5 ASSIGNMENT OF I/O NUMBERS
5.7 Examples of I/O Number Assignment
This section shows the examples of the I/O number assignment using GX Developer.
(1) When changing the number of points of an empty slot from 16 to 32
points:
Reserve 32 points to the empty slot (slot No. 3) so that the I/O numbers do not
change when a 32-point input module is mounted in the future. (The empty slot
for slot No. 12 is not changed from 16 points.)
