CX8000 is a device family of programmable controllers with a 32 bit ARM-based CPU, which can be used for the processing of PLC programs or as slave devices for higher-level fieldbus systems. Unlike the non-programmable Bus Couplers of the EK series (EtherCAT Koppler [German for EtherCAT Coupler]), which only act as gateway between the associated fieldbus system and the connected EtherCAT Terminals, the CX8000 is programmable and able to run its own control program.
Like all CX products, the CX8000 devices are programmed and commissioned via the Ethernet interface, which can, of course, also be used for the connection of the control system with a regular network. Some Embedded PCs have additional Ethernet interfaces with switch functionality, so that a linear “daisy chain” topology can be established cost-effectively without additional hardware. The other connections on the lower plug level are fieldbus-specific. A replaceable coin cell for date and time, a number of dip switches for setting function modes, a slot for microSD flash memory cards and a USB port type B can be found under the front flap at the upper housing level. Thanks to their low electrical power consumption, the units are fanless.
All software required for operating the device, including the operating system, the TwinCAT files and user files and data, is stored on the microSD Flash card. This means the unit is easy to replace if necessary. Commercial card readers can be used to access the card data. The size of the microSD Flash card (e.g. 256 MB) can be chosen depending on the application and the quantity of data to be stored.
The CX8000 device family features an integrated, capacitive 1-second UPS, which in the event of a failure of the supply voltage provides sufficient energy for saving remanent data. Important data are thus preserved in a non-volatile manner without battery backup.
With a high-performance but nevertheless energy-saving 32 bit ARM processor, EtherCAT as I/O bus and TwinCAT PLC with extensive PLC libraries, the Embedded Controllers from the CX8000 series represent high-performance and versatile controllers with slave fieldbus connection.
