Note
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
HDR is 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!
Press the END key.
