2.5.5 Resource block
This section describes error conditions found in the Resource block. Read Table 2-8 through Table 2-10
to determine the appropriate corrective action.
Block errors
Table 2-8 lists conditions reported in the BLOCK_ERR parameter.

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.
3 Simulate Active: Simulation is enabled and the block is using a simulated value in its execution.
7
Input Failure/Process Variable has Bad Status: The hardware is bad, or a bad status is being
simulated.
14 Power Up
15 Out of Service: The actual mode is out of service.

CONFIGURATION ERROR
1. Check CHANNEL parameter (see “CHANNEL” on page 14 )
2. Check L_TYPE parameter (see “L_TYPE” on page 14 )
3. Check XD_SCALE engineering units. (see “XD_SCALE and
OUT_SCALE” on page 14
BLOCK_ERR reads POWERUP

BLOCK_ERR reads BAD INPUT
1. Sensor Transducer Block Out Of Service (OOS)
2. Resource Block Out of Service (OOS)
No BLOCK_ERR but readings
are not correct. If using
Indirect mode, scaling could
be wrong.
1. Check XD_SCALE parameter.
2. Check OUT_SCALE parameter.
(see “XD_SCALE and OUT_SCALE” on page 14 )
No BLOCK_ERR. Sensor needs
to be calibrated or Zero
trimmed.
See Section 2: Configuration to determine the appropriate
trimming or calibration procedure.
OUT parameter status reads
UNCERTAIN and substatus
reads EngUnitRangViolation.
Out_ScaleEU_0 and EU_100
settings are incorrect.
See “XD_SCALE and OUT_SCALE” on page 14 .
