Quality code
The process values of the function blocks are generated and transferred along with a signal
status as a structured variable. This contains a statement about the signal quality. The
function blocks determine the appropriate signal status for their process outputs depending
on the signal status of the process inputs. The signal status is formed from the input
parameters according to the priority table below (highest priority is 0). This group status is
displayed in the status bar of the faceplate and of the block icon. The signal status is
displayed for each individual parameter in the faceplate next to the process values.
