1.2 Standards and Guidelines for Operating the 750 Series
Please adhere to the standards and guidelines required for the use of your
system:
• The data and power lines shall be connected and installed in compliance
with the standards required to avoid failures on your system and to
substantially minimize any imminently hazardous situations resulting in
personal injury.
• For assembly, start-up, maintenance and troubleshooting, adhere to the
specific accident prevention provisions which apply to your system (e.g.
BGV A 3, "Electrical Installations and Equipment").
• Emergency stop functions and equipment shall not be made ineffective.
See relevant standards (e.g. DIN EN 418).
• The equipment of your system shall be conform to EMC guidelines so that
any electromagnetic interferences will be eliminated.
• Operating 750 Series components in home applications without further
measures is permitted only if they meet the emission limits (emissions of
interference) in compliance with EN 61000-6-3. You will find the detailed
information in section "WAGO-I/O-SYSTEM 750" ! "System
Description" ! "Technical Data".
• Please observe the safety precautions against electrostatic discharge in
accordance with DIN EN 61340-5-1/-3. When handling the modules,

Safety Information
1.4 Safety Information
When connecting the device to your installation and during operation, the
following safety notes must be observed:
Danger
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 is only permitted via a key or tool to authorized qualified
personnel.
Danger
All power sources to the device must always be switched off before carrying
out any installation, repair or maintenance work.
Warning
Replace defective or damaged device/module (e.g. in the event of deformed
contacts), as the functionality of field bus station in question can no longer be
ensured on a long-term basis.
Warning
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 the
components must be installed in an enclosure that is resistant against the
above mentioned materials. Clean tools and materials are generally required
to operate the device/module.
Warning
Soiled contacts must be cleaned using oil-free compressed air or with ethyl
alcohol and leather cloths.
Warning
Do not use contact sprays, which could possibly impair the functioning of the
contact area.
Warning
Avoid reverse polarity of data and power lines, as this may damage the
devices.
ESD (Electrostatic Discharge)
The devices are equipped with electronic components that may be destroyed
by electrostatic discharge when touched.

System Description
2 The WAGO-I/O-SYSTEM 750
2.1 System Description
The WAGO-I/O-SYSTEM 750 is a modular, field bus independent I/O
system. It is comprised of a field bus coupler/controller (1) and connected
field bus modules (2) for any type of signal. Together, these make up the field
bus node. The end module (3) completes the node.
Fig. 2-1: Field bus node g0xxx00x
Couplers/controllers for field bus systems such as PROFIBUS, INTERBUS,
ETHERNET TCP/IP, CAN (CANopen, DeviceNet, CAL), MODBUS, LON
and others are available.
The coupler/controller contains the field bus interface, electronics and a power
supply terminal. The field bus interface forms the physical interface to the
relevant field bus. The electronics process the data of the bus modules and
make it available for the field bus communication. The 24 V system supply
and the 24 V field supply are fed in via the integrated power supply terminal.
The field bus coupler communicates via the relevant field bus. The
programmable field bus controller (PFC) enables the implementation of
additional PLC functions. Programming is done with the WAGO I/O PRO
CAA in accordance with IEC 61131-3.
Bus modules for diverse digital and analog I/O functions as well as special
functions can be connected to the coupler/controller. The communication
between the coupler/controller and the bus modules is carried out via an
internal bus.
The WAGO-I/O-SYSTEM 750 has a clear port level with LEDs for status
indication, insertable mini WSB markers and pullout group marker carriers.
The 3-wire technology supplemented by a ground wire connection allows for
direct sensor/actuator wiring.

Additionally with the update of a field bus coupler or controller also the cover
of the configuration and programming interface of the coupler or controller is
printed on with the current manufacturing and production order number.
The original manufacturing data on the housing of the component remain
thereby.
2.5 Storage, Assembly and Transport
Wherever possible, the components are to be stored in their original
packaging. Likewise, the original packaging provides optimal protection
during transport.
week 13/2004
When assembling or repacking the components, the contacts must not be
soiled or damaged. The components must be stored and transported in
appropriate containers/packaging. Thereby, the ESD information is to be
regarded.
Statically shielded transport bags with metal coatings are to be used for the
transport of open components for which soiling with amine, amide and
silicone has been ruled out, e.g. 3M 1900E.

