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 for the input addresses.
The actual number of inputs and outputs in a MicroLogix 1100 system depends on the hardware configuration chosen for the PLC and the number and type of I/O cards installed.
For this program example, only the embedded I/O will be considered.
Other features of the data file window for inputs and outputs will be demonstrated in a later lesson, such as the Forces button.
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...
The elements for the single timer that is configured by default include EN, TT, DN, BASE, PRE, and ACC.
A timer is used to control the timing of a logic event.
For a MicroLogix 1100, the Preset element can be set from 0 to 32767.
Each timer requires three words of memory.
The first word hol...
