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.
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.

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 The IO-Link Technology
IO-Link defines a communication standard (acc. IEC 61131-9) for connecting
both current digital inputs/outputs and intelligent IO-Link devices to the control
level. IO-Link devices describe sensors and actuators of the field level that have
IO-Link functionality.
The IO-Link technology is predominantly used in the industrial sector of
manufacturing automation. With IO-Link, configuration, diagnostics and
maintenance from the control are possible to the lowest field level in addition to
process data communication. For example, sensor failures can be diagnosed and
localize in the control directly.
With central parameter data storage in the IO-Link master and the possibility of
project development, attached devices can be simply replaced and configurations
copied.
Communication occurs via serial point-to-point links in standard 3-wire
technology. Both data and diagnostic information as well as power supply are
carried over the serial IO-Link interface simultaneously.

Configuration of IO-Link devices is based on standardized description files "IO
Device Description" (IODD), which are provided by the device manufacturers and
interpreted in the respective configuration software. Thus, IO-Link devices can be
integrated in current automation systems and network structures independent of
the bus systems used.
At the time of creating this documentation, the IO-Link specification
v1.1_Nov2010 is being assumed into the IEC standard and will be standardized as
IEC 61131-9 by "IEC international". The "IO-Link" designation be continued as
"Single-drop digital communication interface for small sensors and actuators"
(SDCI).

The IO-Link Master 750-657 module is used to connect intelligent
actuators/sensors that the IO-Link communication system uses on the control
level. Using 3-wire connection technology, up to four IO-Link devices can be
connected to the individual ports of the IO-Link master.
In addition to the two supply lines L+ and L-, there is another connection (C/Q)
used to transfer process, configuration, parameterization and diagnostic data. The
process data width of an IO-Link device can be between one bit (e.g. simple
switches) and 32 bytes (e.g. complex sensors/actuators).
Transfer is based on 24V levels. Transfer is half-duplex, i.e. data is sent and
received one after the other.
Standard sensor cables can be used. Shielding is not required.
WAGO-I/O-CHECK, function blocks or PROFIBUS-GSD/GSE can be used to
configure and parameterize the IO-Link master.
Two-color LEDs together with the status byte provide information about the
operating status of the individual IO-Link ports.
