Counting whenever a value changes in a column

[Odko]

Hi everyone,

I need to implement the column “group” shown in the screenshot below.
The logic is such that this column will keep counting whenever there is a value change (from 0 to 1, or 1 to 0) in column “low_glucose”. If possible, I’d like to implement it using only KNIME-specific nodes.

Thank you very much!
