·If a slave station's I/O area is not linked to
the previous slave station's I/O area, this
slave station should be set as a "single
address slave station ."
·If a slave station's I/O area is linked to the
previous slave station's I/O area, you do not
have to set the address this slave station if
"continuous address" is selected (turn OFF

the linked slave stations accordingly.
If you want to disable automatic address changes, select the "single address" mode, even if the
slave station address is in a continuous series with the previous slave station addresses. Then
