Parameterization data
To set a configuration that deviates from the delivery state (="start-up configuration") or
to define actions in the Profibus "fail-safe" state and/or when response monitoring lapses
(e.g. master fails) (="fail-safe action"), up to six parameters, described with predefined
values on a case-by-case basis, can be defined for all modules. Eight-byte parameter-
ization data are added per parameter in the following format (undefined points to be as-
signed 0):
