The Master treats the CQM1-LK501 I/O Link Unit as a SYSMAC BUS Remote
I/O Slave Unit. Words are allocated to the SYSMAC BUS area and specified by
the Master in the same way as other SYSMAC BUS Remote I/O Slave Units. All
words to be used in the SYSMAC BUS area are set using the DIP switch of the
CQM1-LK501 I/O Link Unit as shown in the following figure.
