1.5 New functions
Keys are also effective for active third desktop
The NC start key is now also effective on the third desktop (OEM screen)
and is transferred to the NC (start of an NC program, if required).
Furthermore, the ERR or HELP key now opens the error list and/or help text
window on the third desktop.
Speed monitoring for slave axes
Machine parameter MP855.x (synchronization monitoring) is now effective
for all slave axes of a synchronized drive (if a value > 0 has been entered),
regardless of whether it is a gantry or master-slave combination. Until now
this monitoring function was only effective for position controlled slave axes
of a gantry combination.
Preset table in inches
The values in preset tables will now be shown in inches if the control was
set to inches. When the files are output, the data will be saved without unit
as before, i.e. converted files must always be interpreted in mm format.
Compensation values with higher resolution in the compensation
tables
Compensation values with six decimal places (1 nm) can now be entered in
the compensation tables (*.COM).
New function for HE Logging
The new tab Memcheck is now available in the HE Logging menu. Just like the
existing tabs for the settings regarding Syslog, FTrace, and TCPDump, these
possibilities for diagnostics and the associated settings are to be used only
together with HEIDENHAIN service personnel.
Access to data from the NC program
The new NC blocks DATA ACCESS READ and DATA ACCESS WRITE have
been introduced. These blocks make it possible for an NC program to
access specific data of the NC or PLC. The same interface is used as for data
access with Python. The subscription to and unsubscription from data take
place automatically. The access rights are determined by the directory
where the executing NC program is stored (TNC:\, PLC:\). Example:
0 BEGIN PGM DATA_RW MM
1 ;Read tool name of T2 from TOOL.T
2 DATA READ QS8 = "\TABLE\TOOL\T\2\NAME"
3 ;Tool radius of T2 from TOOL.T
4 DATA READ Q8 = "\TABLE\TOOL\T\2\R"
5 ;Write tool name of T5 in TOOL.T
6 DATA WRITE "\TABLE\TOOL\T\5\NAME" = QS8
7 ;Write tool radius of T5 in TOOL.T
8 DATA WRITE "\TABLE\TOOL\T\5\R" = Q8
9 ;Coordinate from line 5 of the KINEMAT0.TAB
10 DATA READ QL1 = "\TABLE\'TNC:\KINEMAT0.TAB'\NR\5\COORD"
11 ;File name from line 1 of the KINEMAT0.TAB
12 DATA READ QS15 = "\TABLE\'TNC:\KINEMAT0.TAB'\NR\1\FILE"
13 ;Write coordinate to line 7 of the KINEMAT0.TAB
14 DATA WRITE "\TABLE\'TNC:\KINEMAT0.TAB'\NR\7\COORD" = QL1
15 ;Write file name to line 2 of the KINEMAT0.TAB
16 DATA WRITE "\TABLE\'TNC:\KINEMAT0.TAB'\NR\2\FILE" = QS15
17 ;Read PLC word 4000
18 DATA READ QR1 = "\PLC\memory\W\4000"
19 ;Write to PLC word 4002
20 DATA WRITE "\PLC\memory\W\4002" = QR1
21 END PGM DATA_RW MM
