Glossary
The following terms and abbreviations are used throughout this manual. For
definitions of terms not listed here, see the Allen-Bradley Industrial Automation
Glossary, publication
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 25-COMM-P PROFIBUS DPV1 adapter connects PowerFlex 520-series
drives to a PROFIBUS DPV0/DPV1 network. Adapters are sometimes also
called ‘cards’, ‘embedded communication options’, ‘modules’, and ‘peripherals’.
Acyclic Messaging
PROFIBUS DPV1 acyclic messages are used to transfer data that does not
require continuous updates. Typically the read and write services used for acyclic
messaging are used to configure, monitor, and diagnose devices over the
PROFIBUS network.
Connected Components Work-
bench Software
The recommended tool for monitoring and configuring Allen-Bradley products
and network communication adapters. It can be used on computers running
various Microsoft Windows operating systems. You can obtain a free copy of
Connected Components Workbench software at
ControlFLASH
A free software tool used to electronically update the firmware of Allen-Bradley
products and network communication adapters. ControlFLASH software is
downloaded automatically when the firmware revision file for the product being
updated is downloaded from the Allen-Bradley updates website to your
computer.
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
