Changes the active enhanced density curve from 1 to
2, from 2 to 3, etc.
(1) Displayed only if Volume Flow Type = Liquid.
(2) Displayed only if Volume Flow Type = Gas.
(3) Available only if the petroleum measurement application is installed.
(4) Available only if the enhanced density application is installed.
Example
Define Event 1 to be active when the mass flow rate in forward or
backward direction is less than 2 lb/min. Additionally, if this occurs, all
totalizers should be stopped.
Using ProLink II:
1. Specify lb/min as the mass flow unit. See Section 6.3.1.
2. Configure the Flow Direction parameter for bidirectional flow. See
3. Select Event 1.
4. Configure:
•
Event Type = Low
•
Process Variable (PV) = Mass Flow Rate
•
Low Setpoint (A) = 2
5. In the Discrete Input panel, open the dropdown list for Start/Stop
All Totalization and select Discrete Event 1.
Using a DeviceNet tool:
1. Specify lb/min as the mass flow unit. See Section 6.3.1.
2. Configure the Flow Direction parameter for bidirectional flow. See
3. In the Diagnostics Object (0x66), Instance 1, set the following
attributes:
•
Discrete event index (Attribute 6) = 0
•
Discrete event action (Attribute 7) = 1
•
Discrete event process variable (Attribute 10) = 0
•
Discrete event setpoint A (Attribute 8) = 2
•
Discrete event action code (Attribute 84) = 9
•
Discrete event assignment (Attribute 85) = 57