2.6.1 Installation Position
Along with horizontal and vertical installation, all other installation positions
are allowed.
Attention
2.6.2 Total Expansion
In the case of vertical assembly, an end stop has to be mounted as an
additional safeguard against slipping.
WAGO item 249-116 End stop for DIN 35 rail, 6 mm wide
WAGO item 249-117 End stop for DIN 35 rail, 10 mm wide
The length of the module assembly (including one end module of 12mm
width) that can be connected to the coupler/controller is 780 mm. When
assembled, the I/O modules have a maximum length of 768 mm.
Examples:
• 64 I/O modules of 12 mm width can be connected to one
coupler/controller.
• 32 I/O modules of 24 mm width can be connected to one
coupler/controller.
Exception:
The number of connected I/O modules also depends on which type of
coupler/controller is used. For example, the maximum number of I/O modules
that can be connected to a PROFIBUS coupler/controller is 63 without end
module. The maximum total expansion of a node is calculated as follows:
Warning
The maximum total length of a node without coupler/controller must not
exceed 780 mm. Furthermore, restrictions made on certain types of
couplers/controllers must be observed (e.g. for PROFIBUS).

2.6.3 Assembly onto Carrier Rail
2.6.3.1 Carrier Rail Properties
All system components can be snapped directly onto a carrier rail in
accordance with the European standard EN 50022 (DIN 35).
Warning
WAGO Kontakttechnik GmbH & Co. KG supplies standardized carrier rails
that are optimal for use with the I/O 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 electro-
magnetic 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) .
• 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) 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, mounting points are to be riveted
under the node in the carrier rail (slotted head captive screws or blind
rivets).

2.6.4 Spacing
The spacing between adjacent components, cable conduits, casing and frame
sides must be maintained for the complete field bus node.
Fig. 2-4: Spacing g01xx13x
The spacing creates room for heat transfer, installation or wiring. The spacing
to cable conduits also prevents conducted electromagnetic interferences from
influencing the operation.

2.6.5 Plugging and Removal of the Components
Warning
Before work is done on the components, the voltage supply must be turned off.
In order to safeguard the coupler/controller from jamming, it should be fixed
onto the carrier rail with the locking disc To do so, push on the upper groove
of the locking disc using a screwdriver.
To pull out the field bus coupler/controller, release the locking disc by
pressing on the bottom groove with a screwdriver and then pulling the orange
colored unlocking lug .
Fig. 2-5: Coupler/Controller and unlocking lug g01xx12e
It is also possible to release an individual I/O module from the unit by pulling
an unlocking lug.

Danger
Ensure that an interruption of the PE will not result in a condition which
could endanger a person or equipment!
For planning the ring feeding of the ground wire, please see chapter 2.6.3.

Mechanical Setup
2.6.6 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 installing.
Starting with the coupler/controller, the bus modules are assembled adjacent
to each other according to the project planning. Errors in the planning 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.
Attention
Always link the bus modules with the coupler/controller, and always plug
from above.
Warning
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.
Always terminate the field bus node with an end module (750-600).

2.6.7 Internal Bus/Data Contacts
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.
Fig. 2-7: Data contacts p0xxx07x
Warning
Do not touch the gold spring contacts on the I/O modules in order to avoid
soiling or scratching!
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. data contacts.

2.6.8 Power Contacts
Self-cleaning power contacts , are situated on the side of the components
which further conduct the supply voltage for the field side. These contacts
come as touchproof spring contacts on the right side of the coupler/controller
and the bus module. As fitting counterparts the module has male contacts on
the left side.
Danger
The male contacts are sharp-edged. Handle the module carefully to prevent
injury.
Attention
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.

Recommendation
With the WAGO ProServe® Software smartDESIGNER, the structure of a
field bus node can be configured. The configuration can be tested via the
integrated accuracy check.

