Heartbeat:
Working with Heartbeats is an alternative guarding mechanism: In contrast to the
Nodeguarding functionality it can be executed by Master- and Slave-Modules. Usually
the master will be configured to send heartbeats to the slaves.
Enable heartbeat generation: If this option is activated, the master will send
heartbeats according to the interval defined in "Heartbeat time". If new slaves with
heartbeat functionality are added, their heartbeat behaviour will automatically be
enabled and configured appropriately, that is, the node-ID is identical to the setting in
the manager configuration, whereas the heartbeat interval gets multiplied by the
factor 1,2. If heartbeat generation of the CANopen manager is not enabled, then
nodeguarding is enabled instead for the slave (with life time factor 10 and a guard
time of 100ms). Notice that the CANopen (slave) devices might be configured as
heartbeat producer.
Node ID: Unique identifier of the heartbeat producer (1 - 127) on the bus.
Heartbeat time (ms): Interval of heartbeats in milliseconds.
When multiple devices are added to the CANopen manager, you may get error
messages reporting multiple assigned node IDs or wrong COB-IDs stemming from the
device description files. The button Check and fix configuration allows to resolve these
conflicts within the opening dialog:
