1.1. SAI
The acronym SAI stands for Sensor Actuator Interface.
It is a compact-designed distributor and collector of
signal lines.
Signals to and from the process in field installations are
often controlled from a central point, for example, by a
PLC or industrial PC. Typically, the distance between
the installation and the central controls is significant.
The resulting costs for installation and materials for the
cabling are high. This in turn increases the susceptibility
of the system to interference and errors.
The use of SAIs has proven successful under numerous conditions:
•
The signal lines of the peripheral devices are bundled together at the process in the installation and
connected to a bus.
•
Signal lines are connected simply and conveniently
by means of Plug and Play.
•
The controls are at a central point
•
The reliability of the data transfer is guaranteed by
a bus system.
The SAI consists of the following components:
•
An I/O section: to connect the signal lines.
•
A settings section:
to set the network addresses and insert the jumpers for the different electric potentials.
•
A bus / power section: for the connection and loop
through for the supply voltage as well as the bus
connection.
Weidmüller offers the following I/O versions:
•
M12 16DI with 16 digital inputs.
•
M12 16DI / 8DO with 8 fixed digital inputs and 8
individually configurable inputs or outputs.
In addition, Weidmüller also offers:
•
Network components for the Fieldbus systems
mentioned above
•
Sensor / valve connector cables
•
Plug-in connectors and twin-plugs
•

1.2. PROFIBUS-DP
PROFIBUS
PROFIBUS (PROcess Field BUS) is a part of the international IEC 61158 and IEC 61784 standards.
Physically, PROFIBUS is either an electrical network
based on a shielded, two-conductor cable or an optical
network based on a fibre optics cable. PROFIBUS-DP
(DP = Decentralised Periphery) is a special application
for automating factory production.
System
A typical PROFIBUS-DP system is made up of:
•
At least one PLC or industrial PC (master) operating as a control system.
•
Various field devices, such as digital or analogue
I/O devices, AC or DC drives, magnetic or pneumatic valves, frequency converters, starters, operating and indicating devices (slaves).
GSD files (device database files)
The GSD file is the obligatory ‘ID card’ of each and
every PROFIBUS device. It contains the characteristic
data of the device, details about its communication
capabilities as well as other information, such as diagnostic values.
Weidmüller has made available for downloading all
GSD files of the SAI distributors from the SAI Active
Universal series – at: http://www.weidmueller.com.
For more information, please refer to Chapter 5 (Commissioning).
Data transfer
Data exchange within the system is carried out by
means of cyclic polling. The master establishes communications with one slave at a time and makes data
available and/or requests data. The slave being addressed responds immediately to the request for data.
Once completed, this procedure is repeated with the
other slave devices. This is a continuous cyclic process.

1.3. Bluetooth
Bluetooth
Bluetooth defines a universal wireless interface in the
2.4 GHz ISM band. No license is required for the 2.4
GHz ISM band. Users are not required to register or
pay usage fees.
The acronym ISM stands for Industrial Scientific Medical and describes the potential scope of its use. A
range between 10 metres to 100 metres is defined
because of Bluetooth's minimal transmitting power of a
few milliwatts.
System
A Bluetooth system consists of a maximum of 255
nodes. From these however, only 8 can be simultaneously connected to each other.
The Weidmüller Bluetooth SAIs are formed from Piconets consisting of one master and six slaves. Thirty-two
of these Piconets can be operated in parallel.
The Bluetooth master, which functions as the
PROFIBUS gateways, is simultaneously a slave in the
PROFIBUS system. The PROFIBUS master views it as
a standard PROFIBUS slave with a modular I/O configuration. The Bluetooth gateway can be configured
with a GSD file.
Protocol
The standard Bluetooth profile is used. The communication protocol then uses this. The implementation is
based on the CANopen / WIRELESSopen standards.

