Host computer
operation
The "Host Computer Operation" soft key is displayed in the MOD dialog in the
programming modes screen. If this operation is selected, then no files (NC
programs) are open anymore in the Editing and Test Run operating modes.
The PLC can interrogate Marker M4630 to determine whether host computer
operation is active. Deactivation of host computer operation via soft key can
be disabled via PLC Marker M4631. This enables the PLC program to ensure
that host computer operation can only be activated if it is useful and will not
cause problems.
The PLC can control host computer operation using Module 9036 (identifier
1000).
A program list (NC programs) can be transferred to the TNC. The list can then
be used to generate entire tool usage files and tool usage times. This makes
it possible to specify the NC programs and their sequence, as well as the tools,
through an external host computer. If external tool data are already available,
these data can also be transferred (as a *.CSV file) to the control, if desired,
and be used.
The host computer transfers a table (with only one column PATH) together
with the NC program sequence. This .TAB file can be generated as a freely
definable table on the control and be transferred to the host computer by
means of TNCremo. There, the NC program list can be edited anytime.
In addition, a CSV file containing information for incorporation into the tool
usage file can be transferred, if desired. The file must contain the columns
NAME and/or tool number T, as well as the columns TIME and PATH. The TIME
column shows the time (in seconds) during which the tool is engaged. If the
tool name and the tool number are contained, both will be transferred, but
the tool number has priority. Each column, even if it is empty, is concluded
with a semicolon in CSV format. Example of a CSV file:
NAME TIME PATH T
CUTTER5MM 235 TNVC:\AUFTR1\NcPrgrm1.h 12
DEEPHOLEDRILL
123
33 TNVC:\AUFTR1\NcPrgrm1.h
CUTTER12MM 60 TNVC:\AUFTR1\NcPrgrm1.h
DRILL5MM 60 TNVC:\AUFTR1\NcPrgrm2.h
