Operation
Variables are linked to the alias devices in the Variable Mapping window. Use the Link button to open
the selection dialog for the alias port. Safe only signal types or safe and standard signal types are offered in
the selection dialog, depending on the port setting of the FB. Safe Boolean signals are shown with a yellow
background, standard signal types with a white background.
If several outputs are to be written by one variable, these signals can be assigned by holding down the CTRL
key and selecting the channels.

Once the development of the safety project is complete, the project has to be loaded onto the target system,
in this case EL6910/EJ6910. To this end the toolbars TwinCAT Safety and TwinCAT Safety CRC have to be
added.
