Error Processing and Recovery Method
Layer 2 modes: The configuration must not be changed when the module is set to ONLINE, before changing the configu-
ration set Yn0 to OFF (configuration mode) and wait until Xn0 is OFF (module OFFLINE/INIT). The affected configurations
buffer memories are Un\G10000 to Un\G10293, Un\G6000 to Un\G6167 and Un\G8400 to Un\G8402.
Any CANopen€ node will check all CAN messages on the bus for errors. Depending on the error state the action that the
node will take is different:
In error active state:
The node will actively mark the frame as invalid.
In error passive state:
The node will not actively mark the frame as invalid to avoid bus disturbance if the node itself has an H/W problem.
