2.2 Correspondence between the Functions and
Class/Member Functions - MX100 -
This section indicates the correspondence between the functions that the software
supports and the class.
Communication Functions
Function Class and Member Function
Connect to the MX100. CDAQMX::open
Disconnect from the MX100. CDAQMX::close
Set the communication timeout. CDAQMX::setTimeOut
Note
Setting of the communication timeout is not recommended because unexpected
disconnection may occur due to the conflict with the timeout time when data is retrieved.
Control Functions
Starting/Stopping the FIFO
Function Class and Member Function
Start the FIFO CDAQMX::startFIFO
Stop the FIFO CDAQMX::stopFIFO
Set auto control of the FIFO CDAQMX::autoFIFO
Other Controls
Function FIFO Class and Member Function
Set time information on the MX100 as the Stop CDAQMX::setDateTime
number of seconds from the reference
date/time (Jan. 1, 1970).
Turn ON/OFF data saving to the CF card
Continue CDAQMX::setBackup
(data backup).
CF write mode
Stop CDAQMXSysInfo:
setCFWriteMode
Format the CF card. Stop CDAQMX::formatCF
• Reconfigure the system of the unit. Stop CDAQMX::initSystem
• Initialize the system of the unit. Stop
• Reset alarms (alarm ACK) of the unit. Continue
The FIFO column in the table indicates the FIFO operation when the function is
executed while FIFO is running.
Stop: The FIFO stops when the function is executed.
Continue: The FIFO continues even when the function is executed.
With the backup settings, the CF write mode represents a partial change of the
collectively obtained data. After changing the data, it must be sent all together.
Note
If the auto control of the FIFO is enabled, the FIFO is automatically resumed when the
FIFO is stopped due to an execution of a function.
