Diagnostic Messages

ALARM DRIFT ALERT
The analog output is in alarm. Drift Alert alarm is enabled and the
difference between Sensor 1 and Sensor 2 has exceeded the
user-specified limit. The transmitter is still operating, but one of the
sensors may be malfunctioning. The Process Variable line displays
"ALARM" and the Process Variable Unit line alternates between "DRIFT"
and "ALERT."
ALARM
The digital and analog outputs are in alarm. Possible causes of this
condition include, but are not limited to, an electronics failure or an open
sensor. This message is displayed on the Process Variable line and is
always accompanied by a more descriptive message on the Process
Variable Unit line. In the case of a Sensor 1 failure, for example, the
Process Variable line displays "ALARM," and the Process Variable Unit
line alternates between "SNSR 1" and "FAIL."
WARN
The transmitter is still operating, but something is not correct. Possible
causes of this condition include, but are not limited to, an out-of-range
sensor, a fixed loop, or an open sensor condition. In the case of a Sensor
2 failure with Hot Backup enabled, the Process Variable line displays
"WARN," and the Process Variable Unit line alternates between "SNSR 2"
and "RANGE."
The following is a list of messages used by the Model 275 HART
Communicator and their corresponding descriptions.
Variable parameters within the text of a message are indicated with <variable
parameter>.
Reference to the name of another message is identified by [another
message].
Message
Add item for ALL device
types or only for this ONE
device type
Command not implemented The connected device does not support this function.
Communication error
Configuration memory not
compatible with connected
device
Device busy
Device disconnected
Device write protected
Device write protected. Do
you still want to shut off?
Display value of variable on
hot key menu?
Description
Asks the user whether the hot key item being added should be
added for all device types or only for the type of device that is
connected.
Either a device sends back a response indicating that the
message it received was unintelligible, or the HART
Communicator cannot understand the response from the device.
The configuration stored in memory is incompatible with the
device to which a transfer has been requested.
The connected device is busy performing another task.
Device fails to respond to a command.
Device is in write-protect mode. Data can not be written.
Device is in write-protect mode. Press YES to turn the HART
Communicator off and lose the unsent data.
Asks whether the value of the variable should be displayed
adjacent to its label on the hot key menu if the item being
added to the hot key menu is a variable.
