S7-400 is the most powerful PLC in SIMATIC controller family. It can successfully implement fully integrated automation (TIA) solutions. S7-400 is a process engineering oriented system solution automation platform with modular design and high performance.
S7-400
Powerful PLC in the middle to high-end performance range
Solutions for demanding tasks
Comprehensive modules and CPUs of various performance levels can be optimally adjusted for specific automation tasks
It can realize distributed structure and is very flexible for application
Convenient connection
Optimal communication and networking capabilities
Easy operation, simple design, without fan
It can be expanded smoothly when tasks are added
Multiple calculations:
Multiple CPUs operate simultaneously in a S7-400 central device.
The multiple computing function can allocate the overall performance of S7-400. For example, complex technical tasks (such as open-loop control, computing, or communication) can be split and assigned to different CPUs. Each CPU can be assigned its own i/o.
modularization:
Through the powerful S7-400 backplane bus and the communication interface that can be directly connected to the CPU, the high-performance operation of many communication lines can be realized. For example, this can have a communication line for HMI and programming tasks, a communication line for high-performance isometric motion control components, and a "normal" i/o fieldbus. In addition, it can also realize the additional connection with mes/erp system or Internet.
Engineering configuration and diagnostics:
Combined with SIMATIC engineering configuration tool, S7-400 can be configured and programmed very efficiently, especially for a wide range of automation tasks using high-performance engineering components. For this purpose, high-level languages (such as SCL) and graphical configuration tools for sequence control systems, state diagrams and process diagrams can be used
S7-400H
Conformal coating (G3) is used as standard, which can enhance the resistance to environmental impact
High availability automation system with redundant design.
For applications with high fail safe requirements:
Processes that are costly to restart, costly to shut down, require little monitoring, and have few maintenance options.
Centralized function of redundant design
Improve i/o availability: switched i/o configuration
It can also be used as standard i/o: one side configuration
It can be used with the universal scalable SIMATIC et 200sp ha i/o system through step 7
Hot standby: in case of failure, it can automatically switch to the standby equipment.
Configuration with 2 separate racks or a separate central device
The switching i/o is connected through redundant PROFIBUS DP or system redundant PROFINET i/o.
S7-400F/FH
Fail safe automation system improves the safety requirements of the project
Meet the safety requirements of relevant standards (SIL 3 of IEC 61508, AK6 of DIN V 19250 and cat.4 of EN 954-1)
If necessary, fault tolerance can also be achieved through redundant design
No additional wiring required for safety i/o
Safety related communication via PROFIBUS DP using profisafe rules
Based on S7-400H with fail safe module and distributed et 200 i/o
The standard module can be used in non fail safe applications of automation systems
The isolation module is used to combine the fail safe module and the standard module in the safety mode of an ET 200m.
