Maximum effi ciency for machine builders, control cabinet manufacturers and end users
P
PMA The MX-System from Beckhoff is a fl exible, space- optimised, intelligent solution that can completely replace
conventional control cabinets, thereby opening up entirely new possibilities in plant automation. As a modular control cabinet replacement that can also be decentralised if required, the MX-System saves engineering, assembly, installation and maintenance eff ort.
The basic concept of the MX-System is to standardise the electrical and mechanical interfaces for all electronic and electromechanical components, resulting in two interfaces: • A data interface that integrates each functional unit into an EtherCAT network, supplying it with 24VDC or 48VDC, if required. • A second interface has been defi ned as
standard for the low-voltage range. These interfaces distribute the mains voltage of up to 530VAC and DC voltage of up to 848V for the drive system. The standardisation allows all functionality traditionally found in a control cabinet to be mapped as a backplane system. Analogous to the interfaces, there are two diff erent backplane types, which have the described interfaces in the form of connectors as essential features. The backplanes feature robust aluminum housings. The combination of backplane and housing is called a baseplate. In addition, there is a full range of function

modules from the IPCs, bus couplers, I/O, motion, relays and system power supply, that can be simply plugged in and screwed onto the baseplate.
The combination of a baseplate and function modules results in an IP67- protected automation system that is space optimise and directly mounted on the machine.
System advantages
One particular advantage is that the MX-System function modules integrate individual functions, such as line protection for outgoing lines. This facilitates project planning and signifi cantly reduces the number of components. Also, the number of pages in circuit diagrams and parts lists is reduced by up to 80%.
Even in the engineering phase, the low installation space requirement of the MX- System creates further advantages because this facilitates simpler coordination between departments, as there is usually no need to design special installation spaces and brackets for the MX-System.
Another important aspect is that the MX- System meets the requirements of relevant control cabinet standards and, in contrast to conventional control cabinets, it is also IEC-, UL- and CSA-compliant, making it a globally standardised solution. Thanks to its ease of connecting it to a baseplate, the MX-System can be set up within an hour.
The MX-System can be integrated

visually and functionally into the machine installation space due to its considerable compactness, signifi cantly reducing the machine footprint. Modular machine concepts can be realised by cascading MX-System setups. Then there are the signifi cantly shorter cable runs to the sensors and actuators. Using pre-assembled cables shortens the installation time and provides a high level of protection against errors during cable connection. For the machine end user, key advantages include service and maintenance: the MX- System consists of EtherCAT components that are networked throughout, so comprehensive system diagnostics are possible at any time. In addition to classic status LEDs, each function module has a unique serial number in the form of a DataMatrix code, scannable via a smartphone app; the modules are hot- swappable.
Operators also benefi t from the fact that the modular MX-System covers the complete variety of automation technology with considerably fewer parts and therefore fewer assemblies to stock as spares. Through their simple basic principle, MX- System modules can also be reused very easily beyond the life of the machine.
