FX3 allocation mode function

This function operates the buffer memory areas of the analog input module with the same layout as the buffer memory
addresses equivalent to FX3U-4AD.
Operation
In FX3 allocation mode, only allocation of buffer memory area is changed. The following buffer memory area is allocated the
same as FX3U-4AD.
Buffer memory areas
Un\G10 to 13
Un\G26
Un\G27
Un\G30
Un\G61 to 64
Un\G101 to 104
Un\G109
Un\G111 to 114
Un\G119
For buffer memories with different allocations from FX3U-4AD, it can be used by changing the program. For buffer memory in
FX3 allocation mode, refer to the following.
