Table 10.3 Device Troubleshooting C

• Device output is not updating.
Possible Cause
Resource block mode is OOS
Resource block is not running.
Incorrect revision of resource
block firmware.
Incorrect revision level of the
device firmware.
Transducer block mode is OOS
Transducer block is not producing
valid primary data.
Analog Output block mode is OOS
AO block is not initialized
PID block is not initialized
PID block mode is OOS
Symptom
Items to Check
Read MODE_BLOCK. ACTUAL of
Resource block.
Read the first element of
BLOCK_TEST. Number should be
increasing indicating that block is
running. If block is not running,
check the second element of
BLOCK_TEST.
Check BLOCK_ERR for other
errors.
If an error is present in BLOCK_
ERR, then read ERROR_DETAIL.
Read DEV_TYPE , DEV_REV, and
DD_REV.
Read REVISION_ARRAY.
Read MODE_BLK . ACTUAL.
1. Read the first element of
BLOCK_TEST. Number should be
increasing indicating that block is
running. If block is not running,
check the second element of
BLOCK_TEST.
2. Read BLOCK_ERR.
3. Verify parameter FINAL_VALUE
is not valid STATUS = good or
uncertain VALUE = active
4. Read FINAL_POSITION VALUE;
should contain the position. Iso-
late valve from process and check
calibration.
Read MODE_BLK.ACTUAL of AO
block.
1. CHANNEL
2. SHED_OPT
SHED_OPT
Read MODE_BLK.ACTUAL of PID
block.
Recommended Action
If necessary, set MODE_BLOCK.
TARGET to Auto.
If second element of BLOCK_TEST
is not zero, write all zeroes to
element.
See Sub-section 10.7 for details
on BLOCK_ERR.
See Sub-section 10.7 for details
on ERROR_DETAIL parameter.
Set RESTART to processor (or '4')
to soft-restart the device.
See Incorrect or non-compatible

be in AUTO mode for the sensor
signal to be passed to 'AO block.'
If second element of BLOCK_TEST
is not zero, write all zeroes to
element.
See Sub-section 10.7 for details
on BLOCK_ERR.
Report information to factory.
Set MODE_BLK .TARGET to auto.
1. Set to 1
2. Set to a value other than Un-
initialized
Set to a value other than uniniti-
alized.
Set MODE_BLK.TARGET to Auto.
