Using arrays in rslogix5000

[oxlacey]

I created a tag called rack_and_contents which is a 13,1 array.

I want to put into this array, a rack # (int) and its corresponding contents (int).

what is the instruction and syntax i would use?

Do you want to put the Contents into the array at the rack# position or to you want and array filled with (rack#,contents)?

If you want to store contents AT the rack# position then you can use many many ways to enter elements into the array one such is

MOV(contents,rack_and_contents[rack#])

otherwise you should make a 2d array rack_and_Conents[x,2]
and put rack# in at rack_contents[x,0]
and contents in at rack_and_contents[x,1]

As for what specific instruction. As long as destination field is the element in the array you want the result will get stored there

For ease of reading later I would create a UDT with two members, rack and contents. Then make a single dimension array of this UDT.
