1-4-2 Master Word Allocation
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.
The first word of the Master’s SYSMAC BUS area varies with the model as
seen in the following table.
