PLC - S7- 400

  •     The power PLC for the mid to high-end performance ranges.     
  •     The solution for even the most demanding tasks.
  •     With a comprehensive range of modules and performancegraded CPUs for optimal adaptation to the automation task.
  •     Flexible in use through simple implementation of distributed structures; user-friendly connections.
  •     Optimal communication and networking options.
  •     User-friendly handling and uncomplicated design without a fan.
  •     Can be expanded without problems when the tasks increase.
  •     Multicomputing: Simultaneous operation of several CPUs in one S7-400 central controller. Multicomputing distributes the overall performance power of an S7-400. For example, complex tasks can be divided into technologies such as open-loop control, computing or communication, and assigned to different CPUs. And every CPU can be assigned its own local I/O.
  •     Modularity: The powerful backplane bus of the S7-400 and the communication interfaces that can be connected direct to the CPU enable high-performance operation of a host of communication lines. This enables, for example, division into one communication path for HMI and programming tasks, one for high-performance and equidistant motion control components, and one for a "normal" I/O fieldbus. Additionally required connections to MES/ERP systems or the Internet can also be implemented.
  •     Engineering and diagnostics: The S7-400 is configured and programmed extremely efficiently together with the SIMATIC Engineering Tools particularly in the case of extensive automation solutions with a high engineering component. For this purpose, high-level languages such as SCL and graphical engineering tools for sequential controls, state graph programs and technology-oriented diagrams are available, for exampl


  •     Fault-tolerant automation system with redundant design.     
  •     For applications with high fail-safety requirements. Processes with high restart costs, expensive downtimes, little supervision, and few maintenance options.
  •     Redundant central functions.
  •     Increases availability of I/O: switched I/O configuration.
  •     Also possible to use I/Os with standard availability: singlesided configuration.
  •     Hot stand-by: automatic reaction-free switching to the standby unit in the event of a fault.
  •     Configuration with two separate or one divided central rack.
  •     Connection of switched I/O via redundant PROFIBUS DP


  •     Failsafe automation system for plants with increased safety requirements     
  •     Complies with safety requirements to SIL 3 in accordance with IEC 61508, AK6 in accordance with DIN V 19250 and Cat. 4 in accordance with EN 954-1
  •     If required, also fault tolerant through redundant design
  •     Without additional wiring of the safety-related I/O:
  •     Safety-relevant communication via PROFIBUS DP with PROFIsafe profile
  •     Based on S7-400H and ET 200M with fail-safe modules
  •     Standard modules for non-safety-related applications can also be used in the automation system
  •     Isolation module for joint use of fail-safe and standard modules in safety mode in one ET 200M
