• When data is added by the High Performance model QCPU/Process CPU/Redundant CPU/Universal model QCPU/LCPU
of which the first five digits of the serial number are 01112 or higher:
*1 Unless the "No. of request write data" is set to an integral multiple of "No. of columns designation", the column numbers will be random.
*2 Since the last data is always followed by the line feed code, addition normally starts at the beginning of the new row in the addition
mode.
*3 If, in the addition mode, "column designation" is changed from that in the previous writing, the column numbers are shifted.
• Do not execute the SP.FWRITE instruction in an interrupt program. (If execute it, the operation is not guaranteed.)
[Specify the file to which data will be written.] (If a file exists, delete it and create a new file again.)
[In the addition mode, make addition from the end of the file.]
