Anticipation when returning the tool to the magazine
This management may be added in the PLC to improve tool change execution time while making
sure that the magazine cycle is completed before starting the next tool change.
For the tool change to be safer and more efficient, the PLC must set logic input /XINHMZ low with
the M6 to indicate that it is running to return the previous tool to the magazine. When all the steps
of the the execution of the M6 are completed and the magazine is ready to make another tool change,
the PLC must set logic input /XINHMZ high. This way, as soon the PLC receives the data of the M6,
it can raise the AUXEND signal and the part program may keep running while the tool is being
returned to the magazine.
With this management, is an error occurs in the last part of the PLC operation, when the history
and the magazine table have already changed, it prevents the real status of the magazine from not
matching the one assumed at the CNC.
This management will only take place if the T management is anticipated; i.e. if it is being executed
in automatic mode and with bit 12 of general parameter TOOLTYPE (P167) = 1.
The part program is not considered completed until the /XINHMZ mark is set to 1 indicating that
the tool has been put in the magazine. This is good for M30, M2 and the last line of the program.
While the /XINHMZ mark is low, the T will be highlighted in reverse video both in ISO mode and in
conversational mode.
Ground tools
A ground tool is one that is in the tool table but not in the magazine table.
A ground tool does not occupy any position in the magazine and is identified with the value -4 in
TBCD (when requesting the tool) and in T2BCD (when returning it to the magazine).
Ground tool processing is activated with the same bit of anticipated T.
