7.5.2 Using ProLink II
ProLink II provides a Status window that displays:
• Device (alarm) status
•Event status
• Assorted other transmitter data
7.5.3 Using a DeviceNet tool
Status information is located in the Diagnostics Object (0x66), Instance 1. This Object includes,
among other data:
• Alarm status (Attributes 12–17, Attributes 40–41)
• Event status (Attribute 11)
• Drive gain (Attribute 20)
• Tube frequency (Attribute 21)
• Left and right pickoff voltages (Attributes 23 and 24)
Use the Get service to read the required data. See Table C-7, or see the manual entitled Micro Motion
Model 2400S Transmitters for DeviceNet: Device Profile for detailed information.
7.6 Handling status alarms
Specific process or flowmeter conditions cause status alarms. Each status alarm has an alarm code.
Status alarms are classified into three severity levels: Fault, Information, and Ignore. Severity level
controls how the transmitter responds to the alarm condition.
Note: Some status alarms can be reclassified, i.e., configured for a different severity level. For
information on configuring severity level, see Section 8.8.
Note: For detailed information on a specific status alarm, including possible causes and
troubleshooting suggestions, see Table 11-2. Before troubleshooting status alarms, first acknowledge
all alarms. This will remove inactive alarms from the list so that you can focus troubleshooting efforts
on active alarms.
The transmitter maintains two status flags for each alarm:
• The first status flag indicates “active” or “inactive.”
• The second status flag indicates “acknowledged” or “unacknowledged.”
