In the last lesson, we briefly described the data files. Now, we will describe these files in more depth and show how they are used.
Note that each data file is described by a letter followed by a number.
The letter indicates the type of data represented by that file, and the number represents the file number.
For a MicroLogix 1100, data file numbers 0 to 255 are allowed. Files 0 through 8 are predefined. The remaining file numbers can be configured to any data type, except Input and Output.
