Adapting the
MPNAME.MP
Only necessary if you want to transfer the backup files by means of Ethernet interface
and the NC software version of the control is lower than 340420-08!
If the file MPNAME.MP is now displayed on the screen:
8 Press END to restart the control.
Setting date and
time on the control
8 Check the date and time of the control and reset it, if necessary. --> See “Setting the System
Time” on page 12 – 159.
Setting up the data
interface
8 Make the settings for Ethernet transmission on the control.
--> See “Via Ethernet” on page 13 – 172.
Subsequently, protect the IP4.N00 file to make sure it is not overwritten!
8 Or define the settings for the RS 232 interface.
--> See “Via serial interface RS-232-C or RS-422” on page 13 – 182.
Defining the NC
software version
8 Check the currently active NC software version. --> See “Display of Important System
Information” on page 26 – 443.
If you need another software version, it must be loaded now. --> Contact the machine
manufacturer!
Restoring the data As you could probably not store data from the defective hard disk, you must now go back to
available archives (PLC-data, TNC-data) to restore data on the new hard disk; if required, the
machine manufacturer can also provide you with PLC or machine data.
8 Establish a connection between your laptop and the control.
--> See “Connection Setup” on page 13 – 172.
8 Load the backup on the new hard disk of the MC 422.
--> See “Restoring Data” on page 13 – 197.
If entries for additional control-loop indexes are now required in the machine parameter list
(error message MP: not defined) or there seem to be too many control-loop indexes (error
message MP: incorrect number), then ...
Delete the MPNAME.MP. -->
An adapted MPNAME.MP is generated automatically.
Press END. -->
The control boots and generates the Power interrupt message.
As of NC software version 340420-08, the code number NET 123 for setting up the Ethernet
configuration is also accepted with open MP list.
Delete the blue check mark for READ_MP.A in the LST file.
Background:
To each NC software version belongs a READ_MP.A file which includes the comments on the
current machine parameters (to be found under PLC:\JH\READ_MP.A). As the replacement
drives are normally supplied with the latest NC software version, the READ_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 current READ_MP.A is not overwritten by the old READ_MP.A.
It is not recommended to protect the READ_MP.A file on the control as otherwise the file
cannot be updated during an NC software update!
