Product Description:

For industrial automation, the Beckhoff EK1110 EtherCAT Coupler is essential since it extends EtherCAT networks. This is accomplished by this little gadget, which weighs around 50 grams, translating E-bus signals to the popular 100BASE-TX Ethernet standard. The smooth integration of several devices and network components made possible by this conversion process promotes effective data interchange and control. Support for fast data transmission rates of up to 100 Mbit/s is the core feature of the EK1110. For accurate industrial process management and monitoring, this feature guarantees real-time communication between various automation system components. The one µs delay of the coupler reduces transmission latency, which improves performance even further. For applications that need quick action, such as motion control and safety systems, this quick reaction time is essential.

Reliable performance in challenging industrial situations is ensured by the sturdy architecture of the EK1110. Complying with EN 61000-6-2/EN 61000-6-4 standards ensures immunity to electromagnetic interference, while its IP20 protection grade protects the device from dust and other solid particles. Additionally, the coupler's vibration and shock resistance, which meet EN 60068-2-6/EN 60068-2-27 criteria, guarantees its lifespan and durability even in the face of challenging working circumstances. The ability of the EK1110 to send data using shielded Ethernet/EtherCAT cables, which enable lengths of up to 100 meters between stations, increases its operating flexibility. This increased range makes more flexibility in network architecture and deployment possible. Furthermore, a variety of devices and systems may be seamlessly integrated with the coupler since it is compatible with any EtherCAT protocol. The EK1110's adaptability makes it a useful tool for a variety of industrial automation applications.

It is simple to integrate the EK1110 into a variety of industrial configurations due to its small size and adjustable installation location. Reliable performance in a range of conditions is ensured by its operating temperature range of -25°C to +60°C. Because the gadget is powered directly from the E-bus and typically consumes 130 mA of current, integrating it into current systems is made easier. Additionally, the EK1110's safety and adherence to international standards are shown by its CE, UL, ATEX, and IECEx certifications. Customers may feel even more secure knowing Wake Industrial offers a one-year guarantee on this dependable and effective EtherCAT coupler.

What you see (LED / behaviour) What it means Quick corrective check
DC LED off – all LEDs dark No 24 V on the power contacts Measure the supply; replace the cabinet fuse or tighten the spring-clamp plug 
RUN LED off + ERR LED red immediately after power-up Coupler HW self-test failed (state = INIT) Power-cycle ≥ 10 s; if it repeats, the module is defective 
RUN LED flashes 2 Hz green and never turns solid Device stuck in PRE-OP – master did not download the configuration In TwinCAT/TIA activate the terminal map and restart the bus 
RUN LED flashes 1 Hz green Device in SAFE-OP – PDO size/order mismatch Compare EL-terminal order with PLC project, correct and reboot 
ERR LED single-flash red Invalid EEPROM / firmware CRC Re-flash the latest EK1110 firmware with the Beckhoff Update Tool 
ERR LED double-flash red “Slave not present” – the coupler isn’t seen by the master Check that the address is scanned, verify topology, correct if missing 
ERR LED red, master shows “link error” Physical link lost on RJ-45 Swap the Ethernet cable, clean the RJ-45, verify 100 Mb link status 
ERR LED shows “missing link” code Down-stream port has no cable or bad shield Check the spur cable, ensure < 100 m Cat-5e and proper shielding 
RUN green but process data frozen New EL-terminal was hot-plugged but not scanned Run “Scan for Changes” (TwinCAT) or reboot the EtherCAT line 
Coupler resets when cabinet > 55 °C Over-temperature derating Improve airflow; leave ≥ 30 mm above the unit; keep ambient ≤ 55 °C
