Output file 0 and Input file 1 are defined to hold values from physical I/O cards.
All of the data files are presented in much the same way. The Output file holds values that are associated with physical output cards. For a MicroLogix 1100, up to 64 outputs, or four 16-bit output words, can be configured.
The Output file is a special case of a binary file, since each individual output address, or element, represents the binary state of an output.
Another feature of data files is the ability to add a description and symbol for each element.
The other common feature of data files is the ability to display the values in the data file in different formats.
The structure of the Input file is the same as the Output file.
File I1 represents the physical input device addresses possible.
Notice that there are six 16-bit input words available, representing the possible 96 inputs for the PLC.
In a later lesson, we will add descriptions and symbols f...
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 show...
In the previous section of this course, we gave a tour of the RSLogix 500 output, input, and binary files. We demonstrated how individual elements of these file types are referenced, how to change the view of the data file from bitwise to decimal, and how to expand the size of certain data file t...
