A new firmware, with Profinet functions such as isochronous mode, I Device, Shared Device and Media Redundancy Protocol, and an integrated web server expand the functionality and application fields of the controllers significantly. In addition, the S7-400 controller family has been supplemented by the new CPU 412-2 PN/DP for the lower performance segment. On the Simatic S7-300 the working memory and performance of the CPU 319-3 PN/DP have been increased.

The upgraded CPU 319-3 PN/DP of the Simatic S7-300 controllers now has considerably more working memory and performance than its predecessor version. Equipped with two Profinet ports and a working memory of 2 megabytes (2.5 megabytes in the fail-safe version), the CPU now achieves a bit processing time of four nanoseconds, i.e. a computing speed that is two and a half times faster. The new CPU 412-2 PN/DP for the Simatic S7-400 controllers is provided with a variety of communication functions and is designed for the lower performance segment. Furthermore, the working memory capacity of the CPUs 414 and 416 has been increased.

The new firmware V 3.2 for the S7-300 controllers and V 6.0 for S7-400 controllers provide enhanced options in system design and simplified maintenance and diagnostics functions. The firmware incorporates the Profinet functions isochronous mode, I Device, Shared Device and Media Redundancy Protocol, as well as a web server with user-definable web pages. The new firmware is available for the Profinet controllers CPU 319-3 PN/DP, 315/317-2 PN/DP and their fail-safe variants CPU 315F-2 PN/DP and CPU 317F-2 PN/DP, as well as for the new S7-400 controllers CPU 412-2 PN/DP and the CPUs 414/416-3 PN/DP.
