•Installation only in appropriate housings, cabinets or in electrical operation rooms!
The I/O modules and its components are an open system. As such, install the system and its
components exclusively in appropriate housings, cabinets or in electrical operation rooms. Allow
access to such equipment and fixtures to authorized, qualified staff only by means of specific
keys or tools.
•Replace defective or damaged devices!
Replace defective or damaged device/module (e.g., in the event of deformed contacts), since the
long-term functionality of fieldbus station involved can no longer be ensured.
The following figure shows the principle I/O Module System for Infrared Linescanners and Thermal Imagers based
on a modular I/O system.
Figure 1-1: I/O Module System for the Infrared Device (Principle)
It is comprised of a fieldbus coupler (1) and connected fieldbus modules (2) for any type of signal. Together, these
make up the fieldbus node. The end module (3) completes the node.
Figure 1-2: I/O Fieldbus Coupler with I/O Modules, Example
Bus modules for diverse digital and analog I/O functions can be connected to the fieldbus coupler. The
communication between the coupler and the bus modules is carried out via an internal bus.
You must take care to ensure the flawless electrical connection between the carrier rail and the
frame or housing in order to guarantee sufficient grounding.
Users Manual, Rev. 1.1, May 2018
1.2.2 Field Supply
1.2.2.1 Connection
Sensors and actuators can be directly connected to the relevant channel of the bus module in 1/4 conductor
connection technology. The bus module supplies power to the sensors and actuators. The input and output drivers
of some bus modules require the field side supply voltage.
For the field side power, a power supply module is necessary. Likewise, with the aid of the power supply modules,
various potentials can be set up. The connections are linked in pairs with a power contact.
Figure 1-4: Field Supply (sensor/actuator)
In exceptional instances, I/O modules can be directly connected to the field supply!
The 24 V field supply can be connected also directly to a bus module, if the connection points are not
needed for the peripheral device supply. In this case, the connection points need the connection to the
power jumper contacts.
1.3 Grounding
1.3.1 Grounding the DIN Rail
1.3.1.1 Framework Assembly
When setting up the framework, the carrier rail must be screwed together with the electrically conducting cabinet
or housing frame. The framework or the housing must be grounded. The electronic connection is established via
the screw. Thus, the carrier rail is grounded.
You must take care to ensure the direct electrical connection between the carrier rail contact
and the carrier rail. The carrier rail must be grounded.
1.3.1.2 Insulated Assembly
Insulated assembly has been achieved when there is constructively no direct conduction connection between the
cabinet frame or machine parts and the carrier rail. Here the earth ground must be set up via an electrical conductor
accordingly valid national safety regulations.
Recommendation
The optimal setup is a metallic assembly plate with grounding connection with an electrical conductive link
with the carrier rail.
1.3.2 Grounding Function
The grounding function increases the resistance against disturbances from electromagnetic interferences. All
components for the I/O module system have a carrier rail contact that dissipates electro-magnetic disturbances to
the carrier rail.
Figure 1-5: Carrier Rail Contact
Grounding
1.3.3 Grounding Protection
For the field side, the ground wire is connected to the lowest connection terminals of the power supply module.
The ground connection is then connected to the next module via the Power Jumper Contact. If the bus module has
the lower power jumper contact, then the ground wire connection of the field devices can be directly connected to
the lower connection terminals of the bus module.
Re-establish the ground connection when the connection to the power jumper contacts is disrupted!
Should the ground conductor connection of the power jumper contacts within the node become disrupted, e.
The ring feeding of the grounding potential will increase the system safety. When one bus module is removed from
the group, the grounding connection will remain intact. The ring feeding method has the grounding conductor
connected to the beginning and end of each potential group.
You must observe the regulations relating to the place of assembly as well as the national regulations for
g. due to a 4-channel bus terminal, the ground connection will need to be re-established.
Figure 1-6: Ring-feeding
Observe grounding protection regulations!
maintenance and inspection of the grounding protection.
1.4 Shielding (Screening)
1.4.1 General
The shielding of the data and signal conductors reduces electromagnetic interferences thereby increasing the
signal quality. Measurement errors, data transmission errors and even disturbances caused by overvoltage can
be avoided.
