ADVANCED

DIAGNOSTICS

TRANSDUCER BLOCK

(ADB)

This section describes error conditions found in the Advanced Diagnostics

Transducer Block. Read Table 5-11 to determine the appropriate corrective

action. Refer to Section 6 for complete information on Advanced Diagnostics.

Condition Name and Description

Other

Out of Service: The actual mode is out of service.

Symptom Possible Causes Recommended Action

PIL or SPM will not go to Learning. ADB Block is not licensed. The

algorithm Status will indicate “Not

Licensed.”

1. Check DIAG_OPTIONS in the Resource Block. PIL/SPM or a

hex value of 0x00000300 should be shown. See "Advanced

Diagnostics Transducer Block" on page 1-3.

Resource Block Actual Mode is

OOS.

Determine why the Resource block is in OOS. Correct problem

then put Resource Block into Auto mode

ADB block Actual mode is OOS. Put ADB block into Auto mode.

The algorithms were not activated

or configured properly..

To activate and configure SPM see page 6-6. To activate and

configure PIL, see page 6-25

For the SPM algorithm only: The

variable to be monitored is in an

unscheduled function block

Download a schedule into the function block. Consult your host

documentation for downloading schedules.

For SPM (only), the block in which

the process variable is coming

from is not in Auto mode.

Put monitored block into Auto mode.

PIL Status reads “Insufficient

Dynamics.”

There is not enough process noise

or there is no flow in the line.

1. Check to see if the process is flowing.

2. Your process may have low process dynamics. You can turn

off this check. This should only be done after considering the

possible results, see "PLINE_Learn_Sensitivity" on page 6-30.

The SPM or PIL Status stays in

Verifying.

The process dynamics are not

stable.

Ensure that the process flow is stable.

The learning period is too short Ensure that the SPM Monitoring Cycle or PIL Learning Length is

at least as long as any dominant cycling or oscillation in the

process. See pages 6-7 and 6-29.

(PIL Only) The PIL Learning

Sensivitivity is not properly

configured.

The process may be varying by more than the algorithm is

configured for. Adjust the learning sensitivity to compensate for

this, see "PLINE_Learn_Sensitivity" on page 6-30

The PIL Status reads “Bad PV

Status”

There is a problem in the Sensor

Transducer Block.

See "Rosemount 3051S troubleshooting flowchart" on page 5-2.
