6.5 I/O Number Assignment
6.5.1 I/O number of base unit
The C Controller module assigns I/O numbers at power-on or reset.
Figure 6.14 shows an example of the I/O number assignment when the base unit is set in
Auto mode without I/O assignment.
The above example assumes that the I/O points of the intelligent function module are 32
points.
The number of I/O points changes depending on the intelligent function module.
Check the number of I/O points in the manual of the used intelligent function module
before assignment.
POINT
The C Controller module can control the system even if I/O numbers have not
been assigned on the C Controller setting utility.
