OPC DA in GoRead and write process and automation data in Go from an OPC server for monitoring and data analysis purposes (OPC DA protocol).go get github.com/konimarti/opcUsageclient, _ := opc.NewConnection( "Graybox.Simulator", // ProgId []string{"localhost"}, // Nodes []string{"numeric.sin.float"}, // Tags)defer client.Close()client.ReadItem("numeric.sin.float")browser, _ := opc.CreateBrowser( "Graybox.Simulator", // ProgId []string{"localhost"}, // Nodes )opc.PrettyPrint(browser)Installationgo get github.com/konimarti/opcTroubleshootingOPC DA Automation Wrapper 2.02 should be installed on your system (OPCDAAuto.dll or gbda_aut.dll); the automation wrapper is usually shipped as part of the OPC Core Components of your OPC Server.You can get the Graybox DA Automation Wrapper here. Follow the installation instruction for this wrapper.Depending on whether your OPC server and automation wrapper are 32-bit or 64-bit, set the Go architecture correspondingly:For 64-bit OPC servers and wrappers: DLL should be in C:\Windows\System32, use $ENV:GOARCH="amd64"For 32-bit OPC servers and wrappers: DLL should be in C:\Windows\SysWOW64, use $ENV:GOARCH="386"Make sure to have correct DCOM settings on your local and remote computers: Dcomcnfg.exeReporting IssuesIf you find a bug in the code, please create an issue and suggest a solution how to fix it.Issues that are related to connection problems are mostly because of a faulty installation of your OPC automation wrapper or some peculiarties of your specific setup and OPC installation. Since we cannot debug your specific situation, these issues will be directly closed.DebuggingAdd opc.Debug() before the opc.NewConnection call to print more debug-related information.TestingStart Graybox Simulator v1.8. This is a free OPC simulation server and require for testing this package. It can be downloaded here.If you use the Graybox Simulator, set $GOARCH environment variable to "386", i.e. enter $ENV:GOARCH=386 in Powershell.Test code with go test -vExamplepackage mainimport ( "fmt" "github.com/konimarti/opc")func main() { client, _ := opc.NewConnection( "Graybox.Simulator", // ProgId []string{"localhost"}, // OPC servers nodes []string{"numeric.sin.int64", "numeric.saw.float"}, // slice of OPC tags ) defer client.Close() // read single tag: value, quality, timestamp fmt.Println(client.ReadItem("numeric.sin.int64"))

Interface. This means that if the OPC Data Access Custom server supports the interface, the functions and properties at the automation level will work. However, it's worth noting that automation interfaces do not support optional capabilities in the same way that the custom interface does. In other words, some optional functionality may be omitted when using the automation interface. If this happens, the corresponding automation functions and properties will exhibit some reasonable default behavior.To use this software, all you need is the Graybox OPC DA Auto Wrapper DLL-module. All the necessary OLE-objects are already implemented in the module. Once you register the module, you'll be able to use any OPC Data Access Server with virtually any OLE enabled programming language including Visual Basic and VBA, among others. In summary, the OPC DA Auto interface is a great tool for anyone looking to improve the functionality of their OPC Data Access Custom Interface Servers. Its automation-friendly mechanism is user-friendly and ensures that almost all required and optional Interfaces are readily available. What's New Version 1.3: 1.
