C.2 OPC-UA implementation
The OPC-UA feature on OsmoTECH PRO osmometers
connects the instrument to an OPC-UA client.
The instrument can send the following types of data to
an OPC-UA client or any data management middleware
that understands OPC.
• Test results
• Sample ID and user ID (test results)
• Test details (test results)
• System test count (total number of tests performed)
• Error code (for instrument)
• Serial number
• Software revision and firmware revision
• Date of last calibration

requiring notification and
acceptance by local user.
IDs ‘;’ delimited values Send sample IDs to remote
instrument as part of running a
series of tests.
START/CANCEL Start/cancel of tests with
continuous live monitoring of
test progress
Import test result values from remote osmometer database
based on date/time input.
