CODESYS Virtual Safe Control SL is a software-based safety controller that does not require a defined, two-channel hardware substructure according to IEC 61508. It can therefore run on any hardware, currently with x86 architecture (ARM-based platforms in preparation). To do this, the processing of the application software is distributed across two logical software channels – using “diversified encoding”, which is based on the well-known “coded processing” method. This ensures the same safety level as known from two-channel hardware solutions. CODESYS Virtual Safe Control SL enables the control of safe fieldbus I/Os via Ethernet-based safety protocol (currently PROFIsafe, FSoE in preparation).
Features
Certified Safety
CODESYS Virtual Safe Control is certified according to IEC 61508 for applications requiring Safety Integrity Level 3 (SIL3).
Safety up to SIL 3
Hardware fault tolerance (HFT) of 1, maximum probability of failure (PFH) of 1 * 10 -10.
Usability
The safety application is engineered directly in the CODESYS Development System along with the functional application. The certified add-on CODESYS Safety Extension is used for this purpose.
Seamless Integration
CODESYS Virtual Safe Control integrates perfectly into existing CODESYS environments. Take advantage of established development tools and methods for your safety applications.
Take advantage of virtualization
Reduce hardware costs, enjoy greater freedom in hardware selection, optimize your IT resources, and make your automation solutions even more flexible.
