The heartbeat function can be used for mutual monitoring of the CANopen modules (especially to
detect connection failures). Unlike node guarding/life guarding the heartbeat function does not require
RTR-Frames.
Function:
A module, the so-called heartbeat producer, cyclically transmits a heartbeat message on the CAN-bus
on the node-guarding identifier (see object 100E
h
). One or more heartbeat consumers receive the
message. It has to be received within the heartbeat time stored on the heartbeat consumer, otherwise a
heartbeat event is triggered on the heartbeat-consumer module. A heartbeat event generates a heartbeat
error on the CAN-CBX module.
Each module can act as a heartbeat producer and a heartbeat consumer. The CAN-CBX module can
represent at most one heartbeat consumer per CAN net.
