Up to 60 percent more controller performance for ambitious automation tasks


Nuremberg, Nov 17, 2006 - Siemens Automation and Drives (A&D) have upgraded the performance of all the high-performance controllers in their Simatic S7-400 CPU product family and added new functions. Depending on the type, the new CPUs are 30 to 60 percent faster than their predecessors and feature higher communications performance as well as greater capacities than before. The Siemens high-performance controllers are especially useful in ambitious automation tasks in production and process automation.

Faster command run times for bit and word operations as well as fixed and floating-point arithmetic yield a cycle time 30 to 60 percent shorter than before. A new hardware architecture also enhances performance in communications services, especially in CPU types with an integrated Profinet interface. Thanks to a considerable increase in the number of data blocks (DB), function blocks (FB) and functions (FC), it is possible to implement even more extensive and complex applications. A uniform “block number band” has been implemented for the new CPUs so users can port their programs more easily within the S7-400 controller family.

Further functional expansions are available in firmware updates, resource controls and reset. A convenient and time-saving feature: new firmware versions can now be downloaded onto CPUs from a central location through bus systems via MPI (Multi-Point Interface), Profibus or Profinet. If there is a shortage of resources in the CPU despite the high capacities, programmers can now use the new SFC block (System Function Call) in their user programs to ensure a dynamic reaction to the shortage. The factory settings on the CPU can be restored easily at any time with the “Reset to Factory Settings” function.
