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 DARWIN communication port number.
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 the Measured Value
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.