Lay the shielding throughout the entrance and over a wide area!
Constant shielding is absolutely required in order to ensure the technical specifications in terms of the
measurement accuracy.
The cable shield should be potential. With this, incoming disturbances can be easily diverted.
You should place shielding over the entrance of the cabinet or housing in order to already repel disturbances
at the entrance.
Lay high-voltage cables separately!
Separate the data and signal conductors from all high-voltage cables.
1.4.2 Bus Conductors
The shielding of the bus conductor is described in the relevant assembly guidelines and standards of the bus
system.
1.4.3 Signal Conductors
Bus modules for most analog signals along with many of the interface bus modules include a connection for the
shield.
Improve shield performance by placing the shield over a large area!
For a better shield performance, you should place the shield previously over a large area.
The 750-352 fieldbus coupler connects the I/O Module System with the infrared device via Ethernet.
Equipped with two RJ-45 ports, which both work as 2-channel switches, the fieldbus coupler enables easy and
cost-effective cabling.
With the DIP switch the last byte of the IP address, as well as the assignment of the IP address (BootP, firm setting)
can be given.
In the fieldbus coupler, all input signals from the sensors are combined. After connecting the fieldbus coupler, the
fieldbus coupler determines which I/O modules are on the node and creates a local process image from these.
The data of the analog modules is mapped first into the process image. The modules are mapped in the order of
their physical position after the coupler. The digital modules are then mapped after the analog ones in the process
image.
Process data linking is performed in the PC software for the infrared devicece automatically.
2.1 View
The view below shows the different parts of the device:
• The fieldbus connection is within the lower range on the left side.
• Over the fieldbus connection is a power supply unit for the system supply.
• LEDs for bus communication, error messages and diagnostics are within the upper range on the right
side.
•Downright the service interface is to be found.

2.2 Connectors
2.2.1 Device Supply
The device is powered via terminal blocks with CAGE CLAMP® connections. The device supply generates the
necessary voltage to power the electronics of the device and the internal electronics of the connected I/O modules.
The fieldbus interface is galvanically separated from the electrical potential of the device via the transducer.
The connection to the fieldbus is made via two RJ-45 plugs, which are connected to the fieldbus controller via an
integrated switch.
The integrated switch works in store-and-forward operation and for each port, supports the transmission speeds
10/100 Mbit as well as the transmission modes full and half-duplex and auto-negotiation. The wiring of these plugs
corresponds to the specifications for 100BaseTX, which prescribes a category 5 twisted pair cable as the
connecting cable. Cable types S-UTP (Screened Unshielded Twisted Pair) and STP (Shielded Twisted Pair) with
a maximum segment length of 100 m (328 ft) can be used. The RJ-45 socket is physically lower, allowing the
coupler to fit in an 80 mm (3.1 in) high enclosure once connected.

2.3.2 Fieldbus Status
The health of the ETHERNET fieldbus is signaled through the top LED group (“LINK ACT 1”, “LINK ACT 2”, “MS”,
and “NS”). The two-colored LED’s “MS” (module status) and “NS” (network status) are solely used by the
Ethernet/IP protocol. These two LED’s conform to the Ethernet/IP specifications.
Table 2-4: Fieldbus Diagnostics
2.3.3 Node Status
The communication status between fieldbus coupler/controller is indicated by the “I/O” LED.
Table 2-5: Node Status Diagnostics
Device boot-up occurs after turning on the power supply. The I/O LED is orange.
After a trouble-free start-up, the I/O LED is green.
In the event of an error, the I/O LED continues to blink red. Blink codes indicate detailed error messages. An error
is indicated cyclically by up to 3 blinking sequences.
After elimination of the error, restart the node by turning the power supply of the device off and on again.
The configuration of the IP address via the address selection switch takes place when you set the host ID (last
digit of the IP address). The coding of the host ID is bit by bit and begins with address selection switch 1 for bit 0
(LSB) and ends with address selection switch 8 for bit 7 (MSB). The base address used depends on the IP address
currently saved in the coupler.
With the original factory settings, the IP address is configured to the value 0.0.0.0 by default. In this case, the static
base address 192.168.42.x is used.
