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 Section 8.5.

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 Section 8.5.

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
