Description of the parameterization of the SGA machine data MD36980 to

MD36990 and MD37901 to 37909

This machine data involves eight--digit hexadecimal numbers, where each digit has

a different significance that is now explained:

Coding of the output assignment is mm xx nn

SPL assignment

mm: SPL interface

System variable word index

Number of the system

variable bit

-- Input value of 0 means: there is no assignment, the output remains unaffec-

-- Input value of 80 00 00 00 means: there is no assignment, the output

remains fixed at 1.

-- If a single output signal is connected to a system variable, the following

applies: If MD bit 31 is set, then the signal is processed inverted.

-- If several output signals are connected to the same system variable, the

following applies: If MD bit 31 is set, then the relevant signal is initially inver-

ted. The (in some cases inverted) output signals are then AND'ed and the

result is entered in the system variable.

The maximum input value for all axis--specific NCK_SGA configuring machine

data is 84010620.

An incorrect entry will be detected the next time the system boots and flagged

using Alarm 27033.
