The Motion Terminal VTEM is the world’s first standardised platform on the market, with valves controlled by Motion Apps. What does digitised pneumatics mean for you as an OEM or end user? You benefit from simpler engineering and ordering, faster commissioning and assembly, and more efficient and flexible operation – enabled by the intelligence of the integrated sensors, for example. The VTEM helps you to get your pneumatics system ready for Industry 4.0 with motion, pressure and flow control.
The advanced decentralised communication of the Motion Terminal expands the possibilities of pneumatics. It also becomes much easier to implement functions that would previously have required complex designs and time-consuming settings. The movements can be created with significant differences and also with new sequences. In addition, key parameters such as the travel time, pressure and flow rate can be checked via this communication and automatically corrected if necessary. The intelligence of the Motion Apps provides numerous options, for example for controlling and analysing related processes – including in networks.
The Motion Terminal functions are implemented using Motion Apps and integrated, flexible and programmable processors. This integrated intelligence makes the system much more flexible than wired hardware. You can now make adjustments decentrally within the system. You need significantly less bandwidth for the communication, while controlling and programming the entire system also become much less complex.
Disconnected: functions and hardware
The Motion Terminal is equipped with powerful processors. Thanks to this decentralised intelligence in the integrated controller [1] and the Motion Apps [2], the pneumatic functions are, for the first time, uncoupled from the mechanical hardware. You can easily assign these functions via apps. Plus, you now require just a single valve type for an extremely wide range of pneumatic movements.
Integrated sensors provide the valves in the Motion Terminal with intelligence. This new flexibility enables components such as cylinders to perform new tasks. Movements can be very individually modelled and adapted extremely efficiently to the relevant task. This brings significant performance gains for your production and generally reduces your costs, including if you are retrofitting systems.
A bridge circuit with integrated sensors that is made up of four proportionally controlled 2/2-way valves creates the smart actuator technology in the Motion Terminal. Piezo pilot and diaphragm poppet valves carry out the core tasks of independent pressurisation and exhaust. This means that you can realise a wide range of common valve functions in one valve, even proportional pressure regulation or complex control solutions such as Soft Stop.
Built-in sensors are indispensable in an intelligent, flexible system that is capable of learning. They can be used for adapting to changes in ambient conditions or system parameters such as fluctuations in supply pressure, or for reading out all the relevant information for big data processes.
The combination of integrated sensors [3] and the software-based, flexible adjustment of pressure and flow rate enable the system to carry out its own evaluations and adjustments. This not only saves you money, but also simplifies the entire system, from conceptualisation to modernisation. You therefore no longer need, for example, external load cells for condition monitoring during pressing procedures. Or you can reduce the cycle time by varying the process parameters, even within a stroke. You can then often also use smaller cylinders.
For certain tasks, data can be obtained in real time from external sensors via separately integrated inputs [4] that enable internal control. You can use this to develop optimised applications with pneumatics.
You can also use it to cost-effectively integrate intelligence and transparency into your tried-and-tested existing systems during modernisation – making retrofitting really worthwhile.
The Motion Terminal makes several communication channels with user interfaces available for you at the same time. Adjustment is quick and easy: directly via the Ethernet connection, your web browser, the intuitive WebConfig interface or the process data of a conventional machine control system. The simple function configuration offered by our Motion Apps will help you to speed up commissioning, reconfiguration and system adaptations. You can read out data via a transfer channel.
Open, global communication interfaces make the Festo Motion Terminal ready for future developments, such as software services and global networking. You can also use the OPC UA interface on the CPX-CEC to create a service-oriented architecture that is both platform and manufacturer-neutral – the ideal prerequisites for Industry 4.0.
At the same time, the CPX bus nodes [5] and the multitude of available I/O modules provide a tried-and-tested standard for communication in machine and production networks.