2.6.9 Wire Connection
All components have CAGE CLAMP® connections.
The WAGO CAGE CLAMP® connection is appropriate for solid, stranded
and finely stranded conductors. Each clamping unit accommodates one
conductor.
Fig. 2-9: CAGE CLAMP® Connection g0xxx08x
The operating tool is inserted into the opening above the connection. This
opens the CAGE CLAMP®. Subsequently the conductor can be inserted into
the opening. After removing the operating tool, the conductor is safely
clamped.
More than one conductor per connection is not permissible. If several
conductors have to be made at one connection point, then they should be made
away from the connection point using WAGO Terminal Blocks. The terminal
blocks may be jumpered together and a single wire brought back to the I/O
module connection point.
Attention
If it is unavoidable to jointly connect 2 conductors, then a ferrule must be used
to join the wires together.
Ferrule:

Within the field bus node, there are three electrically isolated potentials.
• Operational voltage for the field bus interface.
• Electronics of the couplers/controllers and the bus modules (internal bus).
• All bus modules have an electrical isolation between the electronics
(internal bus, logic) and the field electronics. Some digital and analog input
modules have each channel electrically isolated, please see catalog.

The ground wire connection must be present in each group. In order that all
protective conductor functions are maintained under all circumstances, it is
recommended that a ground wire be connected at the beginning and end of a
potential group. (ring format, please see chapter 2.8.3). Thus, if a bus module
comes loose from a composite during servicing, then the protective conductor
connection is still guaranteed for all connected field devices.
When using a joint power supply unit for the 24 V system supply and the
24 V field supply, the electrical isolation between the internal bus and the
field level is eliminated for the potential group.

2.7.2 System Supply
2.7.2.1 Connection
The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply
(-15 % or +20 %). The power supply is provided via the coupler/controller
and, if necessary, in addition via the internal system supply modules
(750-613). The voltage supply is reverse voltage protected.
Attention
The use of an incorrect supply voltage or frequency can cause severe damage
to the component.
Fig. 2-11: System Supply g0xxx02e
The direct current supplies all internal system components, e.g.
coupler/controller electronics, field bus interface and bus modules via the
internal bus (5 V system voltage). The 5 V system voltage is electrically
connected to the 24 V system supply.

Attention
Resetting the system by switching on and off the system supply, must take
place simultaneously for all supply modules (coupler/controller and

2.7.2.2 Alignment
Recommendation
A stable network supply cannot be taken for granted always and everywhere.
Therefore, regulated power supply units should be used in order to guarantee
the quality of the supply voltage.
The supply capacity of the coupler/controller or the internal system supply
module (750-613) can be taken from the technical data of the components.

The internal current consumption is indicated in the technical data for each
bus terminal. In order to determine the overall requirement, add together the
values of all bus modules in the node.
Attention
If the sum of the internal current consumption exceeds the residual current
or bus modules, then an internal system supply module (750-613) must be
placed before the module where the permissible residual current was
exceeded.

Example:
A node with a PROFIBUS Coupler 750-333 consists of 20 relay
modules (750-517) and 10 digital input modules (750-405).
Current consumption:
20* 90 mA = 1800 mA
10* 2 mA = 20 mA
Sum 1820 mA
The coupler can provide 1650 mA for the bus modules. Consequently,
an internal system supply module (750-613), e.g. in the middle of the
node, should be added.
Recommendation
With the WAGO ProServe® Software smartDESIGNER, the assembly of a
field bus node can be configured. The configuration can be tested via the
integrated accuracy check.
The maximum input current of the 24 V system supply is 500 mA. The exact
electrical consumption (I

