Siemens develop a new redundant control system

Reduce the possibility of failure or unexpected downtime as much as possible to increase factory efficiency and have become the main demand for production enterprises. To this end, Siemens developed a new SIMATIC S7-1500 R / H series redundant control system. Based on the standard SIMATIC S7-1500 CPU, SIMATIC S7-1500 R / H uses transparent programming methods, using the TIA Portal STEP 7 programming language to program, migrate the program from standard systems to redundant systems without additional work. SIMATIC S7-1500 R / H can effectively prevent data loss and avoid downtime. In addition, the series control system uses the PROFINET system redundant manner to take advantage of the efficient, flexible, high performance characteristics of PROFINET. Published at the work The new SIMATIC S7-1500 redundant controller covers three CPUs, which are CPU1513R, CPU1515R, and CPU 1517h. Among them, CPU1513R and CPU1515R are suitable for small and medium-sized project applications. If a CPU fails, the alternate CPU will automatically take over the program, and the program can quickly recover run to prevent data loss. In addition, the communication method based on the PROFINET system redundancy can also improve the availability of the device. Field devices (eg, ET 200SP / MP) supporting the PROFINET S2 redundant feature (e.g., ET 200SP / MP) Connect to redundant CPUs via PROFINET, which constitutes a PROFINET redundant communication, even if the network is interrupted, field devices can continue to work. The CPU 1517H performance with similar functional characteristics is stronger, suitable for large project applications. This series of CPUs with specialized fiber synchronous modules that achieve fast and smooth switching. In the future, the CPU 1517h will also develop the PROFINET redundant network. SIMATIC S7-1500 R / H can minimize the production of faults. For example, in the fields of production, energy, water supply systems, environmental monitoring systems, airport navigation lighting, grouping station systems, etc., can effectively avoid downtime caused by controller faults; in the fields of baggage processing, elevated warehouses, tracking and traceability can be avoided High restart costs caused by data loss due to factory failures; in the fields of sewage treatment plants, tunnels, ship locks, building systems, even if there is no supervision and maintenance personnel, it can guarantee normal operation. Siemens SIMATIC Series Programmable Logic Controller (PLC) was born in 1958. After 60 years of development and innovation, from the earliest S3 series to today's S7 series, it has become a wide range of programmable controllers for global industrial applications. , Read the full article, original text title: New product | Siemens new SIMATIC S7-1500 redundant controller is coming Article Source: [Micro Signal: Gkongnews, WeChat public number: Industrial Control Headline] Welcome to add attention!
