Layout and function
As in the fail-safe SIMATIC controllers, the engineering is implemented with STEP 7 and the Distributed Safety option package. This means that existing know-how can continue to be used.
SIMATIC WinAC RTX F executes on all x86 hardware platforms with Windows XP Professional and is optimally matched to SIMATIC Industrial PCs. Especially when used on embedded PC platforms, such as the SIMATIC IPC 427C, the SIMATIC HMI IPC 477C or the SIMATIC S7-mEC with Windows Embedded Standard 2009, economical and extremely rugged solutions can be achieved. WinAC RTX F uses the main memory of the PC and offers a program backup in the data medium (e.g. HDD, CompactFlash card, SSD). Non-cyclic data, such as production parameters or recipe data, can be stored permanently on the data medium (e.g. HDD, CompactFlash card, SSD) of the PC with the help of system functions (SFC 82 - 84). In addition, all data can be held retentively in conjunction with an uninterruptible power supply (UPS).
Connection of the I/O
WinAC RTX F can control the distributed I/O not only via PROFIBUS, but also via PROFINET.
The I/O is connected via PROFIBUS DP at up to 12 Mbit/s via the integral DP interface of the SIMATIC IPCs or the embedded bundles. In addition, communications processors (CP 5611 A2/ 5613 A2) can also be used that support as many as four PROFIBUS lines with up to 500 slaves.
The connection to PROFINET is via Ethernet chipsets for PROFINET IO with RT:
Intel® Pro/1000 CT Gigabit Desktop
Intel® PRO/1000 PT dual port server adapter
or via a CP 1616 (PCI) or CP 1604 (PCI-104) communications processor.
The SIMATIC IPCs or the embedded bundles feature an optional integrated PROFINET interface, while it is standard for the S7-mEC RTX F.
In addition, WinAC RTX F also supports the system function isochronous mode. With isochronous mode, high-speed, time-dependent applications such as closed-loop controls can also be implemented with distributed I/O. This means that in addition to the control job other functions can be integrated into a PC or smaller, more economical PCs can be used for the same job.
With the new version WinAC RTX 2010 further PROFINET functions are available e.g. shared device, media redundancy and webserver functionality.
