Description of the parameterization of the SGE machine data MD 36970 to MD
36978
This machine data involves eight-digit hexadecimal numbers, where each digit has
a different significance that is now explained:
Coding of the input assignment
is mm
i Inversion
s Segment No.
mm Module No.
xx Sub-
module No.
nn I/O No.
If several output signals are set, then the signal involved is first inverted. The (in
some cases inverted) output signals are then AND'ed and the result is output at
the terminal.
Note
The maximum input value for all axial NCK_SGE configured machine data is
84020220.
An incorrect entry will be detected the next time the system boots and flagged
using Alarm 27033.
