2.1.3 Use of the WAGO-I/O-SYSTEM 750 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 devices 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 devices in wet and dusty
environments is prohibited.
Operating the WAGO-I/O-SYSTEM 750 devices 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 “Device Description” > “Standards and Guidelines” in the manual
for the used fieldbus coupler/controller.

The components are not resistant to materials having seeping and insulating
properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for handling
devices/modules.

2.3 Special Use Conditions for ETHERNET Devices
If not otherwise specified, ETHERNET devices are intended for use on local
networks. Please note the following when using ETHERNET devices in your
system:
•Do not connect control components and control networks to an open
network such as the Internet or an office network. WAGO recommends
putting control components and control networks behind a firewall.
•Limit physical and electronic access to all automation components to
authorized personnel only.
•Change the default passwords before first use! This will reduce the risk of
unauthorized access to your system.
•Regularly change the passwords used! This will reduce the risk of
unauthorized access to your system.
•If remote access to control components and control networks is required,
use a Virtual Private Network (VPN).
•Regularly perform threat analyses. You can check whether the measures
taken meet your security requirements.
•Use “defense-in-depth” mechanisms in your system's security configuration
to restrict the access to and control of individual products and networks.

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 and 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 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.

3.2 Hardware Address (MAC ID)
Each ETHERNET Controller 10 MBit 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 the paper strip with two self-adhesive peel-
off strips 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.

3.3 Component Update
For the case of an update of one component, the lateral marking on each
component contains a prepared matrix.
This matrix makes columns available for altogether three updates to the entry of
the current update data, like production order number (NO; starting from calendar
week 13/2004), date stamp (DS), software version (SW), hardware version (HW)
and the firmware loader version (FWL, if available).

If the update of a component took place, the current version data are registered
into the columns of the matrix.
Additionally with the update of a fieldbus coupler or controller also the cover of
the configuration and programming interface of the fieldbus coupler or controller
is imprinted with the current production order number.
The original manufacturing information on the device's housing remains
unchanged.

3.4 Storage, Assembly and Transport
Whenever possible, the components are to be stored in their original packaging.
Likewise, the original packaging provides optimal protection during transport.
When assembling or repacking the components, the contacts must not be soiled or
damaged. The components must be stored and transported in appropriate
containers/packaging. Thereby, the ESD information is to be regarded.
