Caution
1. Keep the DIP switch OSEN in the OFF position. Setting it to ON can cause trouble or mal-
function.
2. Set all the nodes connected to the network to the same communication rate.
Different communication rates among the nodes will cause a slave device error or DN611
error, and disable to start communication. For slave device communication rate setting, refer
to the manuals concerned.
Do not change the communication rate while the S controller power is on.
3. Otherwise, a communication rate setting error will occur. Particularly, do not change the
communication rate while transmission to a slave device is under way.
To reset, either issue a reset request or turn power back on again after correctly setting the
DIP switches.
To reset, either issue a reset request or turn power back on again after correctly setting the
DIP switches.
Usage Recommendations
1. If the DIP switch BUSOFF is set to OFF, transmission will restart automatically when a busoff
occurs. Unless the cause of the DN611's busoff (cause of communication error) is remedied,
however, a busoff may occur again.
2. If both DIP switches DR0 and DR1 are set to ON, a communication rate setting error will
occur when the S controller is switched on.
• The LED MS blinks red.
• The 7-segment LED displays F7 and the local node address alternately
To reset, either issue a reset request or turn power back on again after correctly setting the
DIP switches.
Usage Recommendations
1. Use a small flat-tip screwdriver for changing the DIP switch values.
