- ”Repeat end” event
This even occurs whenever a repetition is completed.
- ”End of device operation” event
This event occurs when the entire operation including repetitions is completed.
- "Specified number of output samples complete" event
This event occurs when the number of output samples specified by software have been completed.
- Sampling clock error event
This event occurs when conversion stops as an error occurs due to a sampling clock period that is
too short.
- DA conversion error event
This event occurs when conversion stops due to a DA conversion error.
2. Starting/Stopping Operation
Analog output operation is started by a software command (the analog output start command).
Similarly, you can stop analog output at any time using a software command (the analog output stop
command).
3. Monitoring the Status and Acquiring Data
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:
- Device operating
The “device operating” status remains ON, after the execution of the sampling start command until
the product completes conversion, aborts operation due to an error, or stops sampling in response to
the command.
- Waiting for start trigger
This status remains ON, after the product starts sampling until the start trigger is input, if the
conversion start condition is an external trigger. The status is set to OFF when the input trigger is
input to start conversion.
The status is set to ON whenever the product enters the conversion start wait status even when
repeated operation has been set.
- Specified number of data outputs
This status turns ON when the output data set in memory has reached a predefined number of
samples.
- Sampling clock error
This error occurs when the sampling clock period is too short.
