TNC 360/TNC 335 Update information No. 2 1-1
Update Information No. 2
In earl September 1993 the software version 09 was released for the software types 260 02 and
280 49.
The new version contains the following changes:
•
If marker M2612 (Suppress position exchange in the tool table) is set before a T strobe is set
(M2046), the position numbers are not exchanged. The PLC acknowledges the T strobe without
having exchanged in the tool magazine and resets the PLC marker M2612. The new tool
number is shown inverted and the associated tool data (length and radius) are activated. The
tool number is shown inverted in the status display until the tool has physically been changed. If
the control is switched off and on in this condition, the last exchanged tool becomes active
again.
•
During execution of cycle 13 (spindle orientation) the NC sets the new marker M2408. This
marker can be evaluated by the PLC for the spindle orientation and should afterwards be reset
by the PLC.
