(2) Setting method
In the Head Module window of MT Developer2, set the total number of the input/output (X/Y) points of the
modules connected to the head module in 16-point units.
To match the settings with those in the figure on the previous page, set "RX Link Device" and "RY Link Device" to
"0000" to "003F".
• To set an empty slot in the head module or to change a start I/O number, modify the data in the I/O Assignment
setting of the head module with GX Works2.
• If the number of points is going to be increased for a system extension or other reasons, set a large number of
"RX Link Device" and "RY Link Device" in the Head Module window of MT Developer2. Doing so will avoid
changing the parameter of the Motion controller at the system extension. However, increasing the number of the
points lengthens the processing time.
