The CUeiVRReader object can read the following types of data:
• Read()– converted VR sensor data, raw data, FIFO data, or ADC
voltage data
• ReadTorque()– torque sensor data
•
ReadADCStatus() – diagnostic data from the ADC
•
ReadAlarmStatus() – check for triggered alarms on VR input lines
•
ReadDigitalInputStatus() – read status of digital inputs
• ReadRevision() – read DNx-VR-608 revision
If you pass a tUeiVRData structure into the overloaded Read() method, the
reader returns a structure (a cluster in LabVIEW) containing the velocity,
position, total tooth count since the session started, time stamp, and open/
closed circuit flags.
You can print the data as follows:
Some of the structure members will not have data in every mode. When there is
no data, they will be set to 0. This is summarized in Table 4-5.
