OPC UA Module
Cross-Platform OPC UA Functionality
The Ignition OPC UA module offers OPC UA server functionality with a variety of device drivers and a robust, open driver API.
OPC UA Server Functionality
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 third party OPC UA servers. In this way Ignition functions as both an OPC UA server and an OPC UA client.
Built-in Device Drivers
The OPC UA module provides a suite of standard device drivers for common industrial protocols and is easily expandable thanks to Ignition’s modular architecture. New drivers can be downloaded and installed in minutes without affecting other parts of the platform. However, changes to a module's status, such as Active, Inactive, or any Pending Restart state, only take effect when the Gateway restarts. If a restart is required, a banner will appear at the bottom of the Gateway, allowing you to apply the changes immediately.
Restarting the Gateway may temporarily interrupt running services.
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 the included drivers on install can be found on the Driver Modules page.
Redundancy Support
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.
Public Driver API
Ignition provides a public driver API that allows developers to create custom device drivers for the OPC UA module. These drivers can be installed like any other module and used to support proprietary or specialized protocols. Developers can also share drivers with others or integrate them into third party solutions. For more information about developing custom drivers, visit the Inductive Automation website.
