Description
Overview
Data retrieval is possible by starting the FIFO. The amount of retrievable data within
the FIFO data on channel 1 of the MX100 is retrieved and stored in the field. Gets
the measured value data (one point) of the current status (first measurement point)
and concludes the process.
Communication Connection
int comm = DAQMX100.openMX100(enc.GetBytes(address), out rc);
The IP address of the MX100 is specified. This statement implicitly specifies the
communication constant DAQMX_COMMPORT (communication port number of the
MX100).
FIFO Start
rc = DAQMX100.measStartMX100(comm);
Starts the FIFO on the MX100.
