Restoring the data

As you could probably not store data from the defective HDR, you must now go back to available

archives (PLC-data, TNC-data) to restore data on the new HDR; if required, the machine

manufacturer can also provide you with PLC or machine data.

Load the backup on the new HDR. --> See "Restore" on page 16 – 266.

Delete the blue check mark for LIES_MP.A in the LST file.

To each NC software version belongs a LIES_MP.A file which includes the comments on the

current machine parameters (to be found under PLC:\JH\LIES_MP.A). As the replacement

control is normally supplied with the latest NC software version, the LIES_MP.A in your

backup file possibly belongs to an older NC software version. If you have deleted the check

mark in your LST file, the new LIES_MP.A is not overwritten by the old LIES_MP.A.

It is not recommended to protect the LIES_MP.A file on the control as otherwise the file

cannot be updated during an NC software update!
