Diagnostic
Block_Err Possible Reasons
SELECT_TYPE = 0 (uninitialized)
Block Configuration error
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
The OUT Status of the CS block is the same of the Selected Input exception for:
• If input is Uncertain, the output is Bad unless the STATUS_OPTS is set to Use Uncertain as Good.
• If all the inputs are Bad the CS mode goes to MAN as well as it does the PID. This condition produces the OUT Status to be set to
IFS if the STATUS_OPTS is set to IFS if BAD IN.
• If no inputs have been linked or are valid the OUT Status is set to Bad - Configuration Error
Supported STATUS_OPTS:
• IFS if BAD IN
• Use Uncertain as GOOD
Status supported for other output variables:
• If the BKCAL_IN status is NI or IR, this status is transferred to the three BKCAL_SEL_x.
• If the BKCAL_IN status is not normal it is transferred to the selected BKCAL_SEL_x output.
• The BKCAL_SEL_x Status of the deselected inputs is set to Not Selected with the appropriate high or low limit set.
• When the CS is in MAN no inputs are selected. All the BKCAL_SEL_x status are set to Not Invited and Constant limits with the
same value of OUT.
Troubleshooting
Problem
The Block cannot be removed
from OOS mode
The Block is in MAN 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 Target Mode is set to MAN
An used input has Bad Status
The Selected input has UNCERTAIN 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
As Calculated and depending by the STATUS_OPTS
BAD + Out Of Service
Solution
Set the Target Mode to AUTO and/or remove the OOS
- Set the SEL_TYPE with a valid value. It must be different by 0
and in the range 1 – 3
- Set OUT_HI_LIM > OUT_LO_LIM
Set the Target Mode of the RESOURCE BLOCK to AUTO mode
Design the FB Application correctly and download it to the
devices
Set the Target Mode to AUTO
Check the upstream blocks
Set the STATUS_OPTS to Use Uncertain as Good
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
