Rockwell Automation 20-COMM-I Interbus Adapter - Manual (Page 106)

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 Interbus. 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 20-COMM-I Interbus adapter is an adapter that connects,
PowerFlex drives to a Interbus network. Adapters are sometimes also
called “embedded communication options,” “modules,” and
“peripherals.”
C CMD Software
IBS CMD G4 is a software package that enables Configuration,
Monitoring, and Diagnostics of all connected devices in an Interbus
network.
Communication Reference (CR)
The communication reference identifies an Interbus device in the
parameter data channel (PCP). To send a PCP service to a device, its CR
must be specified. The CRs begin at “2” and must be assigned in
ascending order.
ControlFLASH
ControlFLASH is an Allen-Bradley software tool that lets users
electronically update firmware on printed circuit boards. The tool takes
advantage of the growing use of flash memory (electronic erasable
chips) across industrial control products.
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 data rate is the speed at which data is transferred on the Interbus
network (fixed at 500k/bps).
