How can I use these ATT ( add to table) and FIFO (first in first out) functions for displaying and rotating 6 digit alphanumeric number or say string/ character? For e.g. SD7389. Thank You

If so then: log(9999)/log2=13,28 bit reolution-> therfore using 16bit number like integer or word is enough. six digit means 999999-> log(999999)/log2=19,93 -> so you have to change your table functions to use 32bit numbers: dint or dword, you would need to alter allthose functions.

Thank You Hello Sandesh11, Iam afraid you cannot use these FC's you mention, because they are fixed to Word type tables. Bellow a very good example that you can easily adapt to different structures. http://support.automation.siemens.com/WW/view/en/16825843
