5.3.8 EL1918: using the integrated TwinSAFE Logic functions
In addition to its standard function as a digital safe input terminal, the EL1918 TwinSAFE Terminal also
supports the option of executing a local safety-related user program. To do this, select the EL1918 as the
target system in the TwinCAT Safety Editor.
Information on creating a safety user program can be found in the documentation for the EL6910 (see
References).
The default project, so that the EL1918 once again behaves as a safe input terminal, can be reactivated by
deleting the safety-related user program from the TwinSAFE component. To do this, select the entry Safe
Logic, Mapping and Parameter Data in the dialog for deleting the project. After switching the TwinSAFE
component off and on, the default project is active again.

5.3.8.1 Project design limits of EL1918
Project design limits
The maximum project design size for EL1918 is determined by the available memory. This is
managed dynamically. The values specified in the following table are therefore only guide values
and may differ from the actual values, depending on the safety project.
