It was already possible to implement fieldbus master functionality with a CX8000 series Embedded C that has an integrated fieldbus slave in combination with an additional EtherCAT master terminal. With the CX8030 and CX8050 this function is now available for PROFIBUS or CANopen ̶ already integrated directly in compact Embedded PCs.
The CX8030 and CX8050 Embedded PCs are ideally suited to connect any fieldbus slave, from valve terminals to drives, in small to medium-sized machine applications. Furthermore, they can be used as gateways between EtherCAT slave devices as well as devices with a conventional slave interface such as PROFIBUS or CAN, as well as for coupling of machine controllers to a higher-level Ethernet infrastructure.
CX8030: In addition to normal data exchange, the PROFIBUS master also supports DPV1 communication. As a further feature, the master interface can also be configured as a slave interface if necessary. A simple PROFIBUS monitor for the CX8030 is available in the TwinCAT System Manager for diagnostic purposes.
CX8050: The CX8050 can operate as a CANopen master and also as a “simple” CAN master. In this case CAN 2.0A and CAN 2.0B are supported, i.e. 11-bit or 29-bit identifier. This means that all CAN applications and CAN devices that are commonly used can be addressed and networked with the CX8050. A simple CAN monitor is available for diagnostics.
The Embedded PCs measure just 65 x 100 x 80 mm and feature the Windows CE 6.0 operating system, a 400 MHz ARM9 CPU, 64 MB RAM and a 256 MB MicroSD card which can be extended to 4 GB. There is also an Ethernet 10/100 Mbit/s interface as well as a USB interface (behind the front flap). The PROFIBUS interface on the CX8030 is a 9-pin D-Sub plug with screening; the CANopen bus interface on the CX8050 is a 9-pin D-sub plug conforming to the CANopen specification with galvanic decoupling.
