Telecontrol Quick-Start Manual
1.4 Safety Information
NOTICE
Switch off the power before replacing any components!
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 are: 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 in an appropriate enclosure.
- Handling of the components only with clean tools and materials.
NOTE
Soiled contacts may only be cleaned with ethyl alcohol and a leather cloth. In
doing so, attention must be paid to the ESD information.
Do not use contact sprays, which in extreme cases could impair the operation
of the contact.
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 regarding the
installation of switch cabinets must 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 items
in the environment (personnel, workplace and packaging) are well grounded.
Do not touch conducting parts; e.g., gold data contacts.
1.5 Scope of Validity
This quick-start manual describes the programming of the 750-872 controller
as the master of an outstation as defined by IEC 60870-5-101 and -104 with
some basic modules from the WAGO-I/O-SYSTEM for telecontrol.
Detailed information relating to handling, assembly and start-up is described
in the "Ethernet TCP/IP 750-872" and "WAGO-I/O-PRO CAA" manuals. This
documentation is therefore only valid in conjunction with the appropriate
manuals.

2.1 Hardware Design
Build up the node as follows (from left to right):
750-872; 750-400; 750-501; 750-461; 750-600.
Connect the 24V DC power unit to the supply (24V and 0V) for the controller
and for the power contacts (see Fig. 1).
For the application used in the example, it is sufficient to connect a jumper
between "24V" and "+" and between "0V" and "-".

2.2 Ethernet Network Start-Up
The IP address is conveniently assigned using the serial programming cable
provided and the "WAGO Ethernet Settings" program. Connect your PC to the
node's configuration and programming interface. Install the "WAGO Ethernet
Settings" program. You will find it on the "Tools & Docs" CD as well as on
the WAGO website under Service Downloads Software. After starting, the
program will determine the current node settings.

If the connection should time out, you can force the display to update with
"Identify". If the problem should persist, check the COM port setting and the
cabling.
