2.1.3 Use of the 750 Series in Compliance with Underlying
Provisions
Fieldbus couplers, fieldbus controllers and I/O modules found in the modular
WAGO-I/O-SYSTEM 750 receive digital and analog signals from sensors and
transmit them to actuators or higher-level control systems. Using programmable
controllers, the signals can also be (pre-) processed.
The components have been developed for use in an environment that meets the
IP20 protection class criteria. Protection against finger injury and solid impurities
up to 12.5 mm diameter is assured; protection against water damage is not
ensured. Unless otherwise specified, operation of the components in wet and
dusty environments is prohibited.
Operating 750 Series components in home applications without further measures
is only permitted if they meet the emission limits (emissions of interference)
according to EN 61000-6-3. You will find the relevant information in the section
on “WAGO-I/O-SYSTEM 750” “System Description” “Technical Data” in
the manual for the used fieldbus coupler/controller.

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 extended ECO fieldbus couplers 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 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/controller 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 in accordance
with 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 WAGO-I/O-SYSTEM 750 has a clear port level with LEDs for status
indication, insertable mini WSB markers and group marker carriers for marking.
The 1, 2 or 3 wire technology supplemented by a ground wire connection allows
for direct sensor or actuator wiring.

3.2 Hardware Address (MAC ID)
Each PROFINET IO advanced Fieldbus Coupler has an internationally
unambiguous physical address, referred to as the MAC-ID (Media Access Control
Identity).
As part of the labeling on the right side of this component, the MAC ID is printed
in the block diagram of the fieldbus coupler/controller.
In addition, the MAC ID is located on a self-adhesive tear-off label on the left side
of the fieldbus coupler/controller.
The MAC ID has a fixed length of 6 bytes (48 bits) which are presented
hexadecimal. The first three bytes identify the manufacturer (e.g. 00:30 DE for
WAGO). The second 3 bytes comprise the unique serial number of the hardware.
