September 11, 2008 – Beckhoff Automation released two new EtherCAT modules for fiber-optic cabling – the EK1501 EtherCAT Coupler and EK1521 junction terminal. With the fiber-optic EtherCAT modules, extremely long distance networking up to 2 km (1.24 miles) is now possible (100BASE-FX).The EtherCAT I/O Terminal system supports all common wiring topology methodologies: line, ring, tree and star. This flexibility is further enhanced with the ability to select different cable types.
Using the EK1501 EtherCAT Coupler and the EK1521 junction terminal, more flexible EtherCAT topologies are now possible through the use of glass fiber technology. Using standard Ethernet cabling (100BASE-TX), the maximum distance between two EtherCAT I/O stations is 100 m (328 feet). The EK1501 fiber-optic coupler connects EtherCAT to any number of EtherCAT I/O Terminals. The wiring connection is made via SC duplex sockets.
An additional fiber-optic module can be optionally connected via a second port; an additional switch is not required.The EK1501 EtherCAT Terminal with fiber-optic interface enables conversion of the EtherCAT protocol to multimode glass fiber technology within a terminal line. The combination of line and branches or stubs is particularly useful for flexible system wiring. The EtherCAT fiber-optic modules are ideal for widely distributed systems, such as wind farms or high tension systems. Even cable redundant systems with fiber-optic can be realized using the EtherCAT branch.
