Functions Output hold function Outputs the specified output status (CLR, HOLD, or MAX) under
any of the following circumstances.
When the Conversion Enable Bit is OFF. *8
In adjustment mode, when a value other than the output number
is output during adjustment.
When there is an output setting error or a fatal error occurs at
the PLC.
When the CPU Unit is on standby.
When the Load is OFF.
Other Functions Ratio conversion function 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 max.

*1. Refer to Dimensions for details on the Unit's dimensions.
*2. The maximum number of Analog I/O Units that can be mounted to one Rack will varies depending on the current
       consumption of the other Units mounted to the Rack.
*3. Input and output signal ranges can be set for each input and output.
*4. Voltage input or current input are chosen by using the voltage/current switch at the back of the terminal block.
*5. The Analog I/O Unit must be operated according to the input specifications provided here. Operating the Unit outside
       these specifications will cause the Unit to malfunction.
*6. The accuracy is given for full scale. For example, an accuracy of ±0.2% means a maximum error of ±8 (BCD).
       The default setting is adjusted for voltage input. To use current input, perform the offset and gain adjustments as
*7. A/D conversion time is the time it takes for an analog signal to be stored in memory as converted data after it has
       been input. It takes at least one cycle before the converted data is read by the CPU Unit. 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.
*8. 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.
*9. Input disconnection detection is valid only when the 1 to 5-V or 4 to 20-mA range is set. If there is no input signal for
       when the 1 to 5-V or 4 to 20-mA range is set, the Disconnection Detection Flag will turn ON.
