2 ASSIGNMENT FOR MODULES
2.2 I/O Numbers of Modules
Changing I/O numbers
Upon placing a module on the "Module Configuration" window, the I/O numbers are automatically assigned according to the
number of occupied points of the module. In the following cases, however, change the I/O numbers on a module-by-module
basis:
• To eliminate the need of modification due to an overlap of I/O numbers after the module is changed to a module having a
different number of occupied points
• To reduce the program modifications when using an existing program by assigning modules according to the I/O numbers
that have already been used in the program
I/O numbers can be freely assigned beyond a boundary between the MELSEC iQ-R series and the MELSEC-
Q series, being free from the restriction of assignment orders.
