"Node Guarding" is the oldest protocol which monitor the presence of the Can-Open slaves in the Can-Open fieldbus.
This Protocol is supported by all all our Can-Open masters. (Quantum/Premium/M340/M580).
The network manager polls each device (slave) to check its heath.
The "Heartbeat" is the more recent protocol which monitor the presence of the Can-Open slaves in the Can-Open fieldbus.
This Protocol is supported only by our recent Can-Open masters. (M340/M580).
This protocol is similar to a client server protocol:
Each device provides a life sign periodically.
The benefits is that it required less bus load than node guarding
