Hello Mikhail,

I want compare previous value of channel-1 with the current value of channel-1.. and after comparison i want to store the highest value.

(pre_data_cha1 > cur_data_cha1) ? pre_data_cha1 : cur_data_cha1. I got answer for this by your reply Val() > Cnl ? Val() : Cnl.

now i want to save that highest value in excel sheet with time. how to show time in excel sheet.

Hi,

If you need to save a time when value is maximum, you need additional channel and more complex formula. Something like that:

  double GetMax(int timeCnl)
  {
    if (Val() > Cnl)
    { return Val(); }
    else 
    { 
      SetVal(timeCnl, EncodeDate(DateTime.Now));
      return Cnl; 
    }
  }