Along with horizontal and vertical installation, all other installation positions are allowed. In the case of vertical
assembly, an end stop has to be mounted as an additional safeguard against slipping.
3.2 Total Extension
The length of the module assembly (including one end module of 12 mm/0.47 in width) that can be connected to
the fieldbus coupler is 780 mm (31 in). When assembled, the I/O modules have a maximum length of 768 mm
(30 in).
Examples:
• 64 I/O modules of 12 mm (0.47 in) width can be connected to one coupler/controller.
• 32 I/O modules of 24 mm (0.94 in) width can be connected to one coupler/controller.
3.3 Assembly onto Carrier Rail
3.3.1 Carrier Rail Properties
All system components can be snapped directly onto a carrier rail in accordance with the European standard
EN 50022 (DIN 35).
Do not use any third-party carrier rails without approval by WAGO!
The manufacturer supplies standardized carrier rails that are optimal for use with the I/O module system. If
other carrier rails are used, then a technical inspection and approval of the rail by WAGO Kontakttechnik
GmbH & Co. KG should take place.
Carrier rails have different mechanical and electrical properties. For the optimal system setup on a carrier rail,
certain guidelines must be observed:
• The material must be non-corrosive.
• Most components have a contact to the carrier rail to ground electromagnetic disturbances. In order to
avoid corrosion, this tin-plated carrier rail contact must not form a galvanic cell with the material of the
carrier rail which generates a differential voltage above 0.5 V (saline solution of 0.3% at 20°C/68°F).
•The carrier rail must optimally support the EMC measures integrated into the system and the shielding of
the bus module connections.
•A sufficiently stable carrier rail should be selected and, if necessary, several mounting points (every 20
cm/7.9 in) should be used in order to prevent bending and twisting (torsion).
•The geometry of the carrier rail must not be altered in order to secure the safe hold of the components.
In particular, when shortening or mounting the carrier rail, it must not be crushed or bent.
•The base of the I/O components extends into the profile of the carrier rail. For carrier rails with a height
of 7.5 mm (0.3 in), mounting points are to be riveted under the node in the carrier rail (slotted head captive
screws or blind rivets).
•The medal springs on the bottom of the housing must have low-impedance contact with the DIN rail (wide
contact surface is possible).
The male contacts are sharp-edged. Handle the module carefully to prevent injury.
Connect the I/O modules in the required order!
Never plug bus modules from the direction of the end terminal. A ground wire power contact,
which is inserted into a terminal without contacts, e.g. a 4-channel digital input module, has a
decreased air and creepage distance to the neighboring contact in the example DI4.
Assemble the I/O modules in rows only if the grooves are open!
3.4 Spacing
The spacing between adjacent components, cable conduits, casing and frame sides must be maintained for the
complete fieldbus node.
Figure 3-1: Spacing
Spacing
The spacing creates room for heat transfer, installation or wiring. The spacing to cable conduits also prevents
conducted electromagnetic interferences from influencing the operation.
3.5 Assembly Sequence
All system components can be snapped directly on a carrier rail in accordance with the European standard
EN 50022 (DIN 35).
The reliable positioning and connection is made using a tongue and groove system. Due to the automatic locking,
the individual components are securely seated on the rail after installation.
Starting with the fieldbus coupler, the bus modules are assembled adjacent to each other according to the project
design. Errors in the design of the node in terms of the potential groups (connection via the power contacts) are
recognized, as the bus modules with power contacts (male contacts) cannot be linked to bus modules with fewer
power contacts.
Please take into consideration that some bus modules have no or only a few power jumper
contacts. The design of some modules does not allow them to be physically assembled in
rows, as the grooves for the male contacts are closed at the top.
Use caution when interrupting the PE!
Make sure that people or equipment is not placed at risk when removing an I/O module and the
associated PE interruption. To prevent interruptions, provide ring feeding of the ground
conductor.
Perform work on devices only if the system is de-energized!
Working on devices when the system is energized can damage the devices. Therefore, turn off
the power supply before working on the devices.
Users Manual, Rev. 1.1, May 2018
Always plug a bus end module 750-600 onto the end of the fieldbus node to guarantee proper data transfer.
