Modbus OPC-server diagram

The DataHub Modbus OPC Server provides reliable real-time bi-directional connectivity between multiple Modbus TCP devices and any OPC enabled applications.

Unique Advantages

  • Eliminates the need for an additional OPC server by connecting Modbus slaves directly to a DataHub instance.
  • Easy and complete configuration of Modbus TCP slave connections.
  • Combines with other DataHub features like Email/SMS, WebView, or External Historian, to optimize the value of your Modbus data.
  • Supports asynchronous socket multiplexing in Modbus TCP to share one TCP connection with multiple Modbus devices. This eliminates cross coupling between client timeouts and provides client timing independence.

Included Features

  • Connects to any number of Modbus TCP slave devices.
  • Connects to any number of OPC server and client programs.
  • Automatic Modbus ↔ OPC protocol conversion built-in.
  • Supports SSL encryption for better security.
  • Easy configuration through manual point-and-click or XML file import.
  • Supports DataHub Scripting.

Popular add-ons

  • Redundancy – enable hot standby switching between identical data sources.
  • Tunnel/Mirror – securely network OPC data without DCOM problems.
  • WebView – build and display private cloud-based web pages.
  • Bridging – connect two or more data sources to share data in real time.
  • OPC A&E – connect to OPC A&E servers and clients.
  • Modbus – connect to Modbus TCP slave devices.
  • Database write – write data to any ODBC database.
  • Database read – read data from any ODBC database.
