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.
