5.4 File Operations by GX Developer and Handling Precautions 5.4.4 Units of file sizes
2) Calculation of program size
The program size is found by the formula: sequence program size + reserved area for online change.
Since files are stored in units of file sizes to the program memory, the parameter file size is 525 steps + 500
steps = 1025 steps. However, the file occupies 1536 steps/6144 bytes.
3) Result
The calculation results of the memory capacities are as shown below.
