Fieldbus Dependent I/O Module
PROFIBUS DP
9 Glossary
Actuator Device driven by the I/O module.
Base Module Wiring level to connect the supply, the fieldbus con-
ductors and the sensors and actuators.
Electronic Module Plug-in component from the WAGO-I/O-SYSTEM
752
Fieldbus controller board
[Master]
Bus master which, as a higher ranking unit, controls
the data transmission on the bus. It interrogates the in-
put and status values of the slave devices and trans-
mits output and control data to them.
Processing unit for the interrogation of and access to
the decentral fieldbus equipment. It is the fieldbus
master which co-ordinates the bus traffic and transfers
the data to a control system.
Group [Input / output group, connection group]
General grouping of I/O channels. With their 8 chan-
nels, outputs form a supply group.
I/O addresses [I/O register]
Input / output area(s) for the I/O data
I/O data Input / Output data
I/O module Any fieldbus device from the WAGO-I/O-SYSTEM
752 series consisting of a base module and an elec-
tronic module for the recording and output of digital
signals.
I/O point Input / output point, signal input or output
Master Fieldbus controller board
Sensor [Generator, initiator]
Device interrogated by the I/O module.
Slave Bus slave addressed by a fieldbus master.
