7.6.3 I/O signals comparison to CPU module

An addition or change of a sequence program is required because the I/O signals partly differ between
the modules.
For details of the I/O signals or sequence program, refer to the MELSEC-Q QD73A1 Positioning Module
User's Manual.

Use prohibited
*1 The XY number same as the AD70 can be used for the QD73A1 by setting "Empty 0 point" to the "Unused" area of the
QD73A1 (first half slot: Empty 16 points) in I/O assignment of PLC parameter.
*2 A "Use prohibited" area is reserved for the system use and cannot be used by a user.
If it is turned on/off through a sequence program, the normal operation of the module cannot be guaranteed.
