(Note 1) For CC-Link, n and n+1 are for input and output bit addresses, and n+8 is for the top
address of data register.
(Note 2) Remote I/O Mode occupies 12 words no matter how many axes are connected.
(Note 3) This is the
area
occupied unconditionally. Therefore, this
area
cannot be used for any
other purpose.
Caution : 1) Remote I/O Mode cannot be used together with other modes.
2) Only Remote I/O Mode can be selected in MEC Mode Type.
3) Only Positioner 3 Mode and Remote I/O Mode can be selected in
MECHATROLINK and CompoNet. (CompoNet occupies 32 bytes no matter of the
number of axes.)
