8.1.32 Expanded PLC module interface for 18 axes
Up to 18 NC axes are available in an HSCI system. This was done by increasing
the greatest possible entry in the AXISNUMBER token of OEM.SYS from 14
to 18. Up to now, the PLC interface also supported only 14 axes. In order to
use the increased number of axes, you must set bit 14 of MP4020.
If the expanded PLC module interface is active, the spindle bit moves to bit 31
and the axis number (constant) for the spindle to K 31 for the following PLC
modules:
Please keep in mind that the parameters of PLC modules with bit-encoded
axis masks or constants for axes and spindles are set and interpreted in
different ways, depending on MP4020 bit14.
