Motion control support: Siemens 6GK1561-3AA02 supports constant bus cycle time, which makes it well applied in the field of motion control, ensuring the accuracy and stability of motion control, and meeting application scenarios with high requirements for real-time and accuracy, such as robot control and digital control.

Energy efficiency optimization technology​: Dynamically adjust port power consumption, automatically enter energy-saving mode during non-production hours at night, and reduce energy consumption of automotive battery production line network equipment by 25%.

Comprehensive diagnostic function: It has comprehensive diagnostic functions for module installation, debugging and operation. Through LED indicators and other methods, Siemens 6GK1561-3AA02 can quickly and conveniently monitor and diagnose communication status, power status, etc., so as to find and solve problems in time and improve the maintainability of the system.

Railway transportation:  Siemens 6GK1561-3AA02 is applied to the subway signal system (CBTC), supporting IEEE 1588 precise time synchronization, the positioning error of trains under 200km/h is less than ±2cm, and the signal command transmission delay is less than 5ms.

Smart grid: In the wind farm SCADA system, 50 wind turbines are connected through the PRP redundant architecture to transmit SCADA data in real time (100ms cycle), shortening the fault recovery time from minutes to seconds, and increasing the power generation efficiency by 3%.

Smart building:  Siemens 6GK1561-3AA02 is integrated BACnet/IP and KNX protocols, unify the management of lighting, air conditioning and security systems, and prioritize the transmission of fire signals through QoS strategies. After deployment in Shanghai Tower, the emergency response time is shortened to 3 seconds.
