Alizem is now very proud member of the EtherCAT technology group.

What is EtherCAT technology ?

"The EtherCAT technology overcomes the system limitations of other Ethernet solutions: The Ethernet packet is no longer received, then interpreted and copied as process data at every connection. Instead, the Ethernet frame is processed on the fly: the newly developed FMMU (fieldbus memory management unit) in each slave node reads the data addressed to it, while the telegram is forwarded to the next device. Similarly, input data is inserted while the telegram passes through. The telegrams are only delayed by a few nanoseconds.

On the master side, very inexpensive, commercially available standard network interface cards (NIC) or any on board Ethernet controller can be as hardware interface. The common feature of these interfaces is data transfer to the PC via DMA (direct memory access), i.e. no CPU capacity is taken up for the network access." (Source: EtherCAT TG)
