function readAnalogWriteAnalog(inputChannels, outputChannels, inputVoltages, outputVoltages); |
Parameters
- inputChannels
- Type: array<
System..::.Int32
>[]()[]
An array containing the numbers of the analog input channels to be read. Channel numbers are zero-based. Thus, channel 0 is the first channel, channel 1 the second channel, etc.
Select a board type to the list for board-specific details: .
- outputChannels
- Type: array<
System..::.Int32
>[]()[]
An array containing the numbers of the analog output channels to be written. Channel numbers are zero-based. Thus, channel 0 is the first channel, channel 1 the second channel, etc.
Select a board type to the list for board-specific details: .
- inputVoltages
- Type: array<
System..::.Double
>[]()[]
An array for receiving the voltage values read from the analog inputs. Each element in the inputVoltages array corresponds to the same element in the inputChannels array. Hence, there must be as many elements in the inputVoltages array as there are channels.
- outputVoltages
- Type: array<
System..::.Double
>[]()[]
An array containing the voltage values to write to the analog outputs. Each element in the outputVoltages array corresponds to the same element in the outputChannels array. Hence, there must be as many elements in the outputVoltages array as there are channels.
Remarks
The ReadAnalogWriteAnalog method reads from the specified analog input channels and writes to the specified analog output channels immediately, in a single method call. The write operation occurs immediately following the read operation. Since the read-write operation occurs at the lowest level the read and write occur virtually concurrently. The method does not return until the data has been read and written.

Exceptions
Exception | Condition |
---|---|
Quanser.Hardware..::.HilException | If the read or write cannot be performed then an exception is thrown. This situtation typically arises if the board does not support this method. |
