Convert Tag Value into Input Variable - musfiq - 10-10-2017 Hi There, How does the eWon tag value is converted to actual value feedin. For example, for a analog input I got a value of 50.93 (which is corresponding to around 3.8 volts inputs). But for voltage signal the multiplication factor is 0.0024420 (10/4095). Provided offset = 0, 50.93 yields 50.93*0.0024420+0 (offset) = 0.1244V. Therefore, there is some other factors which contribute to the translate the eWon value into the input quantity. Could anyone help how to scale the eWon value to the input quantity for voltage and current. Regards Musfiq RE: Convert Tag Value into Input Variable - ziozetti - 31-10-2017 You can find HERE at pages 20-21 how analogic inputs are scaled. Which is maximum Raw Value (AI) in your analog input board? |
