The following product and fieldbus-specific terms and abbre-

viations are used in this description:

Term/abbreviation Significance

Bus nodes create the connection to certain fieldbuses/networks, pass on control

signals to the connected devices/modules and monitor their functioning.

CLEAR_DATA This command, sent by the master, resets all outputs of the addressed

slave.

DI, DO, DX Digital inputs (DI) or outputs (DO) or digital inputs and outputs (DX)

DIL switches Dual-In-Line switches usually comprise several switch elements that can

be used to make hardware settings.

DP PROFIBUS protocol for decentralised peripheral equipment, such as

sensors and actuators, and their cyclical communication functions (data

exchange and diagnostic messages) through DPV0-protocol or acyclic,

need-dependent data exchange and alarm handling through DPV1-pro-

tocol.

Hexadecimal numbers are marked by a low-set “h”.

Fail state This is a function which can automatically activate the “Hold last state” in

the event of connection errors (program abort or timeout of the fieldbus

connection) and is also designated “fail safe” in some cases.

FREEZE This command, sent by the master, freezes all inputs of the slave. The

slave now sends a constant image of all inputs, independent of their fur-

ther change in status. The input image is updated with each further trans-

mission of the FREEZE command.

A FREEZE command is cancelled with UNFREEZE.

GSD General Station Description (or Gerätestammdatei - device master file)

stands for the individual electronic data sheet of the device type. It is

made available by the device manufacturer.

Hold last state defines the status which outputs/valves are to assume after fieldbus

and/or communication errors

I&M stands for ‘Identification and Maintenance’ and represents the electronic

name plate of the bus node.

Load voltage includes the power supply for connected devices and (digital) outputs,

e.g. solenoid coils of valves

Term/abbreviation Significance

Master The master/DP master is an active device that determines the data traffic

in the fieldbus system PROFIBUS-DP and may send messages/commands

without external request if there is a transmission authorisation.

The DP master can be an individual device or part of a programmable logic

controller (PLC).

O, I Digital output, digital input

OB Output byte

Operating voltage also designated signal voltage : includes the power supply for electronics

and sensors

PLC Programmable Logic Controller (German: Speicherprogrammierbare

Steuerung (SPS))

Power supply Heading term for operating and load voltage supplies

PROFIBUS DP is the PROFIBUS variant for speed-optimised, serial data exchange with

decentralised stations and is performed cyclically with the protocol DPV0.

Slave The slave/DP slave is a passive peripheral device that receives messages/

commands of the master, implements and acknowledges them or re-

sponds with a message on request of a master.

Station address Address of the fieldbus station, also designated PROFIBUS address or

station number

Status bits Internal inputs, which supply coded common diagnostic messages

PLC/IPC programmable logic controller/industrial PC, also designated system

controller or controller (German: SPS)

SYNC A SYNC command causes all slaves addressed by the master to freeze

their own output data and buffer the data transferred from the master,

which will be switched through to the physical outputs at the next SYNC

command.

A SYNC command is cancelled with UNSYNC.
