Slice-based I/O and control system

There are many different I/O slice systems. With the X20 system, B&R is setting new standards according to the motto "Perfection in Automation". Born from experience gained from applications all over the world, numerous conversations with customers and with the aim for easier, more economical and secure usage, the X20 system is a new universal solution for any automated task in machine and system manufacturing.

    from standard applications up to the highest performance class

    The optimally scaled X20 system CPU line satisfies a wide range of needs. It can be implemented anywhere, from standard applications to the most demanding applications with the highest performance requirements. It can even master cycle times of 100 µs.

    At B&R, RS232, Ethernet and USB are already standard equipment. Network capability and connecting USB devices are therefore possible at no additional cost. In addition, every CPU has a POWERLINK connection for real-time communication. The possibility to directly connect axes is already integrated. Although the standard features of the CPUs can handle the majority of applications, there are also up to three multipurpose slots for additional interface modules.

    Because the X20 CPU was designed for mounting rail installation in a control cabinet, up to 250 X20 I/O modules - 3000 channels - can be connected directly. This provides the highest performance as well as the advantages of the remote backplane.

    A power supply integrated in the CPU with I/O supply terminals provides power for the backplane and I/O sensors and actuators, eliminating the need for additional system components. With a direct I/O connection to an X20 CPU, you get all the advantages of the remote backplane, i.e. the ability to repeatedly place I/O line sections anywhere within 100 m using a cable or to add modules with IP67 protection.

    extremely compact, surprisingly powerful

    With a width of 37.5 mm the X20 Compact CPUs are extremely compact, yet surprisingly powerful. Less powerful than the PC-based CPUs, there are several models of Compact CPUs available in 2 performance classes.

    The Compact CPUs are ideal for situations where cycle times in the millisecond range are acceptable and value is the deciding factor. A range of models with CAN and Ethernet can adapt optimally to all demands. The result: extremely sleek automation solutions.

    The Compact CPU's design and dimensions correspond to the X20 System. The X20 I/O modules are connected directly to the CPU. These are attached seamlessly to the CPU, making the entire system an extreme space-saver in the control cabinet. Despite the sleek profile, the CPU supply, the X2X Link supply, and the I/O module supply are integrated in the system. No additional power modules are necessary.

    All CPUs have at least two things in common: multitasking capability and programming with B&R Automation Studio using all relevant IEC61131-3 languages and C.

    with integrated fieldbus connection

    Remote design of I/O systems is one of the standard topologies used in automation solutions for machines and equipment. In addition, fieldbuses with bus controllers are normally used. Larger topologies or standard fieldbuses like CANopen, PROFIBUS DP, or DeviceNet can cause relatively long response times.

    An input must travel via the bus controller to the CPU before it is processed. The output data must then return on the same path. This is sufficient for most I/O functions. However, this response time is too long for some functions. The best solution is for the bus controller to process the data. This type of data preprocessing is usually associated with limited CPU function in the programmable bus controller.

    Fieldbus CPUs with integrated fieldbus connections overcome these limitations. Fieldbus CPUs are variations of Compact CPUs. In addition to these features, there is also the option of connecting fieldbus modules to the left side. The full CPU function of the Compact CPUs plus a plug-in fieldbus module create many more possibilities than simply data preprocessing. There are enough reserves for relatively complex application processing. Intelligent substations are another area of use. That means a part of the machine part must continue to function, even when separated from the main controller.

    Based on the Compact CPU platform with up to 2 plug-in interface modules for the respective fieldbus connection, this results in a very compact (62.5 mm and 87.5 mm), powerful and intelligent fieldbus controller.
