The Ignition OPC-UA module offers OPC-UA server functionality with a variety of device drivers and a robust, open driver API.
This module turns Ignition into an OPC-UA server, capable of handling connections from any OPC-UA compatible client. Outgoing connections can also be made to 3rd-party OPC-UA servers. In this way Ignition functions as both an OPC-UA server and an OPC-UA client.
The OPC-UA module offers a number of device drivers for common protocols out of the box, and is easily expandable thanks to the hot-swappable module architecture in Ignition. New drivers can be downloaded and installed in minutes without requiring a system restart or otherwise affecting other parts of the Ignition platform.
The OPC-UA module ties into the Ignition redundancy in order to provide efficient access to device data along with failover redundancy, with no additional configuration.
Anyone can create new drivers thanks to the open driver API, and users can download and install drivers created by other developers. This is the first time such an API has been made publicly available for a product like Ignition. For more information about creating drivers for Ignition, visit the Inductive Automation website.
Drivers for the OPC-UA module are deployed as modules themselves. While they don't add a visible element to the system, they are loaded and upgraded in the same manner as other Ignition modules. A list of available drivers can be found on the Drivers page.
Documentation on the OPC-UA module can be found in the OPC-UA and Device Connections page.
