Caution
(1) For only QCPU, only the ATA card drive (2) can be set as
Note that when the Flash card is loaded, the SP.FWRITE instruction cannot be used to perform writing.
The SRAM card, standard RAM or standard ROM drive cannot be set.
For only LCPU, only the SD memory card drive (2) can be set as
(2) For CSV setting, the data written are decimal values.
Example
Character "A" (41
Handling range: -32768 to 32767
(3) For binary write, the word-specified file position setting range is 00000000
(4) For the LCPU, this instruction cannot be executed while SM606 (SD memory card forced disable instruction) is ON. Even
if the instruction is attempted to be executed, the command will be ignored.
Function
(1) The designated number of data is written to the designated file.
Set the execution/completion type in the control data to designate whether to write binary data without any conversion or
to convert binary data into CSV format data before writing it.
(For QCPU, writing is only supported for ATA cards. For LCPU, it is only supported for SD memory cards.)
(2) The execution completion bit device (
instruction is detected. The bit device is turned OFF at the execution of the END instruction in the next scan.
Use this bit device as the execution completion flag for the SP.FWRITE instruction.
When this instruction is completed abnormally, the error completion device (
with the processing complete (
SM721 is turned ON during the execution of the instruction.
This instruction cannot be executed while SM721 is ON. (If an attempt is made, no processing is performed.)