2.7.3 Field Supply
2.7.3.1 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.
The coupler/controller provides field side power (DC 24V). In this case it is a
passive power supply without protection equipment.
Power supply modules are available for other potentials, e. g. AC 230 V.
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.
Fig. 2-13: Field Supply (Sensor/Actuator) g0xxx03e
The supply voltage for the field side is automatically passed to the next
module via the power jumper contacts when assembling the bus modules .
The current load of the power contacts must not exceed 10 A on a continual
basis. The current load capacity between two connection terminals is identical
to the load capacity of the connection wires.
By inserting an additional power supply module, the field supply via the
power contacts is disrupted. From there a new power supply occurs which
may also contain a new voltage potential.
WAGO-I/O-SYSTEM 750
PROFINET IO
Page 38
38 • The WAGO-I/O-SYSTEM 750
Power Supply
Attention
Some bus modules have no or very few power contacts (depending on the I/O
function). Due to this, the passing through of the relevant potential is
disrupted. If a field supply is required for subsequent bus modules, then a
power supply module must be used.
Note the data sheets of the bus modules.
In the case of a node setup with different potentials, e.g. the alteration from
DC 24 V to AC 230V, a spacer module should be used. The optical
separation of the potentials acts as a warning to heed caution in the case of
wiring and maintenance works. Thus, the results of wiring errors can be
prevented.
2.7.3.2 Fusing
Internal fusing of the field supply is possible for various field voltages via an
appropriate power supply module.

Warning
In the case of power supply modules with fuse holders, only fuses with a
maximum dissipation of 1.6 W (IEC 127) must be used.
For UL approved systems only use UL approved fuses.
In order to insert or change a fuse, or to switch off the voltage in succeeding
bus modules, the fuse holder may be pulled out. In order to do this, use a
screwdriver for example, to reach into one of the slits (one on both sides) and
pull out the holder.

2.7.6 Power Supply Unit
The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply
with a maximum deviation of -15 % or +20 %.
Recommendation
A stable network supply cannot be taken for granted always and everywhere.
Therefore, regulated power supply units should be used in order to guarantee
the quality of the supply voltage.
A buffer (200 µF per 1 A current load) should be provided for brief voltage
dips. The I/O system buffers for approx 1 ms.
The electrical requirement for the field supply is to be determined individually
for each power supply point. Thereby all loads through the field devices and
bus modules should be considered. The field supply as well influences the bus
modules, as the inputs and outputs of some bus modules require the voltage of
the field supply.
Attention
The system supply and the field supply should be isolated from the power
supplies in order to ensure bus operation in the event of short circuits on the
actuator side.

2.8 Grounding
2.8.1 Grounding the DIN Rail
2.8.1.1 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.
Attention
Care must be taken to ensure the flawless electrical connection between the
2.8.1.2 Insulated Assembly
carrier rail and the frame or housing in order to guarantee sufficient
grounding.
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 must be set up via an electrical conductor.
The connected grounding conductor should have a cross section of at least
4 mm2.
Recommendation
The optimal insulated setup is a metallic assembly plate with grounding
connection with an electrical conductive link with the carrier rail.
The separate grounding of the carrier rail can be easily set up with the aid of
the WAGO ground wire terminals.

2.8.2 Grounding Function
The grounding function increases the resistance against disturbances from
electro-magnetic interferences. Some components in the I/O system have a
carrier rail contact that dissipates electro-magnetic disturbances to the carrier
rail.
Fig. 2-24: Carrier rail contact g0xxx10e
Attention
Care must be taken to ensure the direct electrical connection between the
carrier rail contact and the carrier rail.
The carrier rail must be grounded.
For information on carrier rail properties, please see chapter 2.6.3.1.

Grounding
2.8.3 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 (PJC). 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.
Attention
Should the ground conductor connection of the power jumper contacts within
the node become disrupted, e. g. due to a 4-channel bus terminal, the ground
connection will need to be re-established.
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.
Fig. 2-25: Ring-feeding g0 xxx07e
Attention
The regulations relating to the place of assembly as well as the national
regulations for maintenance and inspection of the grounding protection must
be observed.

