Fail-safe software controller

The Simatic WinAC RTX fail-safe software controller for PC-based automation allows safety-related tasks to be performed via PC.

Simatic WinAC RTX F is a Windows XP or eXP-based controller with an optimised run time 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.

Simatic WinAC RTX F is suitable for high-performance tasks with substantial data volumes and simultaneous, demanding real-time requirements. The latest technology such as dual-core processors are used to optimise utilisation, 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 EN954-1 up to Cat4, 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, and there are preinstalled 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.

Simatic WinAC RTX F can be expanded using the safety-oriented peripherals ET 200S, ET 200M and ET 200pro with IP67 protection, or with the safety-oriented ET 200eco block I/O with IP67 protection. A prerequisite is that the installed hardware provides the appropriate interfaces. This is the case with the Simatic Embedded Automation products. The Simatic S7-mEC-RTX F embedded controller can also be expanded with central ET200M I/O modules.
