Alarm Categories (NAMUR NE-107)

Field Diagnostics uses the classification of NAMUR NE-107, which are defined as follows:
• Failure – Output signal invalid due to malfunction in the field device or its peripherals e.g. a
broken glass electrode.
• Out of Specification – The device is operating outside its specified range or an internal diag-
nostic indicates deviations from measured or set values due to internal problems in the
device or process characteristics e.g. a high temperature condition.
• Maintenance – Although the output signal is valid, the wear reserve is nearly exhausted or a
function will soon be restricted due to operational conditions.
• Check Function – Output signal temporarily invalid (e.g. frozen) due to on-going work on
the device.

Field Diagnostics Configuration

Field Diagnostics can be configured to meet the requirements of the transmitter application and
tested using the following actions:
• Map – Maps alarms to a particular alarm category
• Priority – Sets the priority of each alarm category
• Mask – Suppresses the broadcast of any alarm or alarms to the host
• Simulate – Allows alarms to be manually simulated; requires the simulate jumper to be in
place on the 1066pH circuit board.

PlantWeb Alerts

Legacy hosts, such as DeltaV version 10.3, cannot implement Field Diagnostics, but can imple-
ment PlantWeb Alerts. The 1066pH also supports PlantWeb Alerts, which has different categories
for classifying diagnostic alarms. They are:
• Failed
• Maintenance
• Advisory
• No Category
9.4.4

PlantWeb Alerts Configuration

As with Field Diagnostics, PlantWeb Alerts can be configured per the application requirements:
• Enable (Map) – Maps alarms to a particular alarm category
• Priority – Sets the priority of each alarm category