Shielding (Screening)
2.9 Shielding (Screening)
2.9.1 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.
Attention
Constant shielding is absolutely required in order to ensure the technical
specifications in terms of the measurement accuracy.
The data and signal conductors should be separated from all high-voltage
cables.
The cable shield should be potential. With this, incoming disturbances can be
easily diverted.
The shielding should be placed over the entrance of the cabinet or housing in
order to already repel disturbances at the entrance.
2.9.2 Bus Conductors
The shielding of the bus conductor is described in the relevant assembly
guidelines and standards of the bus system.
2.9.3 Signal Conductors
Bus modules for most analog signals along with many of the interface bus
modules include a connection for the shield.
Note
For a better shield performance, the shield should have previously been
placed over a large area. The WAGO shield connection system is suggested
for such an application.
This suggestion is especially applicable if the equipment can have even
current or high impulse formed currents running through (for example
initiated by atmospheric discharge).

modules in the WAGO-I/O-SYSTEM 750/753 on PROFINET IO.
In the initialization phase, the fieldbus coupler determines the physical
structure of the node and creates a local process image with all inputs and
outputs. I/O modules with a bit width smaller than 8 can be combined to form
one byte in order to optimize the address space.
The diagnostics concept is based on channel specific diagnostic messages that
are mapped to the respective alarms. Coding is done according to IEC 61158
(PROFINET IO).
The bus coupler has the following features:
• Process data length
max. 320 byte input data including all user data qualifiers
(max. 2 byte process data qualifiers (IOXS) for each input module)
max. 320 byte output data including all user data qualifiers
(max. 2 byte process data qualifiers (IOXS) for each output module)
• Transfer speed of up to 100 Mbit/s full-duplex, also with autonegotiation
(factory settings)
• Support of all WAGO-I/O-SYSTEM 750/753 I/O modules

The fieldbus coupler takes over the task of the I/O device in PROFINET IO.
This way, an I/O controller can access the process data of the I/O module
periphery after the cyclic exchange of productive data has been successfully
established. Selecting the I/O modules for the process data exchange and
defining the time grid is done when configuring the I/O controller. The
configuration and parameter setting of the fieldbus coupler and I/O modules is
based on the device's GSD file.

Under PROFIBUS IO, the features of the devices are described by the
manufacturer in form of a GSD file and made available to the user. The file is
provided in XML format.
Structure, content and coding of the device specifications are standardized, so
that any I/O devices can be configured using manufacturer-independent tools.

Module slot 0 contains the fieldbus coupler in its function as station substitute.
It does not deliver any process data itself, but provides the parameters required
to perform overall settings of the I/O device.
Slots 1 to max. 128 reflect the physical arrangement of the I/O modules that
deliver a part of the process and/or diagnostics data. Supply modules without
diagnostics, internal system supply module, field side connection module as
well as separation and end modules are not considered during configuration as
they do not provide any process data and/or diagnostics data.
For each I/O module, up to 8 configuration modules are available in the
hardware catalog. The modules are designated by their item number followed
by the number of signal channels, e.g. 75x-467 2AE. Additional information is
included in the module description as different configuration possibilities are
available (see below).
3.1.3.2.1 Configuring Digital I/O Modules
Four digital I/O modules with a granularity smaller or equal to 8 bits are listed
in the I/O device hardware catalog. Three modules reserve 1, 2 or 4 bytes in
the respective area, one of them is used to fill the reserved areas. The 2- and 4byte modules can be found in the hardware catalog under the sub-category
“Word / double word module”. With configuration modules that require more
process image memory than the level of existing information of the respective
I/O modules, the amount of bit information, which is still available in the
allocated area, is indicated in brackets with a positive sign.
The item numbers of the modules, that do not provide a process image
memory but are used to fill previously excessively reserved bit information,
are marked with a star (*). Furthermore, the module names, that are
represented with a negative sign in brackets, contain the amount of
information that has been previously allocated in the area of the process image
by the I/O module.

