Troubleshooting
Problem Possible cause
The Target Mode is set to OOS
The Configuration Error bit is set in the
BLOCK_ERR
The Block cannot be
removed from OOS mode
The RESOURCE BLOCK is not in AUTO
mode
The Target Mode is not set to AUTO
The Simulation has been set with the
The Block cannot be
HW switch and the
switched in AUTO mode
SIMULATE_EN/DIS = Active
The OUT Status has the
Limit bits (0, 1) set to The Target Mode is not set to AUTO
Constant
The FEATURE_SEL has not the Reports
bit Set
Block Alarm Not Working LIM_NOTIFY value is less of the MAX_
(Events not notified) NOTIFY value
STATUS_OPTS has the Propagate Fault
Forward bit Set
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 %
– Enable IO_OTPS.Unit Conversion
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
