B&R X20cSL8101
openSAFETY manager for up to 280 SafeNODEs Flexibly programmable using Automation Studio / SafeDESIGNER Innovative management of safe machine options (SafeOPTION) Parameter and configuration management The module is equipped with SafeLOGIC functionality that allows it to safely execute applications designed in SafeDESIGNER. The module can be used in safety-related applications up to PL e or SIL 3. In addition, the module coordinates the safety-related communication of all modules involved in the application. In this context, the module also monitors the configuration of these modules and carries out autonomous parameter downloads to the modules whenever necessary. This guarantees a consistent and correct module configuration in the network from a safety standpoint in all scenarios involving module replacement and service. These services are performed by the SafeLOGIC controller.
