1.9 PLC functions
Version entry for SPLC program in the OEM.SYS
For an SPLC program, a version identification can now be entered in the
OEM.SYS file. The identification must be assigned to the new token
SPLCSOFTVERS. The entry can be displayed by pressing the MOD key and
can be requested via LSV2.
The COPY SAMPLE FILES soft key can now also be used to create the
PLC:\PROTO\plc\SPlcApiMarker.def file again.
Detection of a spindle that is coasting to a stop after a restart
The current spindle speed is already available in the PLC word W322 or
D368 before the control voltage is switched on (not with CC 422).
Backing up and restoring the nonvolatile PLC memory
When creating service files or shutting down the control, the nonvolatile
memory of the PLC program is now saved automatically to the file
PLC:\JHPLCLOG\PLCREMADATA.LOG. Restoring the nonvolatile area from
the file is possible only by using the existing RESTORE M/B/W/D soft key in
the PLC mode of operation under the TABLE soft key.
Default language for text file
If you use the TEXTFILE command to show a text file in PLC mask files (PLC
Module 9210) and this file does not exist in the set language (MP7230.3),
the NC software now also searches the English language directory
(PLC:\LANGUAGE\ENGLISH) for the text file .
LSV2 message window possible without software option 18
Displaying a message window via an LSV2 telegram is now also possible
without software option 18 HEIDENHAIN DNC. The window was changed
to "GTK" and can be closed on the control by using CTRL + END or the Close
button of the window. You can now also define whether this window is to
be displayed in the Machine mode of operation, the Editing mode of
operation or in both modes of operation.
New word W1004
While an NC error message is being displayed, the associated error number
is saved to the new PLC word 1004. If no error message is active, the PLC
word has the value 0.
Modified: Behavior of M4623
The start of DNC operation can be disabled with the M4623. Until now this
also applied to TNCopt. As of this software version, you can start TNCopt
independently of marker M4623.