2.1. Project planning
Planning the bus system
The following steps must be taken into consideration when designing an installation:
•
•
•
•
•
Location of the machine or facility
Assignment of the signals to the installation to a logical group
Selection of the field devices
Assignment of the signals to the field devices
Determination of where the field devices are to be installed
Criteria for determining the correct SAI distributor:
Size of the connectors
Determine the size of the connectors to suit your application, the design of the sensors or according to your personal preferences. Weidmüller offers both M12 and M8
variants for purely digital signals
Number of poles of
the I/O connections
Please consider the sensor/actuator cable to be connected; possible options are 3
or 5 poles
Y-piece (twin)
Specifically for 5-pole M12 sensor connections, you can feed two cables to a distributor input by means of a Y-piece.
Inputs / outputs
Weidmüller has a variety of SAI distributors on offer such as a variant with 16 digital
inputs, with mixed digital inputs/outputs as well as an analogue/digital version (for
more information please refer to Chapter 4 (Connecting SAIs).
Shielding
Shielding by means of metal connectors is necessary for bus connections. We recommend the same approach for analogue signals to restrict the susceptibility to
interference.
Signals
Please consider if you wish to transmit analogue or digital signals.

2.2. Power supply
Star or line topology wiring can be used to feed the
power supply. Only modules without digital outputs are
suitable for line topology wiring.
Example calculation to determine voltage drop in
the lines:
Power is supplied via the plug in connection AUX IN;
power is fed to the next module via the module connection AUX OUT.
Caution
The maximum current supplied to the first
module must not exceed 2.5 A per power
supply pin. The supply voltage at the last
module must not fall below 18 V DC.
When determining the maximum number of
modules in series you should take into consideration the total current of all modules and
the voltage drop in the line.
Voltage drop in the lines:
(Line resistance) x (total length of line) x (2)
Total current of the modules:
Power consumption modules + total current of the consumers
Figure 4: Voltage drop
Voltage drop to module 1
(line resistance x length of line L1 x 2) x current consumption

Note
Please observe that a given distance to the
adjacent module may be required when
using custom assembly and angled connectors.
An SAI distributor can be mounted in any position.
There are no restrictions placed with regard to their
position when being mounted: vertical, horizontal, on
their side, or overhead. However, to ensure that the
LEDs can be seen, we recommend that – where possible – the modules are not mounted on their side or
overhead. Our SAIs can be mounted side by side.
The mounting dimensions of our SAI distributors are
210 x 54 mm.
You can find details about the mounting dimensions in Appendix B: Drilling Templates.

3.2. Mounting SAI distributors
Mounting
To mount the SAI distributor, select a firm and level
surface. Pre-drill the bore holes (for more information,
please refer to Appendix B: Drilling Template). Hold the
distributor above the bore holes and fix it in positions
with screws. Please use a spring washer if the SAI
distributor is to be used in an environment where the
loads are subject to increased shock and vibration.
Please refer to Figure 5: Mounting dimensions for the
SAI Active Universal.
PROFIBUS guidelines
Please observe the PROFIBUS guidelines: Installation
Guideline for PROFIBUS-DP/FMS.
Functional earth (FE)
The functional earth is the earthing (ground) of equipment to its surroundings. Contrary to the protective
earth (PE) the FE does not primarily serve to protect
equipment or persons, but instead serves to discharge
electrostatic charges and shield connections.
Caution
Electromagnetic pulses affect cabling and
the distributor during operations. Flawed
signals and false data can result.
Do not use a PE conductor for the FE connection.
SAI distributors from the SAI Active Universal series are
equipped with an FE connection integrated at the
mounting hole in the bus/power section. Use this connection and fix the distributor directly to a conductive
surface or attach a short, low impedance FE cable to
the fixing screw by means of a cable lug. Please refer
to Figure 6: Mounting an SAI distributor.

