
D Data Rate
The speed at which data is transferred on the Profibus network. The
available data rates depend on the type of cable and total cable length
used on the network:
Baud Rate Maximum Cable Length
9.6 Kbps 1000 m
19.2 Kbps 1000 m
93.75 Kbps 1000 m
187.5 Kbps 1000 m
500 Kbps 400 m
1.5 Mbps 200 m
3 Mbps 100 m
6 Mbps 100 m
12 Mbps 100 m
