File 7, the Integer file, is structured just like the B3 binary file, except the data is integer data.
An integer may have a value of -32768 up to 32767.
Just as with the Binary file, we can change the Radix to view the data in its binary form.
As part of the ladder program, we can use the individual bits of an integer word from the N7 file just like we would use a binary data bit from the B3 file.
F8 is the floating-point data file.
Floating-point data cannot be shown in any other manner than floating-point, or real number notation.
Floating-point numbers greater than 9,999,999 are shown in scientific notation.
