Analog Input fct. block: The
operating mode cannot be
set to AUTO.
(continued)
There may be several reasons for this. Check the following in sequence:
1. Check whether the operating mode of the Analog Input Function Block is in
AUTO mode
→
Parameter group MODE_BLK / parameter TARGET.
If not and the mode cannot be set to AUTO, first check the following.
2. Make sure that the CHANNEL parameter (selection process variable) is configured in
the Analog Input Function Block
→
ä
71. The selection CHANNEL = 0
(Uninitialized) is invalid.
3. Make sure that the XD_SCALE parameter group (input range, unit) is configured in the
Analog Input Function Block

71 (incl. configuration example)
"
Caution!
Make sure that the selected unit is suitable for the process variable selected in the
CHANNEL parameter. Otherwise the parameter BLOCK_ERROR will display the error
message "Block Configuration Error". In this status the block operating mode cannot be
set to AUTO.
Analog Input fct. block: The
operating mode cannot be
set to AUTO. 4. Make sure that the L_TYPE parameter (type of linearization) is already configured in
the Analog Input Function Block
→
ä
71.
"
Caution!
Make sure that with the type of linearization "Direct" the scaling of the parameter
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.

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 Blocks is set to AUTO
→
MODE_BLK parameter group / TARGET parameter.
Using the various CHANNEL parameters (
→
ä
77) set the Transducer Blocks to the
AUTO operating mode.
2. Check whether an error is pending in the "Diagnosis" Transducer Block
(base index: 1600)
→
"Diagnosis" Transducer Block (base index: 1600)
→
"Diag. .- Act.Sys.Condition" parameter.

Parameters cannot be
modified or no write access
to parameters. 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 whether
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 changed in the
OOS (out of service) or MAN (manual) mode
→
Set the operating mode of the block to the necessary mode
→
MODE_BLK
parameter group.
4. The value entered is outside the specified input range for the parameter in question:
→
Enter suitable value
→
Increase input range if necessary
5. Transducer Blocks: The programming level is not enabled
→
Enable by entering the
code in the "Access – Code" parameter or by means of the service code in the service
parameters.
