Dependencies
With certain combinations of machine data, restrictions in the value range
arise for non-processing of the machine data.
These dependencies are verified on acceptance of the MD DB or individual
machine data, and an error message is output in the event of a violation.
Some checks are performed on the basis of internally calculated reference
variables.
These reference variables and the dependency checks are described in the
tables below.
Reference variables generated internally from MD:
Generation of travel per encoder revolution UMWEG
UMWEG = MD11 + MD12 2
Generation of internal measured value factor
