See https://github.com/gopcua/opcua/wiki/Supported-Devices - to get a list of devices/applications we have tested various crypto and authentication - methods. Please add your own. See `examples/crypto` for an example. - * Debug messages are now disabled by default. - -We are getting closer to use this for our first production use cases. Subscription support -is certainly high on the list for the client as is a Server implementation. Let us know what -is missing right now to make this library useful for you and we can focus on this first. - -### Current State (20 Mar 2019) - -Our goal is to make this the native Go library for OPC/UA. - -This code is not ready for production but we intend to get it there. - -We are testing the code against real-world PLCs and other OPC/UA -implementations but this needs to be more formalized. The goal is to have the -examples working with real PLCs. Please let us know if they don't. - -We are working on the library and some things are working but others are not. - -Here is what currently works: - - * client connection handshake, create secure channel and session - * async request/response dispatching on the secure channel - * support for chunking when receiving (not sending) - * all structures and enums are generated from official OPC Foundation defintions - * basic `uasc` listener available but no server implementation - * start of a high-level Client implementation. See `client.go` and - `examples/datetime` for a usage example. - * decent tests of the binary protocol codec - -Here is what is not yet working: - - * `ERR` messages are not yet bubbled up to the caller (not hard but need to do it) - * service calls need to check `ServiceStatus` and bubble that error up (also not hard) - * no security protocol support. @dwhutchinson provided the crypto code but it needs to be - integrated into the network layer. - * no high-level server implementation, address space, etc. +The [Current State](https://github.com/gopcua/opcua/wiki/Current-State) was moved +to the [Wiki](https://github.com/gopcua/opcua/wiki). ## Your Help is Appreciated