3.1.3.4 Station Naming
3.1.3.4.1 Device Name Assignment via Configuration Tool
The fieldbus coupler (I/O Device) can be clearly identified using its device
name within a PROFINET IO network. The device name enables the I/O
controller to allocate the device with an IP address for establishing the
productive data exchange when starting the system. The I/O device receives
the device name during configuration (station naming) and saves it
permanently. The device name is transferred using Discovery and basic
Configuration-Protocol (DCP). The device is activated using the Ethernet
address (MAC address).
3.1.3.4.2 Device Name Assignment via DIP Switch Settings
In addition to assigning a name via a configuration tool, a device name
instance based on the "wago 750 370" or "wago io device" specified strings
can be allocated to the device via the DIP switch setting. This kind of station
naming is enabled by setting switch 8 to "ON". Selecting the desired string is
performed via switch 7. The device name instance is constructed using the
following rule:

3.1.4 Initialization Phase of the Fieldbus Coupler
The communication system can be commissioned after the PROFINET IO
system has been configured, the I/O devices have been installed and a name
has been given to the station.
After the power supply has been switched on, the fieldbus coupler initializes
the internal communication system. In the phase where the I/O LED flashes
red with 10 Hz, the arranged I/O modules are determined and are allocated to
the PROFINET IO process image according to the standard defaults of the bus
coupler. After a trouble free start that is displayed using a green lit “I/O” LED,
the coupler changes to the condition “Fieldbus start” where it then waits for
the connection build-up of the I/O controller. If the coupler upload procedure
was not carried out with success then the red I/O LED signals the cause of
failure through a flashing cycle. The cause of failures can be obtained in
chapter 3.1.11.1.

3.1.5 Process Image
3.1.5.1 Local Process Image
After being switched on, the coupler identifies all I/O modules connected that
supply or receive process data (data width or bit width > 0).
Note
For the number of input and output bits or bytes of the individual I/O
modules please refer to the corresponding description of the I/O modules.
The fieldbus coupler allocates the user data of the connected I/O modules
according to specified rules to the local input and output image. The allocation
is carried out according to the slots. Digital I/O modules with a data width less
than 8 bits are always opened with one bit in the respective process image
area.
After a successful configuration test while establishing the connection, if there
is any difference between the user configuration and the process image
generated during start up, a new process image is created according to the user
configuration. One of the reasons for this may be the packing of digital I/O
modules or the lack of configuration modules for the connected I/O modules
during configuration.

3.1.5.2 Allocation of the Input and Output Data
The process data is exchanged via the PROFINET IO using the higher ranking
controls. A maximum of 320 bytes of output data (including all IOPS and
IOCS) can be transferred from the I/O controller to the bus coupler. The bus
coupler sends a maximum of 320 byte of input data (including all IOPS and
IOCS) to the I/O controller.
When configuring a node, the individual modules are configured in
accordance with their physical arrangement (slot orientated). These modules
can be taken over from a hardware catalog of the configuration tool. All
specific information on the relevant modules is contained in the associated
GSD file.

In productive data exchange, one or two byte IOXS process data qualifiers are
available for each configuration module providing information of the validity
of the module data. The process data qualifiers are an integral part of the
maximum length of the telegram of 320 bytes and must therefore be
considered when mounting the modules.

PROFINET IO 750-370 • 87 Configuration and Parameter Setting of I/O Modules
3.1.5.4 Establishing the Connection
Before starting the productive data exchange between the I/O controller and
the I/O device, individual communication instances are created within the
PROFINET IO context management and the I/O configuration (target
configuration) of the modules is notified. After the connection structure has
been checked and once the actual configuration has been adjusted (optional),
the I/O device receives all necessary operating settings (parameters) so that
the cyclic data exchange via “record data” sets can be established. Both the
buscoupler and the connected I/O modules are supplied with parameters. Once
all settings have been made, the I/O device signals that it is ready to send and
receive cyclic productive data.
3.1.6 Configuration and Parameter Setting of I/O Modules
Setting the parameters of I/O modules is performed via “record data” sets.
Modules with diagnostics capability allow the diagnostics message to be
locked or released for each channel. Digital outputs provide the possibility of
switching a configurable substitute value for each channel in the case of
invalid output information.
Possible configuration and parameter values can be found in chapter 5.3,
„Configuration and Parameter Setting of the Modules“.
Note
For simplification, only the item numbers are shown as module designation in
the table. Therefore, the module “75x-400” corresponds to module “750-400
2 DI/24 V DC/3.0 ms” or “753-400 2 DI/24 V DC/3.0ms”.

