Specify the station number of the PLC CPU to which data is
written.
See Section 4.2.2 for the allowable specification range.
Processing code
• Specify 4.
Specify the block number of the extension file registers.
• 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 by
writing 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 memory cassette
mounted on the PLC CPU.
Specify the device number of the extension file registers.
The maximum value that can be specified for the device
number is the value set in the parameters of the PLC CPU.
Specify the number of device points to be written, including
the device specified in %(3).
The allowable specification range is from 1 to 64 points.
