tab, select the "IO tags" tab. This action displays the "Process value" and "Quality" bits for
the fail-safe module. Here, you can define tags for each channel:
Each Process value bit has an associated Quality bit that reports whether the
corresponding process value is valid or passivated. Quality bits are "ON" for valid data
and "OFF" for data associated with passivated channels.. If an entire module or a single
channel is passivated, the associated Quality bits are "OFF".
