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
comm = openDA100("192.168.1.11", &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 = 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.
Reading Measured Values
value = dataValueDA100(comm, 0, 1);
Reads the measured value of channel 1 of subunit number 0 from the field where
the measured data is stored.
Comm. cut
rc = closeDA100(comm);
Drops the connection.
