![]() ![]() Parallel processing throughout segments enables significantly reduced propagation delay times.integration of 100 Mbit/s devices and segments within EtherCAT G networks.Now, large-scale systems can be synchronized and operated using a single, central master. The new branch model was developed to address growing demand for ever shorter cycle times in increasingly extensive systems integrating large numbers of devices. With EtherCAT G, applications and systems like these can be supported with a single EtherCAT G master while at the same time incorporating other automation equipment or drives. This, along with short cycle times of ≤ 1 millisecond, calls for high data bandwidths. Machine vision, condition monitoring and highly innovative transport systems like the eXtended Transport System (XTS) and XPlanar all rely on the ability to transmit several hundred bytes of process data per device and cycle. The exceptional performance of EtherCAT has succeeded in satisfying user requirements of almost every kind across countless industry sectors and applications – in everything from highly dynamic machine tools and complex packaging systems through to logistics centers. High performance, high complexity – 100 servo axes every 30 μs, 2,000 digital inputs/outputs every 15 μs synchronization accuracy better than 100 ns.And the built-in system of distributed clocks still ensures devices are synchronized precisely in better than 100 ns. Network-wide diagnostics are available to help minimize machine downtime and increase availability. Optional machine modules can still be plugged and unplugged via the Hot Connect feature. Devices with three or four ports (junctions) enable users to flexibly configure network topologies that suit the exact requirements of their machine architecture. The last device in a segmentor stub line identifies an open port and utilizes the full duplex feature of Ethernet network physics to send the telegram back to the master.ĮtherCAT G and EtherCAT G10 also retain all other capabilities of EtherCAT. Hardware propagation times are the only factor delaying telegram processing. Each EtherCAT slave still reads the data addressed to it “on the fly” and inserts its own data into the frame as the frame moves downstream now, though, it does this at 1 Gbit/s or 10 Gbit/s. As before, the devices on a network receive the telegrams sent by the EtherCAT master. ![]() The EtherCAT protocol itself remains unchanged. Telegram processing on the fly at 100 Mbit/s, 1 Gbit/s and 10 Gbit/sĮtherCAT G builds on the principles of the successful EtherCAT technology but moves the available data rates up to 1 Gbit/s and 10 Gbit/s.
