This package can control devices that support the OPC UA protocol.
It can connect to a device accessible via TCP/IP given the host and port number and send requests using the OPC UA protocol to perform several types of operations with the device.
Currently it can:
- Read and write values supported by the device like temperatures, pressures, motor speeds, setpoints, and counters.
- Discover what devices are available in the network
- Subscribe to change of values in the devices
- Run operations on the devices
- Query historical data like logs and trends on aggregated values and get values from specific times using interpolation |
