Monitoring the Status
You can use a software command to check the status of analog output operation and of the output data
stored in memory.
Status
The current state of the device can be checked by obtaining the device status.
The following types of device status are available:
- Analog output operating
This status remains ON, after the board performs the analog output start command until the analog
output operation is stopped.
- Waiting for start trigger
This status remains ON, after the board performs the analog output start command until the
sampling start condition is satisfied, if the sampling start condition is an external trigger. The
status is set to OFF when the external trigger is input to start sampling.
This status is set to ON whenever the board enters the conversion start wait status even when
repeated operation has been set.
- Specified number of data items already output
- Sampling clock error
This error occurs when the analog output operation stops as the sampling clock cycle is too short.
- DA conversion error
This status is turned on when the analog output operation stops upon detection of a device
malfunction by the driver.
Sampling count
The number of sampled items of output data transferred from in memory can be obtained by the
software command.
Repeat
The current repeat count can be obtained by the software command.
