Are there any differences between Bit Files and Integer Files other than the way RSLogix displays the information?

as far as i;ve noticed that's the only difference (default view is different)

There are a few subtle differences within the RSLogix software, i.e. where and how you can use different data file types. For example, you cannot address Bx:x as the control block word for a MSG or PID instruction, but you can use Nx:x.