3.1.7.1 Diagnostics Data Sets
The diagnostics information of the buscoupler (I/O device) can be read out
acyclically using standard diagnostics data sets (records). The structure of the
data sets is defined in the PROFINET IO specification (see IODReadReq or
IODReadRes). The data set number (index) allows to distinguish between the
diagnostics level and the diagnostics structures.
The following diagnostics data sets can be requested in case of an upcoming
diagnostics message:

3.1.7.2 Structure of the Standardized Diagnosis Data Sets
The diagnosis data sets comprise of several structure elements. The first
element in the data set is the head of the structure. It describes the version and
the length of the following data. An identifier (BlockType)specifies the
structure of the diagnosis data. The following identifiers are currently used by
the buscoupler:

The process type API has a data length of 4 bytes. Depending on the version
of the data set, the diagnostics data follow with Byteoffset 6 (Version 1.0) or
Byteoffset 10 (Version 1.1). However, the description of the diagnostics data
in the sub-chapters - depending on the BlockType - begins back with
Byteoffset 0.
3.1.7.2.1 Channel Specific Diagnostics
Errors occurring when configuring and setting the parameters of the station
(I/O device) and the connected I/O modules as well as external errors from the
connected periphery are reported by the coupler via channel specific
diagnostics. External errors reported by the subassemblies (e.g. short circuits,
line interruptions) are only transmitted to the I/O controller after release when
setting the module's parameters.

Diagnostics
The BlockType in the head structure of the data set corresponds to the value
for the channel diagnostics (0x0010). The length defines the following
diagnostics data for faulty sub-modules or channels.
The data for the channel diagnostics is triggered using a general structure (see
ChannelDiagnosis or ExtChannelDiagnosis), which is followed by
the fault indication of the respective channels. The general structure has a
length of 10 bytes and is composed of as follows:
Byteoffset

Sub-module slot for the alarm source = 1
ID of the alarm source = sub module (0x8000)
Fault type = upcoming fault (0x08)
Reserved (0x00)
Fault type = diagnostics for the sub module
As already mentioned, special data sets of faulty sub-modules or channels are
following the general structure. This information may be repeated depending
on how many different fault messages exist for the channels of a sub-module.
The number of existing channel diagnostics data sets can be determined using
the length indicated in the head structure.
The following sub-chapters describe the standardized and extended channel
diagnostics information that is supported by the coupler.
3.1.7.2.1.1 Channel Diagnostics
The channel diagnostics is set by the coupler when external channel faults
occur (e.g. short circuits or overvoltage). These types of faults are defined in
the PROFINET IO specification.
The fault type (SubStructureDefined) contains the value for channel
diagnostics (0x8000).
Each fault of a signal channel or sub-module is described in a data set (see
ChannelDiagnosisData). The structure of the data set has 6 bytes and is
composed of as follows:

3.1.7.2.2.1 Extended Channel Diagnostics
The buscoupler uses the extended channel diagnostics to signal internal bus,
configuration and parameter setting faults. According to the PROFINET IO
standard, extended fault information must be expressed according to the
manufacturer specifications.
The fault type (UserstructureIdentifier) has the value for the
extended channel diagnostics (0x8002).
The structure for the data set (see ExtChannelDiagnosisData) has 12
bytes and is composed of as follows:

The following tables describe the possible fault messages that are based on the
combination of fault type, extended fault type and additional value. The “xx”
symbols used for some additional values represent the signal channel
(0x0000 ... 0x0007) where the fault has been detected.
The faults described in the following table are faults occurring when
configuring both the station substitute (buscoupler) and the modules (I/O
modules). Configuration faults are coded using fault type 0x0010 in
accordance with the PROFINET IO standard.
