Thanks to the internal storage capacity of more than 670 KByte, no external SDRAM is required, only a QSPI Flash for holding the protocol stack is needed, the performance is doubled in comparison to netX 50. For processing the fast I/Os, the application is provided with a second RISC CPU. It works in parallel to ARM and significantly relieves the demands made on the ARM software via short bus cycle times. Typical applications are IO-Link Master Gateways. The xPIC takes over the IO-Link data transfer, leaving the ARM completely available for processing the transmission protocol to the master.
Some Real-Time Ethernet systems use the CANopen object models or the same communication services such as EtherNet/IP and DeviceNet. This results in the task of connecting CAN as the „legacy“ network to the Real-Time Ethernet system. Up to now, that entailed using an expensive netX 100 controller, with its three communication channels. As an alternative, a dedicated CAN controller is now available. With this possibility, the netX 6 / 51 / 52 is so much more than just a Real-Time Ethernet interface chip equipped with a dual-port memory.
