Functional safety and CANbus integration
The Rugged CAN Keypads feature high reliability
and are designed for functional safety in
accordance with the EN ISO 13849 PLD and ISO
26262 ASIL B standards. Functional safety with
CANopen Safety and ASIL B according to ISO
26262 and PLD according to DIN EN ISO 13849
are available from 2020 onwards. Put simply,
functional safety means that the system monitors
whether the safety-related function is working
properly. This means that whenever a pushbutton
is pressed, the correct signal must be generated.
The functionality must be constantly monitored,
and an easily understandable warning and error
message must be generated. In the simplest case
it’s just information to the operator but in safety
and security-relevant situations, a machine must
automatically go into a safe mode to avoid harm
to people or assets. Thanks to the CAN bus
integration, the devices are intelligently and easily
integrated into a CAN system. The most common
bus protocols in this application field are J1939
and CANopen along with CANopen Safety for
functional safety applications. iVT
