Standardized interfaces

Each function module is connected to EtherCAT via the data backplane.
Each function module is connected to EtherCAT via the data backplane.

The core of each baseplate in the MX-System is formed by the backplanes installed in it, which provide the required power voltages (via power backplane) and the control voltages, communication and diagnostic functions (via data backplane) via standardized connectors. The data stored on the EtherCAT ASICs integrated in the data backplane connect each data slot to EtherCAT and enable the hot swap functionality and real-time capability of the MX-System. Protective extra-low voltages of 24 V DC or 48 V DC and a maximum current of 30 A are also routed to all data connectors via the data backplane. A module can be supplied with current of max. 20 A via a data connector. The power backplane distributes power voltages of 400 to 480 V AC and 600 V DC at a maximum current of 63 A among all power connectors, and one power connector can supply up to 35 A to a function module.

Each function module uses a data slot, which allows it to be fully parameterized and diagnosed as an EtherCAT device, power modules additionally use a power slot. In terms of circuitry, the data and power slots completely replace the previously necessary wiring of the individual components.

The connectors developed for the MX-System are designed to provide IP20 contact protection, even when no modules and no covers have been mounted on the slots. This also applies to the connectors of the modules.

Housekeeping acquires data on temperature, shock, vibration, barometric pressure and humidity, and enables dew point monitoring, among other features, enabling safe power-up even in critical ambient conditions. Housekeeping data as well as module-specific and application-specific diagnostic data and parameters can be made available to the machine end user directly on a smartphone via Bluetooth.
