application

■ Avoid downtime caused by controller failure. Mainly used in production, energy, water supply system, airport navigation lighting, marshalling station system and other fields.

■ Avoid high restart costs caused by data loss due to factory failures. Mainly used in areas such as baggage handling, high-bay warehouse, tracking and tracing.

■ Protect the plant, workpieces and materials when the plant or machine is down. Mainly used in furnaces, semiconductors, ships and other fields.

■ Unsupervised and maintenance personnel can also guarantee normal operation. Mainly used in sewage treatment plants, tunnels, ship locks, building systems and other fields. To the top of the page

benefit

Simple and efficient engineering configuration

  As in the standard system, SIMATIC S7-400H can be programmed in all STEP 7 programming languages. It is easy to migrate the program from the standard system to the redundant system, and vice versa. When the program is loaded, it is automatically transferred to the two redundant controllers. With STEP 7, you can set parameters for specific redundant functions and configurations.

Excellent diagnosis and module replacement advantages

■ Utilizing the integrated self-diagnosis function, the system can detect faults and send signals in advance to avoid the impact of faults on the production process. In this way, faulty components can be replaced in a targeted manner and the repair process can be speeded up.

■ All components can be hot-plugged during system operation. After replacing a CPU, all current programs and data can be automatically reloaded.

■ Even when the system is running, you can modify the program (for example, modification and reloading of program blocks), change the configuration (for example, add or delete DP slaves or modules), and change the memory allocation of the CPU. To the top of the page

Design and function

According to statistics, all automation components (whether mechanical, electromechanical, or electronic) will fail. Therefore, plant maintenance and plant transformation are indispensable. In practical applications, it is unrealistic to expect 100% availability.

Through Siemens SIMATIC S7-400H, the probability of production failure can be reduced to a greater extent, and the productivity can be maximized.

  SIMATIC S7-400H has the following functions:

  ■ In the event of a failure, it can switch without disturbance

  ■ Integrated fault detection function; detect faults in advance to avoid affecting the production process

  ■ Online maintenance, you can replace faulty components during plant operation

  ■ Configuration changes, you can expand the capacity of the factory during the operation of the factory

  ■ Automatic event synchronization

  ■ High-availability communication

  ■ Redundant connection of I/O devices
