you can measure only analog voltage input siganl in MM440. to measure the 4-20mA signal input, please connect via a resistive network to generate a 0-10V signal with help of 500 ohm resistor. Please follow the parameters to get the 0-10V analog input setting as below. P0756 = 0 (unipolar voltage input 0 - +10V) P0757 = 0V (minimum analog input voltage) P0758 = 0% (the scaled minimum percantage corresponding to your minimum input signal) P0759 = 10V (the maximum input voltage) P0760 = 100% (the scaled maximum in percentage representing your maximum output value) After this, you will be able to see your actual input in voltage and also in the scaled value (that you had set in above parameter) r0752 = actual input voltage (in volts) r0754 = actual value after scaling (in %) these two datas are readonly data. Find the MM420 parameter list to get more info Parameter List: MICROMASTER 420 rgds, RBM |
