Select Communications \ LevelMaster from the tree-view window of the PCCU32.
18.4.21
Click on Re-read to obtain a single set of readings from the HMA, or check the Monitor
checkbox to repeatedly read values from the HMA at the Interval specified in the Request
Blocks tabs in step 18.4.9.
18.4.22
In the example above, the attached device has the Measurement Type set to Interface,
the PV set to the Level reading and SV set to the Interface Level reading. The Upper Level
reading from the device (PV is sent as Float 1 of Command Uxx?) is displayed as Level 1.
The Interface Level reading from the device is displayed as Level 2. The Echo Strength
from the device is displayed as the Temperature. The Volume 1 value is computed from
the difference between the Level 1 and Level 2 readings. The Volume 2 value is computed
from the Level 2 reading. The level to volume conversion is determined by the settings
made in steps 18.4.15 through 18.4.19.
18.4.23
If the Measurement Type of the device is set to Level, the Level 1 and Level 2 readings will
be the same, Volume 1 will always be 0 and Volume 2 will represent the total volume.
18.4.24
Any Errors or Warnings from the attached HART device will appear under the bottom right
section of the tank image.