3.6 Inserting and Removing Devices
Don't forget the bus end module!
3.6.1 Inserting the Fieldbus Coupler
1. When replacing the fieldbus coupler for an already available fieldbus coupler, position the new fieldbus
coupler/controller so that the tongue and groove joints to the subsequent I/O module are engaged.
2. Snap the fieldbus coupler/controller onto the carrier rail.
3. Use a screwdriver blade to turn the locking disc until the nose of the locking disc engages behind the
carrier rail (see the following figure). This prevents the fieldbus coupler from canting on the carrier rail.
With the fieldbus coupler snapped in place, the electrical connections for the data contacts and power contacts (if
any) to the possible subsequent I/O module are established.
1. Use a screwdriver blade to turn the locking disc until the nose of the locking disc no longer engages
behind the carrier rail.
2. Remove the fieldbus coupler/controller from the assembly by pulling the release tab.
Electrical connections for data or power contacts to adjacent I/O modules are disconnected when removing the
fieldbus coupler/controller.
3.6.3 Inserting I/O Module
1. Position the I/O module so that the tongue and groove joints to the fieldbus coupler or to the previous or
possibly subsequent I/O module are engaged.
Figure 3-3: Insert I/O module
2. Press the I/O module into the assembly until the I/O module snaps into the carrier rail.
Figure 3-4 Snap the I/O module into place
With the I/O module snapped in place, the electrical connections for the data contacts and power contacts (if any)
to the fieldbus coupler or to the previous or possibly subsequent I/O module are established.
The male contacts are sharp-edged. Handle the module carefully to prevent injury.
Data Contacts / Internal Bus
4 Connect Devices
4.1 Data Contacts / Internal Bus
Communication between the coupler/controller and the bus modules as well as the system supply of the bus
modules is carried out via the internal bus. It is comprised of 6 data contacts, which are available as self-cleaning
gold spring contacts.
Figure 4-1: Data Contacts
4.2 Power Contacts / Field Supply
Self-cleaning power jumper contacts used to supply the field side are located on the right side of both couplers
and some of the I/O modules. These contacts come as touch-proof spring contacts. As fitting counterparts the I/O
modules have male contacts on the left side.
This chapter shows a step-by-step procedure for starting up exemplarily a fieldbus node.
Good example!
This description is just an example and only serves to describe the procedure for a local start-up of a single
fieldbus node with a non-networked computer under Windows.
Two work steps are required for start-up. The description of these work steps can be found in the corresponding
following sections.
• Connecting client PC and fieldbus nodes
• Assigning the IP address to the fieldbus node
The IP address must occur in the network only once!
For error-free network communication, note that the assigned IP address must occur only once in the
network! In the event of an error, the error message "IP address configuration error" (error code 6 - error
argument 6) is indicated by 'I/O' LED at the next power-on.
There are various ways to assign the IP address. The various options are described in the following sections
individually.
5.1 Connecting Client PC and Fieldbus Nodes
1. Mount the fieldbus node on the TS 35 carrier rail. Follow the assembly instructions found see section
3 Assembly, page 22.
2. Connect the 24V power supply to the supply terminals.
3. Connect the PC's Ethernet interface to the fieldbus coupler's Ethernet interface.
4. Turn the operating voltage on.
The fieldbus coupler is initialized. The coupler determines the I/O module configuration and creates a process
image. During start-up, the I/O LED (red) flashes. If the I/O LED lights up green after a brief period, the fieldbus
coupler is operational. If an error has occurred during startup, a fault code is flashed on the I/O LED.
5.2 Allocating the IP Address to the Fieldbus Node
• Assigning IP Address via BootP server
• Use address selection switch (DIP switch) to assign IP address (manually).
5.2.1 Assigning the IP Address with a BootP Server
A BootP server can be used to assign a fixed IP address. The BootP server capability is managed by the PC
software of the infrared device and is set as the default address mode.
Set the address selection switch to 0!
Set the address selection switch to 0 to disable the DIP switch and to enable the software configuration via
BootP. Restart the fieldbus node after adjusting the address selection switch to apply the configuration
changes.
