In case of malfunctions or uncertainties please contact the manufacturer� Tamper-
ing with the unit can lead to considerable risks for the safety of persons and plant�
It is not permitted and leads to the exclusion of any liability and warranty claims�
3 Function and features
The CR2031 I/O module enables decentralised triggering of actuators and propor-
tional valves� The coil current can be monitored and controlled via the integrated
current measurement�
4 Function
● The module supports binary/analogue outputs and is therefore classified in the
device profile "I/O module" to CiA DS 401�
● As regards the output functions, the module can be configured and it supports
the following functions:
– binary outputs with/without current detection; up to 4 A
– PWM outputs with/without current detection; up to 4 A
– current-controlled PWM outputs, up to 4 A
– selectable current measuring range 0���1 A or 0���4 A�
● There are 1 server SDO and the 3 default PDOs 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 synch object� The CAN identifier of the synch 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� When there are no
heartbeat or node guarding signals, the outputs are automatically switched off
by the operating system�
● The module generates an emergency object� The COB ID of the EMCY object
can be configured�
● The module stores the last error�
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�
● The CR2031 I/O module ist not approved for safety-relevant tasks in the field of
safety of persons�
