Setting any values within a range of ±32,000 as the upper and lower limits allows D/A conversion to be executed and analog signals to be output with these values as full scale. Ratio conversion function *5 Stores the results of positive and negative gradient analog inputs calculated for ratio and bias as analog output values. Positive gradient: Analog output = A × Analog input + B (A: 0 to 99.99, B: 8,000 to 7FFF hex) Negative gradient:Analog output = F − A × Analog input + B (A: 0 to 99.99, B: 8,000 to 7FFF hex, F: Output range maximum value) *1. Input and output signal ranges can be set for each input and output. *2. The accuracy is given for full scale. For example, an accuracy of ±0.2% means a maximum error of ±8 (BCD) at a resolution of 4,000. *3. D/A conversion time is the time required for converting and outputting the PLC data. It takes at least one cycle for the data stored in the PLC to be read by the Analog I/O Unit. *4. When the operation mode for the CPU Unit is changed from RUN mode or MONITOR mode to PROGRAM mode, or when the power is turned ON, the Output Conversion Enable Bit will turn OFF. The output status specified according to the output hold function will be output. *5. By means of the D(m+18) setting, the resolution can be changed to 8,000, and the conversion time can be changed to 500 μs. 14 CJ1W-AD/DA/MAD I/O Function Block Diagram Analog I/O Unit Input disconnection detection Analog input 1 Mean value processing disabled CPU Unit Peak value hold function disabled Scaling enabled I/O refresh A/D Scaling disabled Analog input 2 Same as above.
