Glossary

Technical term

Meaning

Acknowledgement

Acknowledgement of a setting or change (e. g. of parameters))

Application

as directed:
Appropriate use of the machine according to the manufacturer’s information or to common use because of its design and function.

inappropriate
The use of the machine which does not comply with the manufacturer’s declaration.

Baud rate

Transmission speed of data in bit/s

Bus participant

Unit which communicates with the host via the bus

Bus terminal

Network node between long-distance and peripheral bus

Code

For input and display (access) of parameter values.

Code number

Clear labelling of a parameter, e.g. C0106.

Controller

General term for servo drives, frequency inverters and DC drives

Cycle time

The cycle time of the communication system is the time required for the exchange of all process data between the host and the field
units (e.g. controllers).

Data format

Data description, consisting of the components data structure and data type.

DRIVECOM

Group of more than 30 drive manufacturers. They have created uniform communication solutions for power transmission. A result is a
standardized drive profile „DRIVECOM profile drive technology 21“ (see Profile).

Fieldbus

For the exchange of data between higher-level controls (hosts) and positioning controls (e. g. controllers).

Host

PC or PLC

Icon

Sign or symbol with an unambiguous message.

Index

Parameter number according to the PROFIBUS and DRIVECOM definitions. If a parameter comprises several values (e.g. arrays and
records), they are addressed by an additional subindex.

InterBus

Serial bus system of Phoenix Contact

Lenze code number

see code number

Master

see host/host system

Network topology

Design and structure of a network: e.g. point-to-point network, line network, ring network)

Parameter

Adjustable controller variables and values addressable via codes

Peripheral-bus module

Bus participant in the peripheral bus

Peripheral-bus station

Consists of bus terminal, peripheral-bus module and long-distance bus controller.

Process data

Small amounts of data (e.g. 2 bytes, DRIVECOM) for fast and cyclic transmission; e.g. setpoints and actual values

Process-data channel

Communication channel for fast and cyclic transmission of process data

Profile

The word „profile“ originates from the communication standard DIN 19245 and describes supplementary and restrictive regulations,
which are valid for industry groups or device groups.
The DRIVECOM-Nutzergruppe e. V. has standardized some important unit functions and summarized the results in the „DRIVECOM profile
drive technology 21“.

Slave

Bus participant which is only allowed to transmit data after a request by a master. For instance, controllers are slaves. (See host/host
system)
