• Specify the extension file registers to which data is to be written along with the data
itself using integer arrays for the number of points to be written in <storage area for
data to be written>.
When specifying the nth device point

For example, when the number of points to be written is 2 points:
The specification for
the first point is
The specification for
the second point is
Specify the block number of the extension file register device.
• If 0 is specified for the block number, data is written to the
file registers of the PLC CPU.
(This is the same processing as writing to R
device memory.)
• If a number greater than 0 is specified for the block number,
data is written to the extension file registers.
• The maximum value that can be specified for the block
number varies depending on the PLC CPU's memory.
Specify the device number of the extension file registers (R).
The maximum value that can be specified for the device
number is the value set in the parameters of the PLC CPU.
Specify the data to be written to the device number.
See Section • • for how to specify the data to be written.
