The evolution of industrial automation has reached a level where the distinction between floor-level control and data analysis is becoming increasingly seamless. Within this transformation, Altus consolidates its position with the launch of the first Nexto XF models, a series of controllers designed to operate as distributed intelligence platforms, fully prepared for the emerging challenges of Industry 4.0.
This article serves as a practical guide, leading new users from the moment of equipment acquisition to the mastery of its core functionalities. it compiles tutorial content, technical documentation, and audiovisual resources developed by our technical support team to date.
The goal here is to answer a simple question: now that the Nexto XF series is available on the market, how can you, as a user, extract the maximum potential from your hardware?
The answer lies in an extensive library of resources, ranging from videos produced by the technical support team to detailed manuals on communication protocols and cybersecurity, providing the necessary support to accelerate the learning curve and maximize application performance.

I bought my XF, now what? Where to start? (First steps)
Mastertool download
Languages and the IEC 61131-3 standard
Flexibility is the key to operational innovation, and Mastertool embodies this principle by offering full support for the five programming languages standardized by the IEC 61131-3 norm: Structured Text (ST), Sequential Function Chart (SFC), Function Block Diagram (FBD), Continuous Function Chart (CFC), and Ladder Diagram (LD).
With this diversity, you can employ different languages within the same application, organizing projects, reusing previously developed code, and ensuring that your team, even with different specializations, can collaborate efficiently by choosing the most suitable language for each segment of the control logic.
