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
int comm = DAQDA100.openDA100(enc.GetBytes(address), out rc);
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.measInstChDA100(comm, 0, 1);
Retrieves instantaneous values of the measured data from channel 1 of DARWIN
subunit number 0 and stores them in the field.