To assign a fixed IP address via a BootP server, the MAC ID must be known to the PC software. The MAC ID is
applied to the back of the fieldbus coupler or on the selfadhesive peel-off strip on the side of the fieldbus coupler.
MAC ID of the fieldbus coupler: 0 0 : 3 0 : D E : _ _ : _ _ : _ _
5.2.2 Assigning IP Address via Address Selection Switch
Use the address selection switch to set the host ID, i.e., the last byte ("X") of the IP address saved in the fieldbus
coupler with values between 1 and 254 binary coded.
Example:
IP address saved in the fieldbus coupler: 192.168.42.20
Set DIP switch value: 50 (binary coded: 00110010)
Resulting IP address: 192.168.42.50
Use the address selection switch to set the last byte ("X") of the IP address to a value between 1 and 254.
The DIP switch is then enabled and the IP address is composed of the base address stored in the fieldbus
Address selection switch values 0 and 255 are predefined, address selection switch disabled!
f you use the address selection switch to set the value 0 or 255, the address selection switch is disabled and
the setting configured in the fieldbus coupler is used. With the value 0, the settings of the BootP server
apply. If you set the value 255, the configuration via DHCP would be activated but is not supported with the
The base address used consists of the first three bytes of the IP address. This always depends on the IP address
currently saved in the fieldbus coupler.
If there is still no static IP address in the fieldbus coupler, the default value 192.168.42.X defined by the firmware
as the base address is used when setting the DIP switch to 1 - 254. The address selection switch setting then
overwrites the value of the host ID "X".
1. To configure the IP address via the address selection switch by setting the host ID (last position of the IP
address) to a value that does not equal 0/255, first convert the host ID to the binary representation. For
example, host ID 50 results in a binary code of 00110010.
2. Set the bits in sequence using the 8 address switches. Start with address switch 1 to set bit 0 (LSB) and
end with address switch 8 for bit 7 (MSB).
Host ID 1 - 254 via address selection switch freely adjustable!
coupler and the host ID set on the DIP switch.

changes.
5.3 Restoring Factory Settings
To restore the factory settings, proceed as follows:
1. Switch off the supply voltage of the fieldbus coupler.
2. Connect the communication cable 750-920 to the configuration interface of the fieldbus coupler and to a
vacant serial port on your computer.
3. Switch on the supply voltage of the fieldbus coupler.
4. Start the WAGO-ETHERNET-Settings program.
5. In the top menu bar, select <Default> and click [Yes] to confirm.
A restart of the fieldbus node is implemented automatically. The start takes place with the default settings.
The digital output module provides 16 channels. A green LED indicates the switched status of each channel. An
optocoupler provides electrical isolation between the bus and the field side.

The analog output module 750-562 generates output voltages ranging from 0–10 V for the field. The output range
is preset by the manufacturer but can be changed later via WAGO-I/O-CHECK. The module has two short circuitproof output channels and enables direct connection of two 2-line actuators on the connections AO 1 and ground
or AO 2 and ground. Signals are output via AO 1 or AO 2. In addition, the sense lines from 4-line actuators can be
connected to the connections Sense AO1 and +Sense AO1 or Sense AO2 and +SenseAO2. Both output channels
have a common ground potential. The output signal is electrically isolated.

The 2-channel passive isolator filters and electrically isolates 0(4)–20 mA analog standard signals, while drawing
power for signal transmission from the input circuit. The connected sensor supplies the passive isolator with the
required power, while powering the connected load.
Characteristics:
• No additional supply voltage required
• Safe 3-way isolation with 2.5 kV test voltage to EN 61140
The digital input module provides 16 channels. A green LED indicates the switched status of each channel. An
optocoupler provides electrical isolation between the bus and the field side.
The supply module provides the I/O modules with the corresponding supply potential. The maximum current at the
supply module is 10 A. When configuring the system, it must be ensured that this total current is not exceeded.
Should higher currents be necessary, intermediate supply modules must be added in the assembly.
After the fieldbus node is assembled with the correct bus coupler and I/O modules, the end module is snapped
onto the assembly. It completes the internal data circuit and ensures correct data flow.
