9.3.2 Partition setting (FIX/FREE)
For most circumstances,
FREE
is the appropriate partition setting. However, you will need to set
FIX
if the
PI/O modules connected by remote I/O have more than 2,048 I/O points in total. The
FIX
setting allows a
maximum of 2,048 input I/O points, and a maximum of 2,048 output I/O points.
●
The FREE setting removes the limitation that designates each I/O slot on the CPU mount base or PI/O mount
base as either an input or output slot. Each slot is assigned an I/O number for input purposes and another for
output purposes (X0 AAA and Y0 AAA ). This allows you to specify the I/O number that is appropriate for the
PI/O module you are installing.
●
The FIX setting reserves I/O slots 1 to 3 on the CPU mount base for input modules, and slots 4 to 7 for output
modules. Similarly, the I/O slots on the left half of the PI/O mount base are reserved for input modules, and
those on the right half are reserved for output modules. I/O numbers are assigned to the input slots in the
format X0 AAA , and to output slots in the format Y0 AAA .
