5G+ new short distance to achieve the controller southbound clipping braid

The controller usually uses the fieldbus protocol to connect with I/O in a wired way. In recent years, more and more wireless demands and trends have appeared. The existing wireless technology has been unable to NTDI01 meet the harsh requirements of some new services and new scenarios on the network in terms of delay, reliability, synchronization accuracy and security, and how to achieve the southbound controller cliptail has been a difficult problem in the industry. Based on the new air interface design, Starflash short range communication technology is a new generation of wireless short range communication technology with low delay (less than 100us), multiple access (more than 256), high reliability (more than 99.999%), security, autonomy and controllability. Based on 5G+ new short distance, the southbound cliptail of the controller is implemented to realize the integration of the cellular network and the short-distance network of wide-area communication, which can not only further expand the coverage of the cellular network, open up the last 100 meters of the field connection, but also cooperate with the cellular network to realize the deterministic transmission with dual redundant characteristics, enhance the reliability of data transmission, and form a unique advantage.

5G+vPLC implements unified deployment of virtual PLC

NTDI01

5G+vPLC (Virtualization controller) relies on real-time virtualization technology, builds real-time computing environment on x86/ARM general hardware, and transforms traditional PLC into virtualized PLC control service through soft and hard decoupling. Virtualization PLC adopts domestic PLC software technology, meets the IEC-61131-3 standard, supports ST, LD, IL, SFC and CFC five programming languages, supports NTDI01 Modbus, CAN, EtherCAT, Profinet and other common industrial bus protocol virtualization access. Support industrial bus protocol and MQTT (message queue telemetry transmission) automatic conversion, PLC task maximum delay jitter <150us, to meet the needs of high-speed industrial control scenarios. At present, virtualization PLC integration and deployment have been completed on multiple models of 5G deterministic gateways such as EA1000 and DC2000.

Typical case

Case 1: Process industry – Steel company crane wireless remote control scenario

China Mobile cooperated with a steel enterprise to carry out automatic transformation of 14 cranes in its hot rolling mill. The 5G deterministic industrial gateway, as the northbound communication node of the PLC from the driving side station, realizes seamless redundant switching of the 2.6GHz and 4.9GHz dual-band networks of China Mobile’s 5G private network through multi-channel redundant deterministic transmission, significantly improves the on-site wireless transmission quality, reduces the packet loss rate by more than 50%, and the jitter is less than 10ms, and the control service has no cell handover jitter.
