Filter

The measured value of each analog input can be filtered with a digital filter.
5.2.4.1 Enable filter
Measured value jumps when enabling or disabling filters
When filters are enabled or disabled, short-term measured value jumps can occur in the process data that
do not correspond to the physical values.
You can enable the filter individually for each input. All filters are disabled in the factory setting.
Enable the filter by setting the following CoE parameters to TRUE:
Connection
X01
X02
X05
X06
The enabling of filters also affects the synchronization mode:
• If all filters are disabled, the device runs in the synchronization mode "Synchron with SM event"
• If one or more filters are enabled, the device runs in the synchronization mode "Free Run".
