Binary files are structured very much in the same way as the Input and Output files.
Upon inspection, the only obvious difference is that the Binary file window does not have the Force button at the bottom of the window.
The other difference is in the way the address in the Binary file is shown. There is only one 16-bit word by default in file B3, and it has an address of B3:0. There is no decimal point in the word address as there was with the O0 and I1 files.
Binary file elements are used for internal program use, as these bits are not directly associated with physical inputs or outputs. They are set and reset by the logic in the program.
The file size can be modified.
