8.3 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)
