Description
Overview
Retrieves instantaneous values of the measured data from channel 1 of DARWIN
subunit number 0 and stores them in the field. Reads the measured values and
concludes the process.
Communication Connection
rc = daqda100.open("192.168.1.11");
The IP address of the DARWIN is specified. This statement specifies the
communication constant for the port number for loading the instantaneous value
data.
Retrieval of the Measured Data of Channel 1
rc = daqda100.measInstCh(0, 1);
Retrieves instantaneous values of the measured data from channel 1 of DARWIN
subunit number 0 and stores them in the field.
Reading Measured Values
value = ((daqda100.getClassDataBuffer(0, 1))-
>getClassDARWINDataInfo()).getValue();
Reads the measured values of channel 1 retrieved from various types of information
on channel 1 through the measured data.
