Notes
• The MAC ID and Baud Rate attributes are not settable via the network (they are set via the
drive’s parameter settings). Attempting a Set service will result in a “Service Not Supported”
error.
• The setting of the BOI attribute is saved in the DeviceNet unit’s internal EEPROM. If the BOI
value is set to TRUE, the DeviceNet interface will attempt to restart the network interface on
the occurrence of a CAN bus-off event. This will continue to be the behavior until the Bus-Off
Counter attribute achieves a value of 255. If a CAN bus-off event occurs after this point, the
unit will not attempt to restart the network interface: it will remain faulted and isolated from the
network until the drive is reset or power cycled.
