3.2 Product status indicator
The product status indicator changes its colour based on the
NAMUR recommendation NE 107 .
The colour of the product status indicator gives the following
pieces of information:
▪ Whether product diagnostics are active or not. Diagnostics are
active on the product and cannot be deactivated.
▪
If product diagnostics are active, then the product status indic-
ator shows whether diagnostics events have been generated or
not. If several diagnostics events have been generated, then
the product status indicator shows the diagnostics event with
the highest priority.
