3 System Description
The 750 XTR Series is part of the WAGO I/O System 750.
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.
Figure 1: Fieldbus Node (Example)
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 a local 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.
