Setting method
Set the control station return control under "Operation after Reconnection" in "Required Settings". (Page 59 Operation
after Reconnection)
Precautions
• Baton pass stops when "Return as Control Station" is set. The common parameters can be changed only by the CPU reset
operation of the control station although the network stop time is prolonged. Transient transmission that is executed when
baton pass stops may be completed with an error. In this case, execute the transmission again.
• Baton pass is returned without stopping if "Return as Normal Station" is set. Since the network connection does not stop,
perform CPU reset operation for all stations after changing the common parameters of the control station during network
connection. When CPU reset operation is performed only for the control station, an error occurs and the control station is
disconnected with an error. (Error code: F826H)
