Specified item
Un Start I/O number of intelligent function modules
Gn Buffer memory address
When reading/writing the buffer memory data using the module access device more than twice within a
program, the processing speed can be increased by conducting read/write operations at a single point of the
program using the FROM/TO instruction.
• When data is written using more than one module access device:
• When data is written at a single point of the program using the TO instruction:
(1) Store data to devices such as the data register (D).
(2) Write data to only one point in the program.
Value to be specified
Upper two digits when a start I/O number is described in three digits
(00H to FFH)
Example: 1F stands for X/Y1F0
