Industrial protocol drivers for .NET 10, written for Native AOT: no reflection, no runtime code generation, real async socket I/O and structured errors that say what failed, why, and what to try next.
| Package | What it does |
|---|---|
Proxus.Drivers.Abstractions |
Protocol-neutral values, quality, timestamps, errors and the common driver contract |
Proxus.Drivers.Core |
Socket and timeout plumbing shared by the drivers |
Proxus.Drivers.Modbus |
Modbus master over TCP, with RTU and ASCII framing through a gateway or a stream you open |
Proxus.Drivers.OpcUa |
OPC UA Binary client: SecureChannel (None, Basic256Sha256, Aes128_Sha256_RsaOaep, Aes256_Sha256_RsaPss), Session, Read, Write, Browse, subscriptions, history, methods and events |
None of the packages depends on another library.

Every capability carries an evidence level (definitions), from deterministic tests to independent interoperability against libmodbus, PyModbus, open62541, asyncua and the OPC Foundation reference server. The protocol guides say which level each feature has reached. A simulator is not a physical device, and the guides do not pretend otherwise.
dotnet build Proxus.Drivers.slnx -c Release
dotnet run --project tests/Proxus.Drivers.Modbus.SelfTests -c Release --no-build
dotnet run --project tests/Proxus.Drivers.OpcUa.SelfTests -c Release --no-buildlab/servers holds the container recipes for the PyModbus and open62541 servers used in interoperability runs.
These drivers are the open part of the driver set inside Proxus, the on-premise industrial data platform: device connectivity, a Unified Namespace, historian, dashboards and governed AI access in one product. Siemens S7, EtherNet/IP, CNC controls and the other protocols ship with the platform.
