3.2 Setting the Switches
The DN611 has DIP switches on the front panel and rotary switches on the bottom.
3.2.1
DIP switches for operation mode/communication rate setting
Figure 3-2 DIP Switches for Operation Mode and Communication Rate Setting
(*1)Busoff: Individual DeviceNet nodes check one another for transmission line errors. If
the local node is judged to be the cause of frequent transmission line errors, it is
disconnected from the transmission line. This state is called busoff.

BUSOFF
To specify an operation mode when the DN611 falls into a busoff state (*1).
ON: Once it is in a busoff state, the DN611 initializes the internal network
controller to be in standby mode. After remedying the cause of the busoff,
resume transmission with an instruction from the S controller.
OFF: One it is in a busoff state, the DN611 initializes the internal network
controller and resumes transmission. (Default).
