2.1.1 Subject to Changes
WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any
alterations or modifications that serve to increase the efficiency of technical
progress. WAGO Kontakttechnik GmbH & Co. KG owns all rights arising from
the granting of patents or from the legal protection of utility patents. Third-party
products are always mentioned without any reference to patent rights. Thus, the

2.1.2 Personnel Qualifications
All sequences implemented on Series 750 devices may only be carried out by
electrical specialists with sufficient knowledge in automation. The specialists
must be familiar with the current norms and guidelines for the devices and
automated environments.
All changes to the coupler or controller should always be carried out by qualified
personnel with sufficient skills in PLC programming.

2.1.3 Use of the 750 Series in Compliance with Underlying
Provisions
Couplers, 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 the 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.
Appropriate housing (per 94/9/EG) is required when operating the WAGO-I/O-
SYSTEM 750 in hazardous environments. Please note that a prototype test
certificate must be obtained that confirms the correct installation of the system in
a housing or switch cabinet.

NOTICE
Protect the components against materials having seeping and insulating
properties!
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.

3.1 Hardware Design
The fieldbus node is to be installed as follows (viewed from left to right):
750-881; 750-400; 750-501; 750-600
The 24V DC power supply unit is linked to the 24V and 0V power for the fieldbus
controller and for the power jumper contacts (see No. 5 in the figure below).
For the application used in the example, it is sufficient to connect a jumper
between "24V" and "+" (see No. 6) or between "0V" and "-" (see No. 9).

3.2.2 Installing WAGO-I/O-PRO
The StarterKit "ETHERNET 881" includes a CD (Item No. 759-333) with the
development topology WAGO-I/O-PRO CAA.
WAGO-I/O-PRO CAA (CoDeSys) is a programming and visualization tool for
PLC programs. This software is used to develop PLC applications for WAGO-I/O
SYSTEM 750 programmable fieldbus controllers.
WAGO-I/O-PRO CAA runs in line with the IEC 61131-3 standard, which
specifies the requirements for a programming system.
You can use this programming tool to develop application programs in the
programming languages AWL, KOP, FUP, CFC, ST and AS.
Proceed as follows to perform the installation:
1. Place the WAGO-I/O-PRO CAA CD into your CD drive.
2. If the installation does not begin automatically, start the file Setup.exe.

3.2.3 Starting Up the Ehernet Network
This section provides you with a step-by-step sample procedure for starting up the
Ethernet network.
You must perform three steps to start up the network:
• Determine the IP address of your PC and change it if required
• Assign an IP address to the fieldbus controller
• Test the Ethernet link
The description of these work steps can be found in the corresponding following
sections.
Note
Good example!
This description is just an example and only describes the procedure for local
startup of a single fieldbus controller using a non-networked computer under the
Windows system.
3.2.3.1 Determining the IP address of your PC and changing it if required
The explanation below describes how you can determine the IP address currently
set for your PC and how you can change it if required.
1. To set up an Ethernet link connect the Ethernet port of your PC to one of the
two Ethernet ports of the fieldbus controller using the cross-over cable
provided with the system.
2. You can determine the IP address of your PC under:
Start > Settings > Networks > LAN.
Here, right click on the option PROPERTIES for the network you are
currently using (LAN X).
3. Then mark the item "Internet Protocol (TCP/IP)" in the popup list and
confirm by clicking [PROPERTIES].