3.4. Setting the PROFIBUS address
PROFIBUS address
The PROFIBUS address is used to determine at which
address your SAI distributor will be identified on
PROFIBUS-DP.
Setting
Set the PROFIBUS-DP address for the SAI distributor
in the settings section of the distributor. Use a flatbladed screwdriver to adjust the rotary switch.
Tools
Use a 2.5-mm flat-bladed screwdriver (please refer to
Appendix A: Overview of items).
Address / hexadecimal code
Please note that PROFIBUS-DP allows a maximum of
126 possible addresses. The addresses 1 to 125 are
defined. Please note that the address 126 is used for
configuration purposes and the addresses 01 and 02
are retained for the PROFIBUS master. The distributor
address is set in hexadecimal code by means of two
rotary coding switches. To do so, you will have to convert the decimal address to hexadecimal or, for the
sake of simplicity, you could make use of the table
below.
Example:
To set the PROFIBUS-DP address 93, turn the lefthand rotary coding switch to position 5 and the righthand rotary coding switch to position D.
Note
Each address must be allocated only once
on PROFIBUS-DP. The PROFIBUS address
that you set must match the PROFIBUS
address for this distributor set in the project
configuration software.
If you alter a PROFIBUS address during
operations you will have to disconnect the
power supply and then restart the system to
enable the master to recognise the change.

3.5. Setting the Bluetooth address
Note
Each Bluetooth address can occur only once
with a Piconet. The defined network address
must be identical with a network.
If you alter a Bluetooth address during operations you will have to disconnect the
power supply and then restart the system to
enable the master to recognise the change.
Bluetooth address
The Bluetooth address is used to determine at which
address your SAI distributor will be identified from the
Bluetooth master. The Bluetooth address consists of a
node address and a network address.
Slave address
The slave address defines the location (address) of the
participant within the Piconet. Each slave address can
occur only once within a Piconet. The Bluetooth gateway always uses the node address 0; this cannot be
adjusted.
Network address
The network address defines the Piconet which the SAI
should be connected to. The settings on the SAI and
the Piconet gateway must be identical.
Setting
Set the address for the SAI distributor in the settings
section of the distributor. Use a flat-bladed screwdriver
to adjust the rotary switch.

4.1. PROFIBUS / RS-485
PROFIBUS is a universal, open, digital communication
system providing solutions for a wide spectrum of applications – first and foremost in production and process
automation. PROFIBUS is a suitable solution for fast,
time-critical applications, as well as for complex communications tasks. PROFIBUS communication is anchored in the international standards IEC 61158 and
IEC 61784.61158.
The criteria for its use and planning are defined in the
openly accessible guidelines available from the
PROFIBUS User’s Organisation (PUO). These guidelines fulfil the demands on the part of the users for
multi-vendor and open solutions. That guarantees the
communication between devices of differing manufactures – without having to make prior adjustments.
Additional information is available under
www.profibus.com.
Select the bus cable as cable type A in accordance with
IEC 61158. The PROFIBUS connection is made via a
5-pole M12 male connector (Bus IN) and a 5-pole M12
female connector (Bus OUT). Both connections are Bcoded. Use the "Bus In" connection to feed in signals
and "Bus Out" to route these forward.
In the SAI, male and female connectors are conductively connected. That enables the PROFIBUS to be
routed from SAI to SAI without the need for spur lines.
Note
It is possible to connect the SAI distributors
by means of a spur line for low transmission
rates up to 1500 Kbit/s. The total length of
the spur line must not exceed 6.6 meters.
The spur lines should be kept as short as
possible. Avoid the use of spur lines for baud
rates greater than 1500 Kbit/s.

PROFIBUS addressing
Two rotary switches in the address section of the SAI
are used to make the necessary bus address settings.
The setting is made in hexadecimal code from 00H to
7EH which corresponds to the decimal values from 0 to
126 (see also Appendix C: Converting decimal to hexadecimal, page 82).
Note
It is only possible to set the bus address in the address
section of the SAI. Any alterations made to the bus
address during operations will be recognised and
adopted following the next reset (turning off the power
supply).
The factory-set default bus address on the SAI is 03.
A table is available in the Appendix C to aid
conversion of decimal to hexadecimal addresses.

