February 23, 2012 -- Siemens Industry added a PROFINET interface with a 2-port switch to its line of fault-tolerant Simatic S7 400H high performance controllers. This addition enhances the unique I/O system redundancy and availability provided by the controllers. The product line, that now includes the new 416-5H model, has also been improved with a larger memory and an expanded quantity structure for data and function block as well as function calls. The PROFINET interface with a 2-port switch is used for plant communication and supports fault tolerant H-connections via TCP/IP (ISO on TCP). Similar to the integrated MPI/DP and PROFIBUS DP interfaces, the interface permits the system-redundant connection of IO devices.
Using fiber-optic cables, data synchronization between controllers is possible at distances of up to 10 kilometers. The portfolio now includes a new 416-5H controller with 16 MB RAM, together with the innovated 412-5H CPU with 1 MB, 414-5H with 4 MB, and the 417-5H with 32 MB RAM. The controllers are programmed and configured using the Simatic Step 7 engineering tool.
