The EL6910 represents the new generation of dedicated safety controllers. While the EL6900 as its predecessor provided only
function blocks based on Boolean values, the EL6910 offers a wide variety of certified function blocks that enable the safe
processing of analog values and thus the implementation of even more complex safety applications.
In addition to the extension of the processable data types, the so-called customizing function has been established in order
to be able to appropriately map current requirements for non-safety-oriented applications with regard to modularization and
dynamization in the field of safety technology too. Customizing allows modules of the safety application to be configured so
that they are capable of being permanently or temporarily disabled. The disablement or re-enablement can also take place
subsequently at runtime.
The EL6910 TwinSAFE Logic can establish 212 connections to other devices. In addition to safe communication connections via
FSoE, connections via PROFIsafe are also possible (master and slave). TwinSAFE SC technology is also supported. This
technology allows analog signals from the actual standard EtherCAT I/Os (with the identifier -009x) to be safely transmitted
to a TwinSAFE Logic-capable component and used there to check the plausibility of this analog signal and to use it in terms of
safety using another diversified analog signal (usually up to PL d).
Another highlight of the introduction of the new controller generation is the incremental download. In contrast to its
predecessor, the safety project now consists of four components (logic, parameters, mapping, info data), each of which has its
own checksum. Thus, in the event of a change to the safety project, an effect analysis can be performed on the basis of these
sub-checksums. This simplifies the validation and verification of the safety project. This division is also reflected in the
extended user management, so that rights can now be granted on the basis of different components (e.g., a user who can
only change the information data of a safety project).
Finally, the new generation of safety controllers now has a diagnostic history directly on the component. All errors that have
occurred can be read directly from the component and evaluated.
The EL6910 is programmed using the TwinCAT 3 Safety Editor.