4AI2AO2DIO
The SAI distributor Active Universal has the functions of
a decentralized I/O system. Each distributor is equipped
with module-specific actuator/sensor functions and a
wireless interface. The module combines the complete
electronics in a water- and dust-proof protected housing.
This enables it to be used in harsh environments.
The SAI-AU M12 BT 4AI2AO2DIO module is used for
connecting four inputs with four M12 connectors; where
two each can be used as outputs.

GSD files (device database files)
GSD files are the electronic data sheets of a device that
provide a PROFIBUS master with straightforward information about the characteristics of the PROFIBUS
DP field device.
The files are provided with the file extension gsd.
The information in these files includes:
•
The supported transmission rates
•
The length of the input and output data to be exchanged
•
The meaning of the diagnostics parameters and
the application parameters
•
The field device type
•
The supported services

5.4. Adding a BT-GW in the hardware configurator
The hardware configuration with a PROFIBUS DPenabled central processing unit (CPU 315-2 DP) has
been launched and a PROFIBUS DP master system
has been defined for this CPU.
You can now add individual devices to the PROFIBUS
DP master system. A pop-up window opens in which
the PROFIBUS address can be assigned. You can set
parameters on the Parameter tabbed page.
Note
Assign each PROFIBUS address only once.

Bluetooth SAI Manual
The gateway which has been inserted now has slots
available for modules. Up to seven modules can be
added to these slots. A maximum of six devices can be
connected with Bluetooth. The seventh device or the
first device depicts 12 digital gateway inputs (digital
input: DI).
Note
According to the definition, the Gateway IOs
must occupy the first slot. No "holes" are
allowed in the slot list. The SAIs must be
listed in the proper order according to their
identifiers (node numbers).
On PROFIBUS, these 12 DIs are connected via a 16-DI
identifier, since only a byte-by-byte assignment is possible.
An excerpt from a gateway is shown in the figure below.
In this example, all available module types are listed
once.
Figure 42: The gateway slot list
These modules are stored in the GSD file. They are
assigned the application parameters in this file. There
are a total of four modules in the selection list: the
Gateway-IOs 12DI, a SAI 16DI, a SAI 16DI/8DO and a
SAI 4AI/2AO/4DI.
Note
The Universal Module is a Step7 attachment
and cannot be deleted.

5.5. Assigning the input and output addresses
Each PROFIBUS DP device is already automatically
assigned an address, with which data is exchanged
with the PLC programme.
You can accept or alter these addresses. The quickest
method is to double-click the address bar of the selected device. Then it is possible to select the starting
address.

Activates the DESINA function
Bits 0 to 7 set the DESINA diagnostics of the connections 1 to 8. The DESINA diagnostics functionality is
activated if the corresponding bit is set to 1. If the
DESINA diagnostic functionality is activated, the connection at pin 4 acts as a DESINA diagnostics input.
The connection at pin 2 is then the switch input to be
monitored.
Defines how the outputs react when there is a bus
malfunction.
The entries for Bit 0 to Bit 7 determine for each output if
it enters a safe status or if it retains the last status. If
this bit is set to 1, the output retains the last status that
prevailed before the bus error occurred. The safe status
is defined in byte 5

Configuration of the analogue inputs
Configuration of the analogue outputs
The four analogue inputs are set with two bits respectively.
The first bit defines the type of measurement as voltage
or current measurement; the second bit sets the measurement range in accordance with the selected measurement.
The type of signals of the two analogue outputs (as
current or voltage output) is determined by the selection
of the connection pin and the configuration. The measurement range is configured in accordance with the
selected output type.

Manufacturer diagnostics information
The manufacturer’s diagnostics information can be
composed of one or more bytes. The manufacturer
determines the amount and their content.
For SAI modules, these include various diagnostic
information depending on the type of module; a part of
this information has to be activated by parameterisation.
An overview of the diagnostic bytes is given below;
these bytes are counted after the standard diagnostics
information byte 6.
The gateway is structured modularly with up to seven
modules. Seven universal modules are established in
the diagnostics data so that each module can be added
to each gateway position.

