    In this field:
    Specify:
    PV unscaled maximum
    Enter a maximum PV value (.MAXI) that equals the maximum unscaled value received from the analog input channel for the PV value.
    PV unscaled minimum
    Enter a minimum PV value (.MINI) that equals the minimum unscaled value received from the analog input channel for the PV value.
    PV engineering units maximum
    Enter the maximum engineering units corresponding to .MAXI (.MAXS).
    PV engineering units minimum
    Enter the minimum engineering units corresponding to .MINI (.MINS).
    CV maximum
    Enter a maximum CV value corresponding to 100% (.MAXCV).
    CV minimum
    Enter a minimum CV value corresponding to 0% (.MINCV).
    Tieback maximum
    Enter a maximum tieback value (.MAXTIE) that equals the maximum unscaled value received from the analog input channel for the tieback value.
    Tieback minimum
    Enter a minimum tieback value (.MINTIE) that equals the minimum unscaled value received from the analog input channel for the tieback value.
    PID Initialized
    If you change scaling constants during Run mode, turn this off to reinitialize internal descaling values (.INI).
