2.6 Differences in comparison with the technology card
The setpoint exchange implemented in NCK SW 7.1 and higher differs from the compile
cycles solution described in TE5 as follows. These differences must be taken into account
during installation and start-up and when creating the PLC user program:
• The machine data MD63750 is no longer required.
• The meanings of associated interface signals have changed. Therefore, PLC user
• Alarms 70451 and 70452 are no longer used.
• Setpoint exchange with simulated axes (MD30130=0) is no longer supported.
• Known restrictions of the technology card function no longer apply.
