Operating modes
In operating mode, process values (PVs) from connected
sensors are displayed on Operator Pages. A maximum of 3
Operator Pages can be displayed.
Operator Page 1 (the default page) displays the PVs from all
connected sensors simultaneously (a maximum of 2 sensors
can be connected). The remaining 2 Operator pages display
values from individual sensors (in sensor order).
In Figure 20, Operator page 1 shows that 2 sensors are
connected (pH and turbidity).
