*1External Data Register can be used in the CPU of which first 5 digits of serial No. is 09042 or later.

*2To use addresses D0065536 or higher, or addresses W010000 or higher, the Serial Communication unit must meet the following requirements:
- The first 5 digits of the serial number are 09043 or later.
- The function version is B or later.

*3External Link Register can be used in the CPU of which first 5 digits of serial No. is 09042 or later.

*4It is different by the memory card which uses the range of file register.

*5Device for accessing SLMP compatible devices, as well as the intelligent function unit’s buffer memory. The first three digits of the address specifies the intelligent module’s starting I/O number.
