Description
Overview
Data retrieval is possible by starting the FIFO. The amount of retrievable data within
the FIFO data of the MX100 channel 1 is retrieved and stored in the field. Gets the
measured value data (one point) from the first measurement point of the current
status and concludes the process.
Communication Connection
rc = daqmx100.open("192.168.1.12");
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
daqmx100.measStart()
Starts the FIFO on the MX100.
Retrieval of the Measured Data of Channel 1
rc = daqmx100.measDataCh(1);
The amount of retrievable measured data from channel 1 of the MX100 is retrieved
and stored in the field. The first measurement point is set as the current status.
