Module Type Package (MTP)

TwinCAT for modular plant engineering

TwinCAT MTP: modular automation with Module Type Package

With modular automation, process technology plants can be flexibly implemented and adapted with little effort. Rigid automation systems that have been operated unchanged for years are increasingly becoming a thing of the past, with individuality and flexibility asserting themselves as the future of the process industry. The Module Type Package (MTP) is a concept that allows process technology plants to leverage maximum potential across the board, from the planning phase through to operation. This makes MTP a crucial component in the development of future modular automation solutions.

One of the emerging challenges for many sectors in the process industry, such as the pharmaceutical sector, is increasing fluctuation across sales markets. This is accompanied by the need for a shorter time-to-market due to accelerated development cycles. Product life cycles are shortened accordingly, and these in particular require economically profitable and simultaneously individualized production of small batches.

An increasingly popular solution is designing plants to be modular, which provides the option to reuse the modules for different purposes. This involves breaking down the plant’s entire process into individual sub-processes and mapping them using modules. Full plant modularity can then be achieved with a separate, decentralized controller for each module. The entire process can be remapped by subsequently integrating the individual modules into a higher-level control system (e.g., a DCS). As a result, the development work shifts from plant engineering to module engineering, enabling the plant to be flexibly modified with little effort, depending on current requirements. Additional modules can be added to the plant and modules that have already been integrated can be rearranged or removed. Complete reprogramming is not required, as most of the logic is in the individual modules. The higher-level controller only handles the orchestration of the modules and the services they offer, and is therefore referred to as the process orchestration layer (POL).

In practice, the concept is implemented by means of a manufacturer-independent standard for the description of process modules: the NAMUR Module Type Package (MTP). The MTP, which is defined in accordance with VDI/VDE/NAMUR 2658, contains all the information necessary to integrate a process module into a modular plant, including functions in the form of services, communication, and an HMI template. Interfaces defined in the MTP guideline enable plug-and-produce behavior, eliminating the work and costs associated with restructuring a plant. This means modules are only developed once and can then be integrated into plants independently of the controller manufacturer and POL.

TwinCAT MTP functionality in detail

The Module Type Package (MTP) concept is integrated into TwinCAT via TwinCAT MTP Runtime and TwinCAT MTP Engineering. TwinCAT Engineering includes a project management system that TwinCAT MTP Engineering is integrated into as its own project type. The project type enables the generic definition of a module, and the MTP file can be generated based on this before programming. Existing information can be processed via an open API, an MTP import, or a DEXPI import. In addition, the information can be used for automated PLC and HMI generation.

Subsequent changes in MTP project management are integrated by means of automatic project synchronization. Only the actual process logic of the functionalities being offered needs to be programmed in the prepared state machine.

Finally, the project can be activated, which automatically makes the variables of the defined interfaces available to the POL via OPC UA.

The following interactive graphic explains the process from the development of the module with TwinCAT MTP to its integration into the plant in individual steps. Then, application scenarios for TwinCAT MTP at the various levels of a process technology system are illustrated with short videos.

Specifically, this video shows how modularity can be implemented within the module using functional units in the greenfield. These functional units are designed dynamically so that they can be integrated flexibly, allowing the module to be customized for the current application.

In this use case, Ajinomoto Omnichem (an Ajinomoto Group company) and Beckhoff successfully demonstrated how the Module Type Package concept can be used to automate an industrial plant.

A special feature of the plant shown is the use of the MTP hub. In this application, all modules of the plant were implemented on a central Beckhoff control system. The PC-based control technology makes it possible to implement the modules in independent PLC programs and make them available to the POL separately. Through this architecture, the plant structure can be changed without having to adapt the control system – it automatically recognizes which modules are currently connected. The plug-and-produce behavior of the MTP concept enables simple reconfiguration in the POL, which has reduced the changeover time considerably.

FAQs, further information, and contact

TwinCAT allows for straightforward MTP programming without requiring in-depth knowledge of the relevant guidelines: It starts with the definition of the MTP interface, which results in the MTP file. This is then used for automatic code generation for the PLC and the HMI, allowing developers to concentrate primarily on the actual process logic and leave a large part of the programming to TwinCAT.

No, this is not necessary with PC-based control technology. It is also possible to run several MTP modules simultaneously on high-performance Beckhoff Industrial PCs. The resulting MTP hub makes the individual modules available to the control level independently of each other.

Yes, this is possible due to the integrated engineering features in TwinCAT. In addition to the MTP import, it is also possible to read the DEXPI format or proprietary data sources into TwinCAT. This means information from upstream planning steps can be used directly in the engineering environment and passed on to the control level.
