Updating the
machine
parameter list
If the control opens the machine parameter list after you have restored the back up, new
machine parameters are added with the current NC software of the replacement HDR or older
MPs are removed.
8 Press the END key.
The following messages may be generated:
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!
