Golang使用Apache PLC4X连接modbus

Apache PLC4X 是一个工业物联网通用协议适配器，PLC4X 是一组库，用于使用各种协议与工业可编程逻辑控制器 (PLC) 进行通信，但这些协议具有共享的 API。

工业的可编程逻辑控制器（PLC）大多采用大量不兼容的协议进行通信，因此和外界（IT/互联网）的交互变得很困难。PLC4X 项目致力于提供一组统一的 API，通过这些 API 实现能与大多数 PLC 进行通信的驱动程序（通过各种 PLC 的原生通信协议）。

	// Register the Drivers
	drivers.RegisterKnxDriver(driverManager)

	// Get a connection to a remote PLC

	// If all was ok, get the connection instance
	connection := connectionResult.Connection

	// Make sure the connection is closed at the end
	defer connection.Close()
