4.2.3 Reading
Mask
In VisiSet™, if the Array Layout Monitor parameter in the Display folder is enabled, it
changes the appearance of the reading mask.
Array Layout Monitor Enabled
If the Array Layout Monitor parameter is enabled, on row one, the display shows the result of
the reading phase: code content, or read event message.
Row two shows the reading phase counter and read rate counting from the last restart of the
system. These values are reset if the reader configuration is changed or a manual reset of
the statistics is performed (Init Counters).
On row three, the reading mask for the master and slave readers (ordered from left to right)
is shown with the numbers 0 and 1. A successful read is presented as a 1 for the readers
who have read the code.
The network state on row four has the same meaning as in par. 4.2.2.
