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 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 rele-
vant 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 program-
mable 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 be-
tween 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 in-
dication, insertable mini WSB markers and pullout group marker carriers. The
3-wire technology supplemented by a ground wire connection allows for di-
rect sensor/actuator wiring.
