The size of files in bytes can be calculated with the equations in the following
table.
File type
Data files (.IOM)
Data files (.TXT or .CSV) The file size depends upon the number of delimiters and
Program files (.OBJ)
Parameter files (.STD)
Note Calculate the number of steps in the program file by subtracting the available
UM steps from the total UM steps. These values are shown in the CX-Pro-
grammer's Cross-Reference Report. Refer to the CX-Programmer Operation
Manual for details.
1. General-purpose data files have filename extensions IOM, TXT, or CSV.
(The TXT and CSV files: Not supported by CS-series CS1 CPU Units that
are pre-EV1.)
CS/CJ-series data format
File size
(Number of words × 2) + 48 bytes
Example: Entire DM Area (D00000 to D32767)
(32,768 words × 2) + 48 = 65,584 bytes
carriage returns being used. The delimiter code is one
byte and the carriage return code is two bytes.
Example 1: Non-delimited words, no carriage return
123456789ABCDEF012345678 occupies 24 bytes.
Example 2: Delimited words, carriage return every 2 fields
1234,5678↵
9ABC,DEF0↵
1234,5678↵
occupies 33 bytes.
Example 3: Delimited double words, carriage return every
2 fields
56781234,DEF01234↵
56781234↵
occupies 29 bytes.
(Number of steps used × 4) + 48 bytes (See note.)
16,048 bytes
