communication with the smart device. The third message is generated when an error is detected

for a specific smart device when data is being downloaded to the transmitter from the Smart

Device Tuning Overview Display. To view the message, use the ALL TEXT option of the

Diagnostic Package.

All three messages above have 4 digits reserved for identifying the smart device that failed,

resumed communication, or generated an error. The first 2 digits identify the network address

(1-31) of the SHIM to which the smart device is connected. The last 2 digits identify the

transmitter address (1-8) where the smart device is connected to the SHIM. Note that the smart

device’s transmitter address is preceded by a 0 (zero), and SHIM network addresses 1 through 9

are preceded by a blank space. The first and third message above also contain a second number.

In the first message the second number has 2 digits reserved for identifying the serial I/O port to

which the SHIM is connected. This allows you to easily locate the smart device in the field and

correct the problem. The second number in the third message is 3 digit value you must decipher

to determine the problem with the smart device. The value indicates a device-specific error

code, resulting from a download error generated when data is being downloaded to the

transmitter from the Smart Device Tuning Overview Display. Consult the documentation

provided by the smart device’s manufacturer for details on the code’s meaning.

All of the following messages indicate field device status problems:

SMART DEV 201 NON-PV OUT OF SENSOR LIMITS

SMART DEV 201 NON-PV BACK IN VALID RANGE

SMART DEV 201 PV OUT OF SENSOR LIMITS

SMART DEV 201 PV BACK IN VALID RANGE

SMART DEV 201 PV ANALOG OUTPUT FIXED MODE

SMART DEV 201 PV ANALOG OUTPUT NORMAL MODE

SMART DEV 201 PV ANALOG OUTPUT SATURATED

SMART DEV 201 PV ANALOG OUTPUT NON-SATURATED

The numbers in the above messages identify the smart device in the field in the same manner as

described above.

Process alarms, bad data quality, and so on is handled directly by CCF based on the input from

the input tables accessed by CCF.

Runtime tuning changes to the smart transmitter data base made by the operator at the Advant

OCS console are logged by the Event Logging Package. Tuning changes made with a hand-held

monitor are not logged.
