Interface parameters
▷ Interface parameters I040 to I099 are set at the
factory and normally do not need to be adjusted.
CAUTION
Changing the default settings of the interface pa-
rameters will change the functions of the inputs
at terminals 1 to 41 and terminals 85 to 90, see
page 7 (Connection diagram).
