Parameter reassignment in RUN
If you reassign parameters in RUN, the following special characteristic applies.
SF LED is lit:
If a diagnostics was pending prior to reconfiguration, the SF LEDs (on CPU, IM or module)
may be lit even though diagnostics is no longer pending and the module is operating
correctly.
Solution:
● Only assign new parameters if no diagnostics is pending, or
● unplug module and plug it in again.
