ABB has introduced System 800xA 7.0 as its latest Long-Term Support release. The platform combines established control and operator workflows with a modern software foundation, giving process plants a structured way to adopt new capabilities while protecting the stability of core automation.
According to ABB, version 7.0 adds current operating-system and virtualization support, strengthened cybersecurity and connectivity through OPC UA and Ethernet-APL. It is designed for both new facilities and installed bases that need lifecycle modernization without treating every new capability as a disruptive core-platform replacement.
Version 7.0 is ABB’s current LTS release, created as a stable foundation for lifecycle planning and phased modernization.
ABB’s new delivery model can introduce selected functions independently of a core-platform upgrade.
The first Extension Pack provides a zero-install HTML5 Operations Client that supports existing operator graphics and workflows.
OPC UA and Ethernet-APL help connect the control environment with contemporary devices and applications.
The pictured PM857K02 is an ABB AC 800M redundant High Integrity processor kit. ABB identifies article number 3BSE088386R1 and states that its High Integrity functionality requires the appropriate SM812 module, SIL-certified software and configuration according to the Safety Manual.

ABB describes System 800xA 7.0 as a foundation for Automation Extended. The approach uses open standards and containerized technology to keep proven core control separate from optimization capabilities. Plants can therefore evaluate new functions incrementally, while governance, testing and cybersecurity controls remain tied to the approved site architecture.
System owners, operations teams and project engineers should review 7.0 when planning a lifecycle upgrade, replacing aging infrastructure, updating cybersecurity requirements or extending modern connectivity. Before requesting hardware, record the installed System 800xA revision, complete ABB article numbers, controller redundancy, communication interfaces, I/O families, safety classification and required licenses.
ABB positions System 800xA as an integrated automation environment connecting process control, electrical systems, safety functions and operator information. Version 7.0 modernizes the supporting software foundation while retaining established engineering data, displays and operational practices. It is therefore relevant to control rooms, engineering workplaces and virtualized infrastructure, as well as projects built around AC 800M controllers and field-level I/O.
A useful review begins with an accurate installed-base record: the current System 800xA version, server environment, controllers, communication interfaces, I/O families, redundancy arrangement and safety configuration. Teams can then define whether the project is driven by lifecycle support, virtualization, browser-based operations, cybersecurity or new connectivity. Separating the objective from the parts list helps avoid unnecessary replacement and makes compatibility questions easier to resolve before procurement.
