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/code
Clear labelling of a parameter, e.g. C0106. For the calculation rules see the Lenze code addressing in chapter “Parameter setting“,
page 6-1.
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. The data formats of the DRIVECOM parameters are
described in chapter 6.
Distributed peripherals (DP)
Input and output units which are serially connected with the central control.
DP master (class 1)
The DP master, which transfers user data by means of the assigned DP slave.
DP master (class 2)
The DP master, which is used as commissioning or diagnosis unit, usually a programming unit
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).
Handshake
Stipulated data-transfer method (here implemented by software).
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 with an additional subindex.
InterBus-S
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
PCP channel
By means of this communication channel, parameters can be transferred via PCP services following the PROFIBUS standard.
PCP service
“Commands“ with which it is possible to transfer parameters according to the PROFIBUS standard.
Peripheral-bus module
Bus participant in the peripheral bus
Peripheral-bus station
Consists of bus terminal, peripheral-bus module and long-distance bus controller.
PNO
PROFIBUS-Nutzerorganisation e.V. (PROFIBUS user organisation) Organisation for support and distribution of the PROFIBUS.
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
(PCD channel)
Communication channel for fast and cyclic transmission of process data
PROFIBUS
Communication standard DIN 19245 consisting of parts 1 to 3
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 20“.
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)
