7.18.13 Reading Data from Designated File (SP.FREAD)
(3) Be sure to use word units to designate the number of request read data ( +2), file position
( +4 and +5), and read data device size ( ).
The following shows how the individual device data is read in binary data reading operation.
(4) When reading binary data
(a) If the extension of the target file is omitted, ".BIN" is used as an extension.
(b) When the designated file does not exist, an error occurs.
(c) If the position specified is greater than the existing file size:
• The High Performance model QCPU of which the first 5 digits of the serial number
are "01111" or lower results in an error.
• The High Performance model QCPU/Process CPU/Redundant CPU/Universal
model QCPU of which the first 5 digits of the serial number are '01112' or higher will
perform reading at point 0 and will be completed normally.
(5) When reading data after CSV format conversion
(a) The elements in CSV format file (cells for EXCEL) are read by each row. The numerical
value and character strings are converted into binary data and stored in the device.
(b) If the extension is omitted, ".CSV" is used as an extension.
(c) When the designated file does not exist, an error occurs.
(d) The elements designated by the number of request read data ( +2) are read from the
beginning of the file.
When the last data of the file is reached before the specified number of data are read:
• The High Performance model QCPU of which the first 5 digits of the serial number
are "01111" or lower results in an error.
• The High Performance model QCPU/Process CPU/Redundant CPU/Universal
model QCPU whose the first 5 digits of the serial number are '01112' or higher reads
the data up to the point where the reading is possible.
