Bus Node Diagnostics

The CANopen fieldbus card FC510x has a comprehensive range of diagnostic options for connected
network nodes.
For each CANopen fieldbus node there is a node state input variable, which signals the status of the current
slave during the runtime and can be linked, for example with the PLC.

TwinCAT is stopped
All configured bus devices are error-free (box state = 0); TwinCAT task
or process is running.
The task whose process data are linked to the card is not running.
All configured bus devices found and error-free (box state = 0)
At least one box state is not zero (e.g. device not found, wrong
configuration, device fault), TwinCAT task is running
At least one box state is not zero (e.g. device not found, wrong
configuration, device fault), TwinCAT task is not running.
TwinCAT is running, CAN controller is Bus OFF. Physical CAN
problem. Possible causes: e.g. missing termination resistor, bus line
too long, wrong baud rate, node address assigned twice, wiring fault,
short circuit.
Restart required
