System Description
The WAGO-I/O-SYSTEM 750 is a modular, fieldbus-independent input/output
system (I/O system). The configuration described here consists of a fieldbus
coupler/controller (1) and the modular I/O modules (2) for any signal shapes that
form the fieldbus node together. The end module (3) completes the node and is
required for correct operation of the fieldbus node.

Fieldbus couplers/controllers are available for different fieldbus systems.
The standard fieldbus couplers/controllers contain 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 I/O
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/controller exchanges process data with the respective control
via the respective fieldbus. The programmable fieldbus controllers (PFC) allow
implementation of additional PLC functions. WAGO-I/O-
PRO
is used to program
the fieldbus controllers according to IEC 61131-3.
I/O modules for diverse digital and analog I/O signals as well as special functions
can be connected to the fieldbus coupler/controller. The communication between
the fieldbus coupler/controller and the I/O modules is carried out via an internal
bus.
The components of the WAGO-I/O-SYSTEM 750 have clear termination points,
light emitting diodes for status display, plug-in mini WSB tags and group marker
cards for labeling.
The 1, 2 or 3 wire technology supplemented by a ground wire connection allows
for direct sensor or actuator wiring.
