Analog Input Fct. Block:
The operating mode cannot be
set to AUTO.
(continued)
4.
Make sure that the L_TYPE parameter (type of linearisation) is already configu-
red in the Analog Input Function Block
"
Caution!
Make sure that with the type of linearisation “Direct” the scaling of the parame-
ter group OUT_SCALE is identical to that of the parameter group XD_SCALE. If
set incorrectly the parameter BLOCK_ERROR will display the error message
“Block Configuration Error”. In this status the block operating mode cannot be
set to AUTO.
Configuration example
5.
Check whether the operating mode of the Resource Block is in AUTO mode
→
Parameter group MODE_BLK/parameter TARGET
6.
Make sure that the function blocks are correctly interconnected and that this
system configuration has been sent to the fieldbus station
→
Analog Input Function Block:
The operating mode is set to
AUTO but the status of the AI
output value OUT is “BAD” or
“UNCERTAIN”.
1.
Check whether the operating mode of the Transducer Block is set to AUTO
→
MODE_BLK parameter group / TARGET parameter.
2.
Check whether an error is present in the Transducer Block
→
Parameter “Un-
/Locking - Access Code”.
Error messages
– Parameters cannot be modi-
fied or
– No write access to parameter
1.
Parameters that only display values or settings cannot be modified!
2.
Hardware write protection is enabled
→
Deactivate the write protection
→
!
Note!
You can use the parameter WRITE_LOCK in the Resource Block to check whe-
ther hardware write protection is activated or deactivated:
LOCKED = write protection enabled (activated)
UNLOCKED = no write protection (deactivated)
3.
The block operating mode is wrong. Certain parameters can only be modified in
mode OOS (Out of Service) or MAN (MANual)
→
Set the operating mode of
the block to the required mode
→
Parameter group MODE_BLK.
4.
The value entered is outside the specified input range for the parameter in que-
stion:
→
Enter suitable value
→
Increase input range if necessary
5.
Transducer block: the programming level is locked
→
Unlock by entering code
in the “Un-/Locking - Access Code” parameter.
Transducer block:
The manufacturer-specific para-
meters are not visible.
The device description file (Device Description, DD) has not been loaded into the
host system or the configuration program
→
Load the file into the configuration
system.
Reference sources of the DD
Analog Input Function Block:
The output value OUT is not
updated despite having a valid
status.
Simulation is active
→
Deactivate simulation via parameter group
SIMULATE.

Error messages
Error messages in the FF configuration program
Error messages on the local display
▼
Other error (without error message)
Some other error has occurred.
