Control Station Return Setting - Mitsubishi Electric SW0DNC-MNETH-B User Manual

7 PARAMETER SETTINGS

7.5 Control Station Return Setting

7 - 12
This parameter is used to designate the type of station used by the control station
when returning to the network in the control station return control.
Select this parameter to make the control station return as a normal station without
stopping the baton pass in the system in operation.
The control station return setting is required only for the control station.
(1) When "Return as control station" is selected (default)
The baton pass (cyclic transmission, transient transmission, etc.) temporarily
stops because the control station sends the parameters to the normal stations
and returns to the network.
(2) When "Return as normal station" is selected
The control station returns to the network as a normal station, without stopping
the baton pass in the network.
REMARK
• When "Return as control station" is selected, the network stop time becomes
longer because the baton pass is stopped, but the common parameters can easily
be changed only by resetting the Board of the control station.
• If "Return as normal station" is selected, the network does not stop because the
control station returns to the network without stopping the baton pass.
However, it is necessary to reset the CPUs of all the stations after changing the
common parameters of the control station while the network is in operation.
If only the board resetting is performed, the MELSECNET/H board (Control
station) detects the parameter mismatch error and disconnects it.
