Real-Time Ethernet

The CX8090 supports the Real-Time Ethernet protocol from Beckhoff as a master with its Real-Time Ethernet interface (X101/102). This means that the BK9xx0 bus couplers on the CX8090 can be operated as decentralized nodes. In principle there is no restriction on the number of bus couplers that can be connected to a CX8090; however, it is recommended to limit this to 3 nodes.

If you now switch the CX8090 to Config Mode you can scan for RT-Ethernet-capable devices. Naturally you can also append the bus couplers manually.

RT-Ethernet protocol and EAP protocol

Instead of the RT-Ethernet protocol, also the EAP protocol can be operated. Simultaneous operation of both protocols is in preparation. Pay attention here to the task times used and adjust them according to the system load.