6.3. Evaluating diagnostic data in Step7
Whereas the data for inputs and outputs can be exchanged and processed directly in Step7 with
PROFIBUS via the input and output image, diagnostic
data must be read into the application programme with
an SFC.
Diagnostics data (slave diagnostics) of a DP slave is
read with the SFC 13 "DPNRM_DG".
Figure 48: Diagnostics function block
Input variables:
REQ = 1:
Request to read
LADDR:
Planned diagnostics address of the DP slave; this can be read in the hardware configurator.
Note: The address must be entered in hexadecimal, for example, the diagnostic
address 1022 (3FEH) means: LADDR: = W#16#3FE
Output variables:
RET_VAL
RET_VAL contains the length of the actual transmitted data.
If an error occurs when the function is being processed, the return value contains an
error code.
RECORD
Target range for the read diagnostic data.
The minimum length of the data record to be read or the target range is 6.
BUSY = 1
The read operation has not been completed
Table 53: Diagnostics function block
In the example above, 10 bytes following the flag byte M 120.0 are reserved as target range of the diagnostics data for
an SAI-AU M12 PB 16DI. These are divided up as follows:

Accuracy
Bit accuracy is a measure of the exactness of digital
measurement and calculation operations. With an accuracy of 8 bit, for example, 1 byte corresponds to an accuracy of 1/(2^8) = 1/256 or 0.390625% steps. This is particularly important when converting from an analogue
signal to a digital value if the measurement value of a
sensor (temperature, pressure or similar) is to undergo
further digital processing.
This is an image file or graphic consisting of pixels; with
black and white information. Each bit corresponds to an
information unit and can consequently code a pixel. For
display purposes in the hardware configurator, bitmap
files in DIB format with 70 x 40 pixels are recommended.

possible to adjust rotational speeds. In particular for
three-phase motors, frequency converters are an economic form of control.
Diagnostic telegrams indicate the status of the
PROFIBUS-DP slave. A diagnostic telegram is composed
of six bytes of standard diagnostics information as well as
the manufacturer’s diagnostics information. The number
of bytes required for the manufacturer’s diagnostics varies from module to module.
Diagnostics data
Diagnostics data is transmitted in a diagnostics telegram.
This information is differentiated between standard diagnostics information (6 bytes) and vendor diagnostics information, the length of which depends on the vendor.

I/O section
Jumpers are used to configure electronic sub-assemblies
or set operating parameters that are carried out either
rarely or only once during initial commissioning procedures.
The jumper is usually made of a small metal plate and a
plastic housing. It is plugged into two pins which results in
an electrical contact being created via the metal plates.
Generally, that results in the function of the hardware component being activated, deactivated or configured.

