Table B‐40. BLOCK_ERR Conditions
Condition Number Condition Name and Description
0 Other - the output has a quality of uncertain.
1
Block Configuration Error ‐ the selected channel carries a measurement that is incompatible with the engineering units
selected in XD_SCALE, the L_TYPE parameter is not configured, or CHANNEL = zero.
2 Link Configuration Error
3 Simulate Active
4 Local Override
5 Device Fault State
6 Device Needs Maintenance Soon
7 Input failure/process variable had Bad status ‐ The hardware is bad, or a bad status is being simulated
8 Output failure
9 Memory failure
10 Lost Static Data
11 Lost NV Data
12 Readback Check Failed
13 Device Needs Maintenance Now
14 Power Up ‐ This condition exists until the AI function block executes for the first time.
15 Out of Service ‐ The actual mode is Out of Service.
Troubleshooting
Refer to table B‐41 to troubleshoot any problems that you encounter.
Table B‐41. Troubleshooting
Symptom Possible Causes Corrective Action
Mode will not leave OOS
Target mode is not set Set target mode to something other than OOS
Configuration error
BLOCK_ERR [6] will show the configuration error set. ARITH_TYPE must be
set to a valid value and cannot be left at 0.
Resource block
The actual mode of the Resource block is OOS. See Resource Block
Diagnostics for corrective action.
Schedule
Block is not scheduled and therefore cannot execute to go to the target
mode. Typically, BLOCK_ERR will show “Power-Up” for all blocks that are
not scheduled. Schedule the block to execute.
Status of outputs is BAD Inputs Input has BAD status.
Block Alarms will not work
Features FEATURES_SEL does not have Alerts enabled. Enable the Alert bit.
Notification D LIM_NOTIFY is not high enough. Set equal to MAX_NOTIFY.
Status Options
STATUS_OPTS has the Propagate Fault Forward bit set. This must be
cleared to cause the alarm to occur.
