A Raw ASCII example displays in the second column of Table Comparing Raw and Command ASCII Files for One Board.
Raw ASCII files contain channel data organized as one line per step. The number of file lines always equals the number of steps. Each line contains the same number of characters, equal to the number of domain channels configured. Channel Data is represented by one of three ASCII characters: “0”, “1” or “X”. “0” and “1” are logic states. “X” represents either “don’t care” (GC5050/GX5050) or “open” (GX515X) and normally occurs in ASCII files that are converted from DIO (not DI) files.
Channel Data is saved in bit order. The highest order channel is at the left near the beginning of the line. That channel is the highest channel number on the highest board number. The lowest order channel, Board 0 - Channel 0 (Master board), is at the right end of the line. There can be up to 256 characters per line for a fully populated domain. The default file size is 16,384 steps (lines). The file size ranges from 1,024 lines to the largest number of steps supported in the target domain.
