Intended use
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
and stripping/insertion lengths" on page
The communications power for the IndraControl S20 station is supplied at the con-
age
troller or bus coupler. The voltage for the module's I/O is supplied separately to
each I/O module (see
Sensors or actuators are connected with connectors using 1, 2, 3 or 4-wire tech-
nology (see
Chapter "Connecting sensors and actuators" on page
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).
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.
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.
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.
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.
For more detailed information on the reset button, please refer to the
module-specific documentation.
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
accepts no liability if the modules are used for anything other than their designated
use.
