The program example for mode switching is shown in Diagram App.27.
(For the I/O signal is X/Y80 to X/Y9F)
POINT
1. Stop all data communication before mode switching. Data communication will
be stopped when mode switching is performed during data communication.
2. Note that station No. setting change and switching to linked operation/
switching from linked operation to independent mode cannot be made.
