    Default Best and worst Calcs

    I have a number of Barcode scanners on a system with "no read" stats in a variable.
    What is the best way to show on a screen which scanner has the worst read rate and what that value is

    You can use zenon Logic to calculate your statistics and store the result in zenon variables.

    As I already have all the variables for the scanners already, is there not something I could do with the maths driver?

    Though it might be possible with math driver, it will be much more comfortable using zenon Logic.
    To share your zenon variables with zenon Logic just enable the checkbox "externally visible" in the section "external settings" of the variable properties.
    On then logic side you can enable the logic-to-scada-connection in the fieldbus configuration settings.
    With this you can directly access zenon variables within zenon Logic and therefore you have an easy way to create all the logic functionallity needed in our full blown 61131-3 soft plc.
