Software controller

Safety-related tasks can now be performed via PC using the Siemens fail-safe software controller for PC-based automation, Simatic WinAC RTX F, a Windows XP or eXP-based controller with an optimised runtime system to process extensive PC applications simultaneously.

As with the modular Simatic S7 controllers, the user employs Step 7 as engineering software, supplemented by the distributed safety option package for safety-related applications.

The package is particularly suitable for high-performance tasks with substantial data volumes and simultaneous, demanding real-time requirements. The latest technology, such as dual-core processors, optimise use, for example, with one core for Windows applications and the other for Simatic WinAC RTX F.

This fail-safe software controller meets the relevant safety requirements and applicable standards EN 954-1 up to Cat.4, IEC 62061 up to SIL 3, and EN ISO 13849-1 up to PL e. It can be installed on all current x86 PC hardware platforms, for example, on all Simatic PCs.

There are pre-installed versions including the Simatic S7-mEC-RTX F fail-safe modular embedded controller in Simatic S7-300 design, and the embedded fail-safe Simatic IPC427C-RTX F rail-mounted PC.

The controller can be expanded using the safety-oriented peripherals ET 200S, ET 200M and ETpro with IP67 degree of protection, or with the safety-oriented ET 200eco block I/O with IP67 degree of protection.
