Siemens has launched version 4.0 of its SiMATIC PCS neo control system, which promises to accelerate digital transformation and optimise plant processing efficiencies. The system is designed to prepare plants for the future, helping to facilitate collaboration and to alleviate shared industry challenges such as modular automation, scalability, interoperability, integration, and lifecycle management.

The new SiMATIC PCS neo control system v4.0 addresses shared challenges in the process industries.
Rowan Dickason, Vice President for the Process Automation Business Unit at Siemens, says, “This state-of-the-art control system is more sustainable than the previous version and embraces globalisation with its fully fledged web-based platform. The new control system encompasses a re-thinking of process automation technology, to include digitalisation, interoperability, collaboration, and agility. It integrates seamlessly with existing systems and allows multiple processes to happen simultaneously. It is the future of process automation – and we believe it will be a game-changer going forward.”
The system supports all aspects of the Module Type Package (MTP) standard, allowing for easy integration which can be achieved independently of the respective device manufacturer. This supports a ‘plug and produce’ methodology and enables workflow improvements that reduce the required engineering further.
Efficiency is core to all Siemens’ designs. The new Simatic S7-4100 automation system defines a new generation of controllers for the process industry, with the first release available exclusively for the Simatic PCS neo. The new controller is 30% smaller than the previous model, with extended communication capabilities. It also reduces energy consumption by up to 50%. Importantly in the South African context, it is robust, maintenance-free, and no batteries are required to buffer system data in the event of a power failure. Dickason adds, “The controller is the ‘brain’ of the process plant. Our Simatic S7-4100 controller takes this to a new level of performance.”
In addition to the SIMATIC PCS neo v4.0, Siemens is releasing its fully integrated SIMATIC CN 4100 communication gateway. This facilitates a simple and secure data exchange with SIMATIC PCS neo, playing the role of a convenient data switch. That means data from the plant can be fed simultaneously from the plant to the controller and the process control system. Supported protocols include Modbus TCP and OPC UA, with more planned.
Dickason says, “We designed these systems to streamline process control, simplify engineering and increase security. For process industries, the new control system can be used for individual process modules or world-scale plants. It is the first completely web-based system that enables location-independent engineering and process control. Users can access the data anywhere, anytime, which marks a new paradigm in the process automation environment. It is in line with Siemens’ philosophy to focus on innovative technology with purpose. We’re consistently seeking smart ways to create value. SIMATIC PCS neo does that.”
