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 reason
– 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 Set the value of LIM_NOTIFY equal, at least, to 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 by 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 by 0 (uninitialized)
– Set SHED_OPT different by 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. Config-
ure 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
