(3) Display of first process value (PV1) including signal status
This area indicates the current first process value (PV1) with the associated signal status. The
name of the configured measured value is displayed depending on the PV1Meas tag, in this
case "Volume".
(4) High and low scale range for the gradient value
These values provide information on the display range for the bar graph of the gradient. The
scale range corresponds to 10% of the scale range for the first process value (PV1): If you have
entered a scale range for the process value of 0 to 100, for example, the scale range for the
gradient is automatically defined as -10 to 10.
The current gradient value is displayed if one of the monitoring functions is enabled:
● Gradient monitoring for positive changes (GradHUpEn = 1)
● Gradient monitoring for negative changes (GradHDnEn = 1)
● Gradient monitoring (GradLEn = 1)
(5) Display of gradient
This area shows the current, minimum and maximum gradient values of the first process
value PV1 as well as rising and falling of the value. This display of the minimum and maximum
gradient value functions like a slave pointer.
The current gradient value is displayed if one of the monitoring functions is enabled:
● Gradient monitoring for positive changes (GradHUpEn = 1)
● Gradient monitoring for negative changes (GradHDnEn = 1)
● Gradient monitoring (GradLEn = 1)
The maximum peak gradient value is displayed if the gradient monitoring function for positive
changes is enabled (GradHUpEn = 1)
The minimum peak gradient value is displayed if the gradient monitoring function for negative
changes is enabled (GradHDnEn = 1)
(6) Resetting of peak values of the gradient
Using these buttons you can reset the maximum or minimum peak value of the gradient (output
parameters PV1GradPP and PV1GradNP).
The button is displayed if the gradient monitoring function for positive (GradHUpEn = 1) or
negative (GradHDnEn = 1) changes is enabled.
(7) High and low scale range for the second process value (PV2)
This area indicates the current second process value (PV2) with the associated signal status.
The name of the configured measured value is displayed depending on the PV2Meas tag, in
this case "Distance".
