(a) Modules that can load input (X) data
Data in the input (X) can be loaded from the following modules mounted on the main base unit or extension
base unit.
*1 When input (X) of the QX48Y57 (I/O combined module) is targeted, data in Xn8 to XnF (output part) are loaded as all
points off.
*2 When input (X) of an output module is targeted, data are loaded as all points off.
(b) Modules that cannot load input (X) data
Input data of empty slots and MELSECNET/H or CC-Link network remote stations controlled by other CPU
modules cannot be loaded. To use the input data (on/off data) in a CPU module other than the control CPU,
perform auto refresh using the CPU shared memory. ( Page 118, Section 6.1)
If the input data loaded from other CPU modules are forcibly turned on/off in the host CPU module, the data will be set into
the specified forced on/off status. ( User's Manual (Function Explanation, Program Fundamentals) for the CPU module
used)
(2) When the "All CPUs Can Read All Inputs" checkbox is not checked
The on/off data of input modules and intelligent function modules controlled by other CPU modules cannot be
loaded. Data in the input (X) remain at off.