Voltage with which the device is supplied. The power
supply in automation engineering is usually 18 to 24 VDC.
PROFIBUS
(PROcess FIeld BUS) is a part of the international standards IEC 61158 and IEC 61784. Physically, PROFIBUS
is either an electrical network based on a shielded, two-
Weidmüller t
93
conductor cable or an optical network based on a fibre
optics cable.
PROFIBUS guidelines
Vendor-independent compatibility is guaranteed by technical guidelines to ensure implementation of PROFIBUS
technology. The technical guidelines are published and
distributed centrally by the PROFIBUS User Organisation
(PUO) to underline the fact that these are effectively a
standard. Diverse PROFIBUS guidelines are available,
for example: the "Optical transfer technology for
PROFIBUS".
PROFIBUS slave
PROFIBUS slaves exchange data cyclically with a
PROFIBUS master. In addition, parameterization, configuration and, in the case of a malfunction, diagnostic
data is transmitted. Typical PROFIBUS slaves include
connection terminals, repeaters, gateways, communication terminals, valve blocks and others.
PROFIBUS User Organisation
More than 260 vendors and users of the standardised
communication system PROFIBUS have come together
in the registered association PROFIBUS User Organisation (PUO) to jointly support further technical improvements and establish the use of the technology internationally. The PROFIBUS User Organisation is a registered association. Membership is open to any company or
research facility anywhere in the world.
PROFIBUS-DP
This is a special application for automating factory production. DP = Decentralised Periphery
PROFIBUS-DP address
With the PROFIBUS address you determine at which
address your SAI distributor will be identified on
PROFIBUS-DP.
PROFIBUS-FMS
This is utilised for the universal, object-oriented, cyclic
and acyclic exchange of data at a medium speed. FMS is
particularly suitable for exchanging data between intelligent slaves such as PCs and PLCs. PROFIBUS-DP and
PROFIBUS-PA are special variants.
FMS = Fieldbus Message Specification
PROFIBUS-Master
zation of PROFIBUS slaves by means of software; it is
mainly used to set the PROFIBUS address. As well as
exchanging data with the slave, the Class 1 master supplies the PROFIBUS slave with configuration and parameter data.
PROFIBUS-PA
This is used to control field devices by means of a process control system in the processing industry. This variant
of PROFIBUS is used in hazardous areas (Ex-Zone 0 &
1). Low currents only are used so that no sparks flashover in the case of a malfunction; it uses a slower data
transmission rate.
PA= Process Automation
Protective earth
Protective earth conductors are often used in electrical
equipment and cable lines. This is also known as the protective lead, earth, earth connection or PE (protective
earth).
The task of the protective earth conductor in electrical
systems is to protect human beings from dangerous
touch voltages as well as to protect the system from
damage. The PE conductor is fitted in such a manner that
there is an electrical connection between the outer metal
housing of the electrical equipment (for example lamps,
fridges, motors).
Should a fault occur and the electrical supply voltage
comes into contact with the exterior of a piece of electrical
equipment, the short-circuit to ground via the PE conductor should ensure that the voltage between the housing of
the respective electrical equipment and the ground (with
which humans and animals are generally in contact) is
reduced to a harmless level.
At the same time, the high short-circuit currents trip the
fuse. That ensures that the electrical equipment with the
fault is disconnected extremely quickly from the supply
voltage.
German regulations stipulate that the PE conductor must
be identifiable by the colour combination green/yellow.
Repeater
Repeaters are necessary in order to create a CAN network with more than 32 stations or establish a larger network extension. The repeater represents the beginning of
a new segment in which the maximum number of stations
can be used or the maximum extension is defined.
Rotary coding switch
PROFIBUS-DP differentiates between Class 1 and Class
2 masters. The Class 2 master is utilised for parameteri-

Slave
RS-485
As a so-called differential voltage interface, the RS-485
interface operates with +5V (high) and 0V (low) by which
the non-inverted signal is transmitted via one wire and the
inverted (or negative) signal via the other wire. As distortions have the same effect on both signals, the difference
between both signals remains (virtually) the same and
can be used for evaluation purposes.
Please see PROFIBUS slave.
Temperature coefficient
The temperature coefficient is a relative change to a
physical variable resulting from a change in temperature
of 1 K (Kelvin).
Torx screwdriver
An RS-485 connection constitutes a serial data transmission, which means the bits are transmitted one after the
other on a line.
Torx is an improvement to the cross-head screw and
hexagon-socket (Allen) as a tool receiving socket, for
example in counter-sunk screws.
SAI
The profile is similar to a six-pointed star with rounded off
points and corners – more or less a wave form. The company Camcar belongs to the Textron Group and is the
inventor and patent holder. In the meantime, the Torx
patent has run out and the hexalobular internal drive feature has been incorporated in international standards.
The acronym SAI stands for Sensor – Actuator – Interface. It is a compact-designed distributor or collector of
signal lines.
SAI distributor
Please see SAI.
T-piece
Sampling period
A t-piece is used to provide uninterrupted feed of the
supply voltage and the Fieldbus.
The sampling period determines in which time interval an
analogue input is converted. The sampling period for the
SAI-AU AI/AO/DI can be set between 5 ms and 250 ms.
Segment
The PROFIBUS network consists of one or more segments. The maximum extension of a segment depends
on the baud rate being used. Up to 32 PROFIBUS stations can be connected in each segment.
