The scalability of the Altus\u2019 solution ensures you can evolve from basic to more advanced versions as your projects grow, while maintaining the same software platform. <\/p>\n\n\n\n

Five languages, the IEC 61131-3 standard, and the power of CFC<\/strong> <\/h2>\n\n\n\n

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 standard: Structured Text (ST), Sequential Function Chart (SFC), Function Block Diagram (FBD), and Ladder Diagram (LD). And as a bonus, it includes the Continuous Function Chart (CFC) extension. <\/strong> <\/p>\n\n\n\n

With this diversity, you can use different languages within the same application, organizing projects, reusing previously developed code, and ensuring that your team, even with different specializations, can collaborate efficiently, choosing the most suitable language for each segment of the control logic.  <\/p>\n\n\n\n

Object-Oriented Programming: reusability and scalability<\/strong> <\/h3>\n\n\n\n

Imagine building complex systems with the same ease as assembling a set of blocks. This is the essence of Object-Oriented Programming (OOP) in MasterTool IEC XE. Integrated from programming features to the organizational structure of projects, OOP allows you to create functional blocks with properties, methods, inheritance, and method invocation.  <\/p>\n\n\n\n

Program Organization Units (POUs) are the fundamental objects for building your PLC program, allowing their instantiation anywhere in the project. Support for inheritance means you can derive one functional block from another, extending its properties and methods and promoting code reuse. The result? Agility in development and maintenance, and the ability to create truly scalable projects.  <\/p>\n\n\n\n

Variables and editor features<\/strong> <\/h3>\n\n\n\n

The flexibility of MasterTool IEC XE extends beyond languages, offering an arsenal of advanced features to optimize programming. This includes special operators and variables<\/strong> that allow manipulation of scope operators for extended namespaces, function pointers (replacing INSTANCE_OF), Init and Exit methods for functional block lifecycle control, and the ability to use output variables in functions and method calls.  <\/p>\n\n\n\n

The software also supports permanent variables (VAR_TEMP, VAR_STAT, VAR_RETAIN, VAR_PERSISTENT), initialization of variables with arbitrary expressions, assignment as an expression, and index access with pointers and strings.    <\/p>\n\n\n\n

The editors<\/strong> are equipped with functionalities that enhance productivity: the ST Editor (Structured Text) offers line breaks, autocompletion, monitoring, and SET\/RESET assignment on the line. The FBD (Functional Block Diagram) and LD (Ladder Diagram) editors are reversible and programmable in a combined environment, allowing for changes to outputs in boxes with multiple outputs, branches and networks within networks, and flexibility in parameter updates. The SFC Editor (Sequential Function Chart) simplifies sequence creation with macros, multiple element selection, and automatic declaration of signaling variables.    <\/p>\n\n\n\n

For library management<\/strong>, MasterTool allows multiple versions in the same project via context, with installation in repositories, automatic updates, and debugging.    <\/p>\n\n\n\n

In addition, various additional functionalities<\/strong> enhance the experience: integrated PLC and task configuration in the device tree, UNICODE support, single-line comments, watchdog, multiple object selection, integrated online help, conditional compilation and breakpoints, and advanced debugging (step to cursor, return to previous caller). The software also ensures compatibility with IEC 61131-3 fieldbus drivers, symbolic and PLC configuration available in the application, free memory allocation for code and data, and pre-compilation notes on syntax errors. <\/p>\n\n\n\n

Simplified connection: Demystifying MQTT and Datalogger<\/strong> <\/h3>\n\n\n\n

Any automated industry requires highly efficient connectivity and data collection. MasterTool IEC XE was designed to make the use of interfaces for field networks incredibly simple, eliminating the need for specialized software to configure your field network; MasterTool meets this requirement with a single tool.  <\/p>\n\n\n\n

The MQTT protocol is a lightweight and open standard, ideal for M2M and IIoT environments where bandwidth is often limited. It operates on a publish\/subscribe model, an efficient alternative to the traditional client-server model. <\/p>\n\n\n\n

In this model, devices do not communicate directly. Instead, they connect to a central hub called a broker. When a device (the publisher) has data to send, it publishes it to a specific topic on the broker. Any other device (the subscriber) interested in this data simply subscribes to that topic and receives the relevant messages. This approach means that data is transmitted only when there is a change or at defined intervals, optimizing network traffic and ensuring real-time information. <\/p>\n\n\n\n

Parallel to connectivity, data collection and storage are crucial. Dataloggers can store data locally (on SD cards or controller RAM) or transmit it continuously to web-based tools. Integration with PLCs can be done through global IEC 61131-3 variables, with data transfer to \"data sinks\" (such as databases or CSV files). For high-speed applications or remote systems with intermittent connectivity, data can be buffered on the device and then logged. <\/p>\n\n\n\n
