Return values	Content
0	Normality completion
7	Execute AioResetDevice function because the device has recovered from standby mode
10001	Invalid Id was specified Use the Id retrieved from AioInit to specify the Id in this function.
10002	AIO driver can't be called At first, perform AioInit function.
17010	The value of Input is outside the designated range of the function
17011	Pointer to Source is NULL Specify the address of variable to parameter.
20001	This function can't be used by this device
20002	Can not use while by another device works To use this function, analog input and output, counter, timer operation must be stopped.
20003	Can not use because another process is using the device When another process is using the device, all functions except for those that support multi-process can not be performed.
27010	The value of Destination is outside the designated range of the device being used

Remarks

If the device is in operation, the function cannot be performed.

Example

The Source signal connected with the analog output generating clock period is acquired.
