![]() ![]() Allowing sub dissectors to handle data based on heuristic analysis is always enabled and cannot be turned off. There are no EtherCAT specific preference settings. = Round trip: Frame is not circulating (0)Ġ. Length : 100 (0圆4) - No Roundtrip - Last Sub Command = Type: EtherCAT command (0x0001)ĮtherCAT datagram(s): 'LRW': Len: 100, Adp 0x0, Ado 0x1, Wc 2ĮtherCAT datagram: Cmd: 'LRW' (12), Len: 100, Addr 0x10000, Cnt 2Ĭommand : Logical memory read write (0x0c) The assigned UDP port for EtherCAT is 0x88a4.Įxample traffic Frame 1 (128 bytes on wire, 128 bytes captured)Įthernet II, Src: MS-NLB-PhysServer-14_a6:c9:01:8e (02:0e:a6:c9:01:8e), Dst: Broadcast (ff:ff:ff:ff:ff:ff) UDP: EtherCAT protocol can be transported in UDP datagrams. The assigned Ethernet type for EtherCAT traffic is 0x88A4. History Protocol dependenciesĮthernet: EtherCAT can use Ethernet as its transport mechanism. ![]() This also enables any control with Ethernet protocol stack to address EtherCAT systems. If IP routing is required, the EtherCAT protocol can be inserted into UDP/IP or TCP/IP datagrams. Broadcast, multicast and communication between slaves are possible. The data sequence is independent of the physical order of the nodes in the network addressing can be in any order. ![]() It may consist of several sub-datagrams, each serving a particular memory area of the logical process images that can be up to 4 gigabytes in size. The EtherCAT protocol is optimised for process data and is transported directly within the standard IEEE 802.3 Ethernet frame using Ethertype 0x88a4. ![]() The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs. EtherCAT is an open, high performance Ethernet-based fieldbus system. ![]()
