Caution
The MC 422 may only be exchanged in consultation with the machine manufacturer
or by the machine manufacturer!
MCs received for exchange and new MCs are normally equipped with the most recent
NC software.
This latest NC software must be released by the machine manufacturer!
Moreover, you need to know from the machine manufacturer whether there may be
conflicts related to fixed cycles, cutting data tables, etc. !
If the latest NC software has not been released by the machine manufacturer or if the
NC software version of your defective control should also run on the replacement control,
it must be loaded. Normally, you need support by the machine manufacturer.
Note: Dual-processor MCs have already loaded Windows 2000.
Move machine to home position (axed, tool changer, tilting head, etc.).
Ask the machine operator!
Press EMERGENCY-STOP.
Back up the condition of non-volatile PLC markers and words from RAM to the hard disk.
--> See "Nonvolatile PLC Markers and Words" on page 10 – 93.
Back up all control data on hard disk. Select the icon Scan everything.
--> See "Backup" on page 16 – 261.
Note
If an external archive for the TNC data is already available, you need not to back up the
TNC partition. Thus you save time!
Contact the customer!
In this case, select the icon Scan system and machine files.
Note
If you cannot back up data on the defective MC 422 anymore, you must go back to available
archives (PLC data, TNC data) to back up the data on the new control.
If required, you may obtain the machine data also from the machine manufacturer.
