1010 0100 164 GOOD_NC
NOTE A: When the Transducer Block value goes outside the Range Limits, it should be Limited at the Range Limit high
or low, and the Status should be set to GOOD_NC- High Limited or Low Limited.
NOTE B: The XD_SCALE and/or OUT_SCALE can be set with EU0% value greater than EU100% value. In this case the
test of the OUT value with the range values is inverted.
NOTE C: This status can be set only if the specific AI Block_Err condition doesn't force the AI to OOS
Troubleshooting
Problem
The Block cannot be
removed from OOS mode
The Block cannot be
switched in AUTO mode
The OUT Status has the
Limit bits (0, 1) set to
Constant
Block Alarm Not Working
(Events not notified)
40 OI/266/FF/ADD-EN Rev. B | 2600T Series Pressure transmitters
Sub-Status
Unack advisory alarm
Unack critical alarm
Possible cause
The Target Mode is set to OOS
The Configuration Error bit is set in the
BLOCK_ERR
The RESOURCE BLOCK is not in
AUTO mode
The Target Mode is not set to AUTO
The Simulation has been set with the
HW switch and the
SIMULATE_EN/DIS = Active
The Target Mode is not set to AUTO
The FEATURE_SEL has not the
Reports bit Set
LIM_NOTIFY value is less of the MAX_
NOTIFY value
STATUS_OPTS has the Propagate
Fault Forward bit Set
Status_Opts
ACK_OPTION = clear
ACK_OPTION = clear
Solution
Set the Target Mode to something different by OOS
– Set the CHANNEL to a valid value different by 0
– Set L_TYPE = DIRECT – If XD_SCALE = OUT_SCALE
– Set LIN_TYPE = INDIRECT or IND.SQ ROOT – if XD_SCALE different by OUT_SCALE
– IF the AI_CHANNEL = 4 set the AI_LIN_TYPE = indirect
– IF the AI_CHANNEL = 4 set the XD_SCALE = 0 / 100 %
Set the Target Mode of the RESOURCE BLOCK to AUTO mode
Design the FB Application correctly and download it to the devices
The OUT_STATUS is produced as result of the normal calculation within the AI block but
starting from a simulated Status instead of the real TB Status
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
This bit should be cleared for producing the alarm
Descrition
The OUT_VALUE is outside the limits (HI_HI, HI, LO,
LO_LO) and the priority of the limits is between 3 and 7
The OUT_VALUE is outside the limits (HI_HI, HI, LO,
LO_LO) and the priority of the limits is between 8 and 15
