2) Input(X) loading is performed for the modules shown in Table3.8, which are mounted to the main base unit
or extension base unit(s).

*1: When input(X) loading is performed for QX48Y57 of I/O composite module, input(X) is loaded as all points OFF in Xn8 to
XnF assigned to output part.

*2: When input(X) loading is performed for output module, input(X) is loaded as all points OFF.
3) Input data cannot be loaded from empty slots and remote stations on MELSECNET/H or CC-Link networks
being controlled by the other CPU.
Use auto refresh of CPU shared memory to use the ON/OFF input data for remote stations on
MELSECNET/H or CC-Link in non-controlled CPU.
By enabling "ALL CPUs can real all outpus" setting, input data controlled by other CPUs can be loaded into the host CPU.
In this case, if the forced ON/OFF of external I/O is activated for the input data loaded from other CPUs to the host CPU, the
data will be set into the specified forced ON/OFF status.
For the forced ON/OFF of external I/O, refer to the following manual.
User's Manual (Function Explanation, Program Fundamentals) for the CPU module used
(b) When "Not all CPUs can read all Inputs" has been set
It is not possible to loads ON/OFF data from input modules and intelligent function modules being controlled by
other CPUs (remains at OFF.)
