Block_Err
Block Configuration error
Local Override
Input Failure/process variable has
BAD status
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 can be affected by the setting of the STATUS_OPTS
Troubleshooting
Problem
The Block cannot be
removed from OOS mode
The Block cannot be
removed from IMAN mode
The Block cannot be
switched in AUTO mode
The Block cannot be
switched in CAS mode
Block Alarm Not Working
(Events not notified)
Possible Reasons
• SHED_OPT = 0 (uninitialized)
• BYPASS = 0 (uninitialized)
• OUT_HI_LIM =< OUT_LO_LIM
• SP_HI_LIM =< SP_LO_LIM
MODE_BLK.Actual = Local Override
BAD quality Status in input at the PID_IN.
The Actual_Mode is OUT OF SERVICE
Possible cause
The Target Mode is not set different of OOS
The Configuration Error bit is set in the BLOCK_ERR
The RESOURCE BLOCK is not in AUTO mode
The Block is not scheduled
Something wrong in the BKCAL_IN
The Target Mode is not set to AUTO
Something wrong in the IN
The Target Mode is not set to
CASCADE
Something wrong in the CAS_IN
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
NO EFFECT
Depends by the STATUS_OPTS
BAD + Out Of Service
Solution
Set the Target Mode to something different from OOS
• Set the OUT_HI_LIM > OUT_LO_LIM
• Set the SP_HI_LIM > SP_LO_LIM
• Set BYPASS to ON or OFF but different from 0
(uninitialized)
• Set SHED_OPT different from 0
Set the Target Mode of the RESOURCE BLOCK to
AUTO mode
Design the FB Application correctly and download it to the
devices
• The Status received in input of the BKCAL_IN is BAD
Not Connected. Configure the link with the
downstream block
• The downstream block is producing a BAD status or
Not Invited. Check the reason on the downstream
block
Set the Target Mode to AUTO
• The Status received in input of the IN is BAD Not
Connected. Configure the link with the upstream
block
• The upstream block is producing a BAD status or
Not Invited. Check the reason on the upstream block
Set the Target Mode to CASCADE
• The Status received in input of the CAS_IN is BAD Not
Connected. Configure the link of the CAS_IN with
another block
• The upstream block is producing a BAD status or
Not Invited. Check the reason on the upstream block
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
