Small local embedded PC integrates virtual PROFINET device

CX8093 Embedded PC with optional virtual device can be used as a 2-in-1 PROFINET device

The CX8093 Embedded PC from Beckhoff is equipped with a PROFINET RT device interface designed as a 2-port switch for daisy-chain cabling. A special characteristic is the added functionality of a virtual device which can be used to double the process data size or to connect a second controller.

Once the optional virtual device (slave interface) is activated, the CX8093 Embedded PC behaves like two PROFINET devices. 1000 bytes, i.e. the CX8093 can process twice the number of PROFINET process data.

An extra benefit of the virtual device is the ability to communicate with a second PROFINET controller, which is a simple way to increase system availability. On the one hand, the CX8093 (as a local controller) can verify the two incoming master signals by means of a plausibility check to monitor the function of the cabling, for example. On the other hand, failure of one of the masters can be detected and the second master can respond accordingly.

The space-saving CX8093 Embedded PC measures only 65 x 100 x 80 mm. In addition to Bus Terminals, EtherCAT Terminals can also be connected directly to the CX8093. During start-up, the CX8093 automatically detects which of these I/O systems is connected.

The dimension of the CX8093 Embedded PC just measures 65 x 100 x 80 mm It runs Windows CE 6.0 and features a 400 MHz ARM9 CPU, 64 MB RAM and a MicroSD card with up to 4 GB storage capacity. In addition to Bus Terminals, EtherCAT Terminals can also be connected directly to the CX8093. During start-up, the CX8093 automatically detects which of these I/O systems is connected.

Another special feature is a capacitive 1-second UPS that enables persistent data to be saved in the event of a supply voltage failure. The controller is programmed via the TwinCAT PLC automation software. The CX80xx series is also available for other bus systems such as Ethernet, EtherNet/IP, PROFIBUS, BACnet/IP, CANopen or OPC UA.
