Restore
If a project that doesn't match the system is loaded during a
restore
, this will only be detected when
the distributed CRCs are checked. The previous project is then deleted from the logic terminal. This
cannot be undone.
One possible sequence for checking whether a restore is carried out is shown in the following sequence
chart.

Function blocks for backup/restore
The PLC function blocks with which a backup and restore to a TwinSAFE logic component (currently
EL6910, EJ6910 or EK1960) can be carried out are available through Beckhoff Support. This is a compiled
library that can be installed in the TwinCAT Library Repository.
The TC3_EL6910_Backup_Restore library contains two PLC function blocks. FB_SAVELOGICPROGRAM
and FB_RESTORELOGICPROGRAM.
FB_SAVELOGICPROGRAM
