Good morning All,

I am currently attempting to convert an old PLC-5 processor to a ControlLogix processor. I have the program converted to the new processor type, but I've ran into an issue with a LEQ statement N[N7:52]:[N7:54]. The number it is comparing itself to is 221 and its averaging at 218 in the PLC-5 program but when i look at the variables that are shown in the program the numbers do not add up averaging 51 for N7:52 and 39 for N7:54. Would this statement be preforming multiplication and then a division to get the average number? I am asking out of complete inexperience with PLC-5 and the conversion method.

Thank you
