Diagnostic
Block_Err Possible Reasons
-
-
-
Block Configuration error
-
At least one of the inputs used in the Output calculation is not
usable**:
Input Failure/process
**For the inputs IN and IN_LO usable status are::
variable 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
Status of PV depends by the factor g. If it is less than 0,5 it will be used the Status of IN_LO otherwise it will use the Status of IN
The inputs with status byte different by GOOD are controlled by the INPUT_OPTS. The status of unused inputs is ignored.
The Status of the OUT will be the same of PV except when the PV is GOOD and the Status of the auxiliary inputs is NOT GOOD and
the INPUT_OPTS is not configured to use it. In this case the Status of the OUT is UNCERTAIN.
Otherwise the OUT Status id the worst of the inputs used in the calculation after applying the INPUT_OPTS
Troubleshooting
Problem
The Block cannot be removed
from OOS mode
The OUT Status is BAD
The OUT Status is UNCERTAIN
The OUT Status has the Limit
bits (0, 1) set to Constant
Block Alarm Not Working
(Events not notified)
ARITH_TYPE = 0 (uninitialized)
GAIN = 0
if COMP_HI_LIM =< COMP_LO_LIM and ARITH_TYPE in
the range 1-5
if BAL_TIME =< macrocycle and different by 0
GOOD_NC
GOOD_C
UNCERTAIN with INPUT_OPTION = Use uncertain
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
At least one of used inputs have a BAD status
At least one of the used inputs have an UNCERTAIN
status
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 worst Status of the used inputs
BAD + Out Of Service
Solution
Set the Target Mode to AUTO and/or remove the OOS
– Set the ARITH_TYPE with a valid value. It must be different by 0
and in the range 1 – 9
– Set the GAIN with value different by 0
– Set COMP_HI_LIM > COMP_LO_LIM when ARITH_TYPE in the
range 1-5
– Set BAL_TIME > of the Macrocycle IF 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
Check the upstream blocks
Check the upstream blocks
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
