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.
• 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

however, a busoff may occur again.
• 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
