21.6 Module Access Device
This device directly accesses from the CPU module to the buffer memory of the intelligent function module mounted on the
main base unit and extension base unit.
Specify this device with 'Un\Gn'. (Example: U5\G11)
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.
Specified item Value to be specified
Un Start I/O number of intelligent function modules Upper two digits when a start I/O number is described in three digits
(00H to FFH)
Example: 1F stands for X/Y1F0
Gn Buffer memory address 0 to 268435455 (decimal)
