2 Safety instructions
2.1 General
These instructions are part of the device� They contain information and illustrations
about the correct handling of the device and must be read before installation or
use�
Observe the operating instructions� Non-observance of the instructions, operation
which is not in accordance with use as prescribed below, wrong installation or
incorrect handling can seriously affect the safety of operators and machinery�
2.2 Target group
These instructions are intended for authorised persons according to the EMC and
low-voltage directives� The device must only be installed, connected and put into
operation by a qualified electrician�
2.3 Electrical connection
Disconnect the device externally before handling it� If necessary, also disconnect
any independently supplied output load circuits�
If the device is not supplied by the mobile on-board system (12/24 V battery
operation), it must be ensured that the external voltage is generated and supplied
according to the criteria for safety extra-low voltage (SELV) as this voltage is
supplied without further measures to the connected controller, the sensors and the
actuators�
The wiring of all signals in connection with the SELV circuit of the device must also
comply with the SELV criteria (safety extra-low voltage, safe electrical isolation
from other electric circuits)�
If the supplied SELV voltage is externally grounded (SELV becomes PELV), the
responsibility lies with the user and the respective national installation regulations
must be complied with� All statements in this document refer to the device the
SELV voltage of which is not grounded�
The connection terminals may only be supplied with the signals indicated in the
technical data and/or on the device label and only the approved accessories of ifm
electronic may be connected�
2.4 Housing temperature
According to the technical specifications below the device can be operated in
a wide ambient temperature range� Because of the additional internal heating
the housing walls can have high perceptible temperatures when touched in hot
environments�

SmartModule CR2520

2.5 Tampering with the device
In case of malfunctions or uncertainties please contact the manufacturer�
Tampering with the device can seriously affect the safety of operators and
machinery� It is not permitted and leads to the exclusion of any liability and
warranty claims�
2.6 Electromagnetic compatibility
This is a class A product� It can cause radio interference in domestic areas� In this
case the operator is requested to take appropriate measures�
2.7 Electrical welding on vehicles and plants
Welding work on the chassis frame must only be carried out by qualified persons�
Remove and cover the plus and minus terminals of the batteries�
Disconnect all contacts of the device from the on-board system prior to welding on
the vehicle or plant� Connect the earth terminal of the welding device directly to the
part to be welded�
Do not touch the device or electric cables with the welding electrode or the earth
terminal of the welding device�
Protect the device against weld slag�

3 Functions and features
The CR2520 I/O module enables decentralised evaluation of sensor signals and
decentralised triggering of actuators and DC motors�
●The module supports binary/analogue inputs/outputs and is therefore classified
in the device class "I/O module" to CiA DS 401�
●As regards the input/output functions, the module can be configured and it
supports the following functions:
– analogue inputs (0���10V/32V; 0���20mA, ratiometric, binary)
– binary inputs
– binary outputs
– half bridges (push-pull outputs)
– full bridges with/without PWM
●There are 1 server SDO and 8 default PDOs according to CiA DS 401�
The PDO mapping cannot be changed (static PDO mapping)�
The default identifiers are assigned according to the "predefined connection
set"�
●The COB IDs of the PDOs as well as the transmission type (synch/asynch) of
the individual PDOs can be configured�
●The module expects a sync object�
The CAN identifier of the sync object can be configured�
●The module supports "node guarding" and "heartbeat"�
The "guard time", the "life time factor" and the "heartbeat time" can be
configured�
●The module generates an emergency object� The COB ID of the EMCY object
can be configured�
●The module stores the last 4 errors�
The error code of the corresponding emergency object is stored�
●The module supports a reset function, i�e� assignment of the parameters to the
factory default values* upon request�
WARNING
The device is not approved for safety-related tasks in the field of operator
protection�

6 Set-up
6.1 PLC configuration in CODESYS 2.3
Parameter setting of the device functions and of the CAN interface is directly done
from the application programmed with CODESYS 2�3� To do so, the "Electronic
Data Sheet" (EDS) is integrated via the CODESYS PLC configuration�
CODESYS dialogue "PLC configuration" (example)
For a description of the setting and application of the "PLC configuration“ dialogue
see the CODESY manual and the CODESYS online help�

SmartModule CR2520

as follows in the main menu:
►Click on [Tools] / [Device Repository]�
►Select [Fieldbuses] / [CiA CANopen] / [CiA Remote Device] and click on
[Install]�
►Select EDS file and click on [Open]�
> In CODESYS 3�5 the devices are integrated as CiA remote devices in the
device tree under a [CANopen_Manager] element�
The CANopen communication is configured via the CODESYS configuration
editor�
6.2.1 Heartbeat conguration
The function [Reset Node] must be activated on the tab [General] so that the
device applies the parameters set for heartbeat monitoring of the CANopen
Manager�

6.2.2 SyncMonitoring
To activate the device-internal monitoring of the Sync cycle, the monitoring time
has to be written into the object directory entry 0x1006� This is possible by
supplementing the SDO list in the CANopen configurator or during the operating
time via the function block COP_SDOwrite�
The monitoring time is indicated in microseconds [μs].
6.3 Electronic Data Sheet
The EDS contains the description of all parameters and I/O data of the device in a
format defined by CANopen� The EDS files are provided for all CANopen slaves by
ifm electronic�

8 Parameter overview
8.1 General
Automatic saving of the communication and device parameters can be activated
or deactivated by means of the "save parameter" entry (see object directory, index
1010)�
When the value 0x02 is entered into SIdx 01, all parameters are automatically
saved if changes were made�
With the value 0x00 there is no automatic saving, i�e� changed parameters will only
be valid until the device is switched off or until the next reset is made�
With the function "restore" (see object directory , index 1011) the factory default
values can be restored (except for the baud rate and the node ID)� They become
valid with the next power on�

*) The entries 20F0/20F1 and 20F2/20F3 must always contain identical values�
The new entries are valid after a reset (switching the module off/on)� Values
outside the permissible ranges will be rejected�
