7.6 Reading/Writing Data Instructions
Description
Specify the execution type.
■00**H: Reading binary data
• 0000H: 16-bit binary data
• 0001H: 32-bit binary data
■01**H: Reading data after converted to CSV format
• 0100H: Decimal (16-bit data)
• 0110H: Decimal (32-bit data)
• 0120H: Hexadecimal (16-bit data)
• 0121H: Hexadecimal (32-bit data)
• 0130H: String (ASCII data)
• 0140H: Floating point real number (single-precision real number)
• 0141H: Floating point real number (double-precision real number)
The completion status is stored upon completion of the instruction.
• 0000H: Completed successfully
• Other than 0000H: Completed with an error (error code)
Specify the number of read-target data (in units of words). The processing unit and
setting range depend on (d1)+0.
■When "Reading binary data" is specified by (d1)+0
• When 16-bit binary data is specified: In units of words (1 to 65535)
• When 32-bit binary data is specified: In units of double words (1 to 32767)
■When "Reading data after converted to CSV format" is specified by (d1)+0
• When decimal (16-bit data) is specified: Number of elements (1 to 65535)
• When decimal (32-bit data) is specified: Number of elements (1 to 32767)
• When hexadecimal (16-bit data) is specified: Number of elements (1 to 65535)
• When hexadecimal (32-bit data) is specified: Number of elements (1 to 32767)
• When a string (ASCII data) is specified: Number of elements (1 to 1023)
• When a floating point real number (single-precision real number) is specified:
Number of elements (1 to 32767)
• When a floating point real number (double-precision real number) is specified:
Number of elements (1 to 16383)
■When "0130H: String (ASCII data)" is specified by (d1)+0
• Total size of the characters in the element (in units of words)
■When data other than "0130H: String (ASCII data)" is specified by (d1)+0
• Fixed to 0
■When "Reading binary data" is specified by (d1)+0
• 00000000H: From the beginning of the file
• 00000001H to FFFFFFFEH: From the specified position (The data unit is
determined by (d1)+7.)
• FFFFFFFFH: Cannot be specified.
■When "Reading data after converted to CSV format" is specified by (d1)+0
• 00000000H: From the beginning of the file
• 00000001H to FFFFFFFEH: From the specified row
• FFFFFFFFH: From the position where the previous reading ends
When "Reading binary data" is specified by (d1)+0, set 0.
When "Reading data after converted to CSV format" is specified by (d1)+0, set the
number of read-target columns.
• 0: No column (Regarded as one row.)
• Other than 0: Number of specified columns
• 0: Word
• 1: Byte
• 2: Unit of the data type specified by (d1)+0
"0: Word" and "1: Byte" can be specified only when "0000H: 16-bit binary data" or
"0100H: Decimal (16-bit data)" is specified by (d1)+0.
