Safety Notes
WAGO-I/O-SYSTEM 750
ETHERNET StarterKit 1
1.4 Safety Notes
Attention
Switch off the system prior to working on bus modules!
In the event of deformed contacts, the module in question is to be replaced, as
its functionality can no longer be ensured on a long-term basis.
The components are not resistant against materials having seeping and
insulating properties. Belonging to this group of materials is: e.g. aerosols,
silicones, triglycerides (found in some hand creams).
If it cannot be ruled out that these materials appear in the component
environment, then additional measures are to be taken:
- installation of the components into an appropriate enclosure
- handling of the components only with clean tools and materials.
Attention
Cleaning of soiled contacts may only be done with ethyl alcohol and leather
cloths. Thereby, the ESD information is to be regarded.
Do not use any contact spray. The spray may impair the functioning of the
contact area.
The WAGO-I/O-SYSTEM 750 and its components are an open system. It
must only be assembled in housings, cabinets or in electrical operation rooms.
Access must only be given via a key or tool to authorized qualified personnel.
The relevant valid and applicable standards and guidelines concerning the
installation of switch boxes are to be observed.
ESD (Electrostatic Discharge)
The modules are equipped with electronic components that may be destroyed
by electrostatic discharge. When handling the modules, ensure that the
environment (persons, workplace and packing) is well grounded. Avoid
touching conductive components, e.g. gold contacts.
1.5 Scope
These quick start instructions describe the ETHERNET StarterKit 1
with the Ethernet fieldbus controller 750-842 and the basic components 750-
430, -530, -600, 787-602 and 759-312 of the WAGO-I/O-SYSTEM.
You will find detailed information about operation, assembly and start-up in
the manuals “Ethernet TCP/IP 750-342, 750-842“ and “WAGO- I/O-PRO 32“.
This documentation is hence only valid in connection with the appropriate
manuals.

Further information
You can also find the manuals “Ethernet TCP/IP 750-342, 750-842“ and
„WAGO-I/O-PRO 32“ on our “ELECTRONICC Tools & Docs“ (Item no.:
0888-0412/0001-0101) and on the Internet under: www.wago.com
2 Quick Start
2.1 Node assembly
Build up the fieldbus node as follows (from left to right):
750-842; 750-430 ; 750-530 ; 750-600.
Connect the supplies for the controller and for the power jumper contacts to
the DC 24 V power supply unit 787-602 (see Fig.1).
In this example it would be sufficient to bridge “24V“ and “+“
or “0V“ and “-“.

Ethernet network start-up
WAGO-I/O-SYSTEM 750
ETHERNET StarterKit 1
2.2 Ethernet network start-up
Connect the fieldbus node to your Ethernet network.
Either connect it directly to a PC using a crossover cable (crossed Ethernet
cables) or to a Hub or a Switch using a 1-to-1 patch cable.
Please write down the following Ethernet settings of your PC: the IP address
(e.g. 192.168.1.1), the Subnet Mask (e.g. 255.255.0.0) and possibly the
Gateway IP address.
You can see the settings under Start !Settings !Network and Dialup
Connections.
Your network administrator can give you more information
Write down the MAC ID of the controller 750-842 which you can find on the
barcode sticker or on the circuit diagram on the back of the controller.
Install the ”WAGO BootP Server“ which you can find on the
“ELECTRONICC Tools and Docs“ CD (Item no.: 0888-0412/0001-0101) or
on the Internet under: www.wago.com !Service !Downloads !Software.
Click the “Edit Bootptab“ button. Create an entry in the bootptab file with the
following structure:
”Any name“ : ht=1 : ha= „MAC Id of the coupler“ : ip= „New IP address of
the coupler“ : sm= „Subnet mask“
Example:
Wago:ht=1:ha=0030DE001234:ip=192.168.1.2:sm=255.255.0.0:
Restart the BootP Server via the ”Start“ button and disconnect the fieldbus
node from the power supply for approx. 2 s.
The Controller 750-842 will now send a BootP Request and will receive the IP
address from the BootP Server.
The IP address is now stored permanently.
Note
The permanent storage of the IP address for the ETHERNET fieldbus
controller 750-842 is achieved in a different way as it is the case with the
ETHERNET fieldbus controller 750-841.
Leave the controller turned on and turn off the BootP Server.
Start a browser (e.g. Internet Explorer, Netscape Navigator).
Enter the IP address of the controller 750-842 into the address bar of your
browser (e.g. http://192.168.1.2).

2.3 The first program
Prerequisite:
The WAGO-I/O-PRO 32 software has to be installed correctly and started.
You can start a new project via !File !New.
Example:
Fig. 3: WAGO-I/O-PRO 32, Creating a new POU
A new POU “PLC_PRG“ is created using the programming language “ST“
(Fig. 3) .
Before programming the controller 750-842, it must be selected. This is done
via !Extras !PLC selection.
Fig. 4: WAGO-I/O-PRO 32, Coupler selection
Choose ”750-842 Vx.x Ethernet Controller“ (Fig. 4).
A PLC configuration under !Resources !PLC Configuration is not made
with the Ethernet controller 750-842.
