CX8090 | Embedded PC with Ethernet
The CX8090 is a control system with a switched Ethernet port. It supports protocols such as real-time Ethernet, ADS UDP/TCP,
Modbus TCP client/server or open TCP/IP-UDP/IP communication. K-bus or E-bus terminals can be attached as required; the CX8090
automatically recognises the type of I/O system connected during the start-up phase. The control system is programmed with
TwinCAT via the fieldbus interface or the additional Ethernet interface.
