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 shown. There is only one 16-bit word by default in file B3, and it has an address of B3:0. There is no decimal point in the word address as there was with the O0 and I1 files.
Binary file elements are used for internal program use, as these bits are not directly associated with physical inputs or outputs. They are set and reset by the logic in the program.
The file size can be modified.
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...
The counter structure is similar to that of the timer because it also has a preset and accumulator value, also called PRE and ACC.
There are several bits that are set by the counter, including:
CU for counting up,
CD for counting down,
DN to indicate that the counter has reached the preset val...
