Block_Err
Possible Reasons
OUT Status
Block Configuration error
– 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 OR Y values do
not increase or decrease monotonically
BAD + Out Of Service
See Note A
Input Failure/process
variable has BAD status
The value linked in input coming from the upstream blocks has BAD Status.
– The Status of IN_1 is propagated to the OUT_ 1
– The Status of IN_2 is propagated to the OUT_2
Out-of-Service
The Actual_Mode is OUT OF SERVICE
BAD + 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
Possible cause
Solution
The Block cannot be removed
from OOS mode
The Target Mode is not set to AUTO
Set the Target Mode to AUTO and/or remove the OOS
The Configuration Error bit is set in the BLOCK_ERR
– 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
The RESOURCE BLOCK is not in AUTO mode
Set the Target Mode of the RESOURCE BLOCK to AUTO mode
The Block is not scheduled
Design the FB Application correctly and download it to the devices
The OUT Status is BAD
The used input has Bad Status
Check the upstream blocks
There are no inputs linked in (OUT Status = BAD
Configuration Error)
Review the FB application design
The OUT Status has the Limit
bits (0, 1) set to Constant
The Actual Mode is set to MAN
Set the Target Mode to AUTO
Block Alarm Not Working
(Events not notified)
The FEATURE_SEL has not the Reports bit Set
Set the REPORTS bit in the FEATURE_SEL of the RESOURCE BLOCK
LIM_NOTIFY value is less of the MAX_NOTIFY value Set the value of LIM_NOTIFY equal, at least, to the MAX_NOTIFY value
