Switch
One Disconnect/Connect Switch is allocated to each slave node address. If
the switch for a slave is turned ON, then remote I/O communications to that
slave will be temporarily stopped (i.e., it is disconnected from the network). A
communications error will occur at the end for any slave has been discon-
nected if the corresponding switch is turned ON during communications.
These switches are used primarily to replace slaves or to reserve a place for a
slave that will be added (when a Unit is registered in the scan list but not yet
connected). A communications error and verification error for the slave that
has been disconnected will not be generated at the master as long as the cor-
responding switch is ON.
Note These switches do not add or remove slaves from the registered scan list.

Remote I/O communications will restart if a user turns OFF a bit that is ON.
More than one of these switches may be turned ON at the same time. If the
switch for a slave that is not using remote I/O communications is turned ON, it
will be ignored.
A Unit that has been disconnected can still perform message communica-
tions.
Turning ON this bit does not effect the communications cycle time (except that
it increases blank time in the communications cycle).
Note All Disconnect/Connect Switches are cleared and return to OFF
when the power is turned OFF. If required, write the ladder program
to turn them back ON when the power is turned ON.
