3.1.7 Correspondence between X-SEL I/O port number and PLC address
PLC sets the X-SEL CC-Link board as a remote device.
The number of occupied stations of the remote device varies according to the setting of the number of I/O
points on the X-SEL side.
The table below indicates the correspondence between the I/O port number and PLC address according to
the settings of I/O parameters No. 14 and No. 15. (The following is a case where the I/O parameters No. 2
and No. 3 have standard settings [defaults].)
Note: For the I/O parameters No. 14 and No. 15, set the same points according to the larger number of points.
(1)
When the number of I/O points is set to 96 or less:
Configured as one remote device. (One station occupied)
