8.6.2 Checking and reporting event status
There are several ways that event status can be determined:
• ProLink II automatically displays event information on the Informational panel of the Status
window, and also in the Output Levels window.
• For PROFIBUS hosts using the EDD, event status is displayed in the Device menu (see
Figure C-6).
• Using PROFIBUS bus parameters, event status is reported in the Diagnostic block, Index 9
(see Table D-4).
Note: You cannot view event status using a PROFIBUS host with the GSD.
Example
Define Discrete Event 1 to be active when the mass flow rate in forward
or backward direction is less than 2 lb/min or greater than 20 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. Set Flow Direction to Absolute Value. See Section 8.5.
3. Select Event 1.
4. Configure:
• Event Type = Out of Range
• Process Variable (PV) = Mass Flow Rate
• Low Setpoint (A) = 2
• High Setpoint (B) = 20
5. In the Discrete Input panel, open the dropdown list for Start/Stop
All Totalization and select Discrete Event 1.
Using PROFIBUS bus parameters:
1. Specify lb/min as the mass flow unit. See Section 6.3.1.
2. Set Flow Direction to Absolute Value. See Section 8.5.
3. In the Diagnostic block, set the following attributes:
• Discrete event index (Index 4) = 0
• Discrete event action type (Index 5) = 3
• Discrete event process variable (Index 8) = 0
• Discrete event setpoint A (Index 6) = 2
• Discrete event setpoint B (Index 7) = 20
• Discrete event assignment (Index 83) = 57
• Discrete event action code (Index 82) = 9
