Namur NE-107 Alarms
This section describes the parameter interaction to implement a
FieldQ™ QC54 Control module to the NAMUR NE-107 require-
ments as a parameter group in the Resource Block. There are
four alarm categories defined as per the NE-107 specification,
Failed, Off Specification, Maintenance, and Check function.
Maintenance Although the output signal is valid, the wear
reserve is nearly exhausted or a functions will soon be restricted
due to operational conditions e.g. build-up of deposits
Off Specification
Off-spec means that the device is operating
outside its specified range or an internal diagnostic indicates
deviations from measured or set values due to internal
problems in the device or process characteristics (e.g. bubble
formation in flow metering or valve sticking).
Check Function Output signal temporarily invalid (e.g. frozen)
due to on-going work on the device.
Failed Output signal invalid due to malfunction in the field
device or its peripherals.
Each of these categories share 32 conditions that can be defined

by the device manufacturer. Each condition may be mapped or
not mapped for each category. If a condition is mapped then it
is indicated in the* ACTIVE parameter. If the condition in the *
ACTIVE parameter is not masked by the
corresponding bit in the *_MASK parameter then the condition
will be queued for broadcast using the corresponding *ALM
parameter at the associated priority indicated by *PRI
parameter. The 4 categories are defined below.
The conditions are not expected to identify explicitly the root
cause of the condition, but rather to identify it in terms of:
• Replace the device
• Replace a part of the device
• Correct a configuration problem
• Fix something outside of the device
The above list is all that the operator needs to know to restore
his process functionality and if there are more than 31 device
conditions they should be grouped by definition into these bit
