POSITIONING MODULE REPLACEMENT

7.2.4 Buffer memory address comparison

Sequence programs need to be changed because the buffer memory address assignment differs.
For details of the buffer memory areas and sequence programs, refer to the MELSEC-L LD75P/LD75D
Positioning Module User's Manual.
area shows the differences between the A1SD75P-S3 and LD75P/D.
When the built-in I/O functions of the LCPU are used, the special register is used. For details, refer to
the MELSEC-L CPU Module User's Manual (Built-in I/O Function).
