Diagnostic
Block_Err Possible Reasons
- SWAP_2 = 0 (uninitialized)
- No X, Y point set
- SWAP = FALSE and X values do not increase monotonically
- SWAP = TRUE and X values do not increase monotonically
Block Configuration error
OR Y values do not increase or decrease monotonically
Input Failure/process The value linked in input coming from the upstream
variable has BAD status blocks has BAD Status.
Out-of-Service The Actual_Mode is OUT OF SERVICE
NOTE A: The specific block cannot be switched out from OUT OF SERVICE due to the Configuration Error. The Bad-
Configuration Error Status is overridden by the Bad-Out Of Service Status.
OUT Status
OUT_1 shall reflect the status of IN_1 and OUT_2 shall reflect the status of IN_2. The sub-status shall also be passed to the outputs.
If one of the curve limits is reached or the input is limited, the appropriate limit should be indicated in the output sub-status. Limits
shall be reversed if the curve slope is negative.
If SWAP_2 is set, cascade initialization is controlled by the lower block. When this block is in O/S mode, the cascade to both the
lower and upper blocks shall be broken by Bad status at the outputs. When this block goes to Auto mode, the lower block can begin
cascade initialization with status values that pass through this block to the upper block. Answering status signals from the upper
block pass through this block to the lower block.
• The block does not use STATUS_OPTS.
Troubleshooting
Problem
The Block cannot be removed
from OOS mode
The OUT Status is BAD
The OUT Status has the Limit
bits (0, 1) set to Constant
Block Alarm Not Working
(Events not notified)
Possible cause
The Target Mode is not set to AUTO
The Configuration Error bit is set in the BLOCK_ERR
The RESOURCE BLOCK is not in AUTO mode
The Block is not scheduled
The used input has Bad Status
There are no inputs linked in (OUT Status = BAD
Configuration Error)
The Actual Mode is set to MAN
The FEATURE_SEL has not the Reports bit Set
LIM_NOTIFY value is less of the MAX_NOTIFY value
OUT Status
BAD + Out Of Service
See Note A
- The Status of IN_1 is propagated to the OUT_ 1
- The Status of IN_2 is propagated to the OUT_2
BAD + Out Of Service
Solution
Set the Target Mode to AUTO and/or remove the OOS
– Set SWAP_2 different by 0
– Set at least one X, Y pairs
– IF SWAP = FALSE set X points with increasing
monotonically values
– IF SWAP = TRUE set X points with increasing
monotonically values and Y points with increasing or
decreasing monotonically values
Set the Target Mode of the RESOURCE BLOCK to AUTO mode
Design the FB Application correctly and download it to the
devices
Check the upstream blocks
Review the FB application design
Set the Target Mode to AUTO
Set the REPORTS bit in the FEATURE_SEL of the RESOURCE
BLOCK
Set the value of LIM_NOTIFY equal, at least, to the MAX_NOTIFY
value
