Beckhoff TwinSAFE Logic Solutions
By MRO Magazine
New generation of Beckhoff TwinSAFE safety controllers based on EL6910 TwinSAFE Logic terminal, make it possible to adapt the TwinSAFE system more specifically to exact requirements of a machine concept as well as to a broader spectrum of programmable safety applications.
The new I/O components include:
˗ EL1918 TwinSAFE EtherCAT Terminal: digital terminal with eight safe inputs;
˗ EL2911 TwinSAFE EtherCAT Terminal: safe potential supply terminal with four safe inputs and one safe output;
˗ EP1957-0022 TwinSAFE EtherCAT Box: IP67-protected digital combi module with eight safe inputs and four safe outputs.
Three new I/O modules can be used as controllers for the direct execution of customer-specific safety projects. Like a dedicated controller, the safety project on the corresponding TwinSAFE I/O component can establish direct communication relationships with other safety-relevant devices and pre-process the data internally.
Safety projects can be modularly designed in TwinCAT software. However, the new customizing function enables each module to be configured into the following operating modes:
˗ temporary deactivation;
˗ permanent deactivation;
With the corresponding configuration of replacement values for the interfaces between the different modules, users can implement complex, modular and scalable architectures while reducing development costs.
