2 The WAGO-I/O-SYSTEM 750

2.1 System Description

The WAGO-I/O-SYSTEM 750 is a modular, fieldbus independent I/O system.
It is comprised of a fieldbus coupler/controller (1) and up to 64 connected
fieldbus modules (2) for any type of signal. Together, these make up the
fieldbus node. The end module (3) completes the node.

Couplers / controllers for fieldbus systems such as PROFIBUS, INTERBUS,
ETHERNET TCP/IP, CAN (CANopen, DeviceNet, CAL), MODBUS, LON
and others are available.
The coupler / controller contains the fieldbus interface, electronics and a
power supply terminal. The fieldbus interface forms the physical interface to
the relevant fieldbus. The electronics process the data of the bus modules and
make it available for the fieldbus communication. The 24 V system supply and
the 24 V field supply are fed in via the integrated power supply terminal.
The fieldbus coupler communicates via the relevant fieldbus. The
programmable fieldbus controller (PFC) enables the implementation of
additional PLC functions. Programming is done with the WAGO-I/O-PRO 32
in accordance with IEC 61131-3.
Bus modules for diverse digital and analog I/O functions as well as special
functions can be connected to the coupler / controller. The communication
between the coupler/controller and the bus modules is carried out via an
internal bus.
The WAGO-I/O-SYSTEM 750 has a clear port level with LEDs for status
indication, insertable mini WSB markers and pullout group marker carriers.
The 3-wire technology supplemented by a ground wire connection allows for
direct sensor/actuator wiring.
