Data Formats of ASCII Files
This section describes the data format of the ASCII file. The RD-MV100 creates two
types of ASCII files, the manual sampled data file and the report file.
Data Format of the Manual Sampled Data File
• The manual sampled data are output in ASCII format using values and strings that are
separated by commas.
• The channel/tag, unit, and manual sampled values are not output for channels in
which the input range is set to [Skip] or for which the computation is turned OFF.
Example
The following example is for channels 1, 2, 3, 4, and 31.
“MANUAL SAMPLE DATA”
“Model Serial No.:”, “XXXXXXXXXXXXXXXX”
“File Header : ”, “AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA”
“CH/TAG”, 1 “CH01 ”, “CH02 ”, “CH03 ”, “CH04 ”, “CH31 ”
“UNIT”, “V ”, “V ”, “V ”, “V ”, “mV ”
2000/01/01 01:08:43, 0.000, 0.000, 0.000, -0.014, 12.00
2000/01/01 01:08:48, 0.000, 0.000, 0.000, -0.014, 12.00
2000/01/01 01:09:15, 0.000, 0.000, 0.000, -0.014, 12.00
“CH/TAG”, 1 “CH01 ”, “CH02 ”, “CH03 ”, “CH04 ”, “CH31 ”
“UNIT”, “V ”, “V ”, “V ”, “V ”, “V ”
2000/01/01 01:15:30, 0.000, 0.000, 0.000, -0.014, 12.00
2000/01/01 01:18:12, 0.000, 0.000, 0.000, -0.014, 12.00
Data size
• Size of the header section
The following equation can be used to derive the size of the header section.
Title + carriage return line feed + serial carriage return line feed + file
carriage return line feed + channel/tag (8 + 19
×
number of channels
that are output) + carriage return line feed + unit (6 + 9
×
number of channels
that are output) + carriage return line feed
• The size of the title is fixed to 20 bytes.
• The size of the serial number is fixed to 38 bytes.
• The size of the file header is fixed to 49 bytes.
• The size of the carriage return line feed is fixed to 2 bytes.
Calculation example
Manual sampled data for 30 channels
20 + 2 + 38 + 2 + 49 + 2 + (8 + 19
×
30) + 2 + (6 + 9
×
30) + 2 = 971 bytes
• Size of the data section of one data set
The following equation can be used to derive the size of data section of one data set.
Date and time of manual sa measured value(8
×
number of
measurement channe) + computed value (10
×
number of computation
channels) + carriage return line feed
• The size of the date and time of creation is fixed to 19 bytes.
• The size of the carriage return line feed is fixed to 2 bytes.
Calculation example
Manual sampled data for 30 measurement channels
19 + (8
×
30) + (10
×
0) + 2 = 261 bytes
