Up: Operation Specific Functionality and
Certain OPC properties, namely value, quality, timestamp and
scanRate can be automatically handled by the PyOPC
framework. This way, these four properties will be automatically
available for all OPC items.
The values of these properties will be retrieved as follows:
- The values of the value, quality and timestamp
properties are simply retrieved with the servers read method,
which contains all needed data.
- The value of scanRate is set to MaxSamplingRate.
