3.1 What is IndraControl S20?
IndraControl S20 is a modular I/O system for the control cabinet. Open to all Ether-
net-based communication protocols, IndraControl S20 offers maximum flexibility.
In addition, IndraControl S20 is fast as regards response times and installation, ro-
bust in terms of its design and mechanics, and at the same time very easy to op-
erate.
It is used for the transmission of process signals to a higher-level controller. Vari-
ous networks are supported.
3.2 Features
IndraControl S20 is fast
IndraControl S20 features shortest response times and fast synchronous signal
processing. This reduces cycle times and helps to increase the machine output
and productivity. In addition, the control quality and as a result the product quality
increases thanks to the fast signal processing feature.
IndraControl S20 is as fast as parallel cabling, so the speed for data transmission
is determined by the higher-level network.
• Synchronous to the higher-level network (depends on the bus coupler)
• Local bus cycle time in the µs range
• Fast I/O update times
• Fast and efficient station set-up
IndraControl S20 is robust
IndraControl S20 is particularly robust with regard to its design and mechanics.
The high electromagnetic compatibility, noise immunity, and low emissions ensure
problem-free use in the industrial environment and beyond.

The IndraControl S20 product group
10/122 Bosch Rexroth AG DOK-CONTRL-S20*SYS*INS-AP02-EN-P
IndraControl S20 System and Installation
IndraControl S20 is easy
Extremely user-friendly. Thanks to the Push-in connection technology, you can
wire efficiently without tools – solid conductors or conductors with ferrules can be
inserted directly into the terminal block. The color coding of the contact points en-
ables fast and intuitive wiring – this saves installation time and therefore also costs.
In addition, intelligent marking systems from Bosch Rexroth simplify the individual
I/O system marking.
Clear wiring: the design supports cabling from above and below. Module replace-
ment is particularly fast with existing wiring.
Other properties
• High channel density
• Voltage ranges: 24 V DC (protective extra-low voltage) and
up to 220 V DC/230 V AC (low voltage)
• Transmission speed in the local bus: 100 Mbps
• Communication to the higher-level system via an Ethernet-based protocol
(e.g., PROFINET, Sercos, EtherCAT®, Modbus/TCP, EtherNet/IP™)
• Very good diagnostic properties for the IndraControl S20 system and appli-
cation

3.3 Structure of an IndraControl S20 station
An IndraControl S20 station consists of individual modules that are snapped onto
a DIN rail.
A controller or a bus coupler forms the head of the station. I/O modules are
mounted next to it.
Bus base modules are used for the connection of the individual modules to one an-
other and to the station head. The bus base modules are snapped onto the DIN rail
side by side and thus form the local bus.

IndraControl S20 System and Installation
Voltage ranges IndraControl S20 modules are available for the protective extra-low voltage
(PELV) and the low voltage range. You can use low-voltage and extra-low voltage
modules directly next to each other within an IndraControl S20 station.
Mounting location The IndraControl S20 modules meet IP20 degree of protection and can be used in
closed control cabinets or in control boxes (terminal boxes) with IP54 degree of
protection according to EN 60529 or higher.
The compact design means that the IndraControl S20 modules can be installed in
standard terminal boxes. Please observe the mounting distances when selecting
the housing (see Chapter “Mounting distances” on page 52).
Mounting Each IndraControl S20 module consists of a bus base module and an electronics
module. Snap the bus base modules onto the DIN rail without the need for tools
and arrange the modules side by side. The local bus is created automatically when
the bus base modules are installed next to one another.
Then, snap the electronics modules onto the DIN rail over the bus base modules.
See Chapter “Mounting and removing modules” on page 37.
Removal Only a standard tool is necessary for removing the electronics module (e.g., a
bladed screwdriver with a blade width of 2.5 mm).
See Chapter “Mounting and removing modules” on page 37.
Bus connection (network) The IndraControl S20 station is integrated in the network using a controller or bus
coupler.
Local bus There is an interface to the local bus on the bottom of the modules. Bus base mod-
ules are used to carry the communications power and the bus signals from the
controller or bus coupler through the IndraControl S20 station. The bus base mod-
ule is supplied as standard with each module.
The maximum number of IndraControl S20 modules within a station is 63. The ac-
tual number of modules within an IndraControl S20 station may be limited by the
supplied logic current, the current consumption of the connected modules, and the
system limits of the controller or bus coupler. See Chapter “Maximum number of
modules” on page 42.

IndraControl S20 System and Installation
Connectors The IndraControl S20 modules have connectors for connecting the power supply
and the I/O. The connectors have spring-cage terminal blocks. Suitable wires can
be connected with Push-in technology (see Chapter “Conductor cross sections
and stripping/insertion lengths” on page 56).
Connecting the supply volt-
age
The communications power for the IndraControl S20 station is supplied at the con-
troller or bus coupler. The voltage for the module’s I/O is supplied separately to
each I/O module (see Chapter “Connecting the power supplies” on page 62).
I/O connection Sensors or actuators are connected with connectors using 1, 2, 3 or 4-wire tech-
nology (see Chapter “Connecting sensors and actuators” on page 66).
Depending on the module, the sensor/actuator cables are connected in one direc-
tion (at the bottom) or in two directions (at the top and at the bottom).
FE connection At the bottom of each module there is at least one FE spring (metal contact) creat-
ing a functional earth ground connection when the module is snapped onto a
grounded DIN rail.
Web-based management By means of the web-based management integrated into the controllers and some
bus couplers, you have the option to display static and dynamic information of the
controller using a standard browser. The status and diagnostic functions can be
displayed on a graphical user interface by means of read access via a device net-
work connection.
In addition, specific controller/bus coupler properties can be configured via web-
based management.
Diagnostics The IndraControl S20 system provides comprehensive diagnostics:
• Remote diagnostics
• Process diagnostics (e.g., cycle time monitoring)
• Communication diagnostics
• Module diagnostics (status of the IndraControl S20 module)
• I/O diagnostics (status of sensors/actuators)
For the diagnostic options of a specific module, please refer to the module-specific
data sheets.
Reset button The reset button provided on the controllers and bus couplers can only be oper-
ated with a pointed object (e.g., a pen) and is therefore protected against acciden-
tal activation.
If the reset button is actuated during operation, the controller or bus coupler is re-
started.
Using the reset button, the controller or bus coupler can also be reset to the default
settings.
3.5 Intended use
IndraControl S20 controllers, bus couplers, and I/O modules should only be used
according to the instructions given in the module-specific documentation and this
application description (see Chapter “Technical data” on page 93). Bosch Rexroth
accepts no liability if the modules are used for anything other than their designated
use.
For more detailed information on the reset button, please refer to the
module-specific documentation.

4.2 Controller
Fig. 4-2 Example: XM21
As the head of an IndraControl S20 station, the modular controller with Ethernet
and IndraControl S20 local bus connection provides the function of a controller.
A class XM2x controller is the ideal controller for medium-sized to complex appli-
cations in which networking options as well as a particularly short processing and
response speed are required.
Optional extension modules increase the integration possibilities.
These modules are installed next to each other on the left side of the
controller. The service-friendly design easily reduces installation and
startup costs.
Please refer to the DOK-CONTRL-XFE**EXTMOD-IT..-EN-P operat-
ing instructions, material number R911345570 for further information.
