Problems when configuring function blocks
Transducer Blocks:
The operating mode
cannot be set to AUTO.
Check whether the operating mode of the Resource Block is set to AUTO →
MODE_BLK parameter group / TARGET parameter.

Incorrect parameterization
Make sure that the unit selected suits the process variable chosen in the
SENSOR_TYPE parameter. Otherwise the BLOCK_ERROR parameter displays
the "Block Configuration Error" error message. In this state, the operating
mode cannot be set to AUTO.
Analog Input function
block:
The operating mode
cannot be set to AUTO.
There can be several reasons for this. Check the following points one after
another:
1. Check whether the operating mode of the Analog Input function block is set to
AUTO: MODE_BLK parameter group / TARGET parameter.
If not and the mode cannot be changed to AUTO, first check the following points.
2. Make sure that the CHANNEL parameter (select process variable) has already
been configured in the Analog Input function block (→  33). The option
CHANNEL = 0 (uninitialized) is not valid.
3. Make sure that the XD_SCALE parameter group (input range, unit) has already
been configured in the Analog Input function block.
4. Make sure that the L_TYPE parameter (linearization type) has already been
configured in the Analog Input function block (→  33).
5. Check whether the operating mode of the Resource Block is set to AUTO.
MODE_BLK parameter group / TARGET parameter.
6. Make sure that the function blocks are correctly connected together and that
this system configuration has been sent to the fieldbus users, →  33.
Analog Input function
block:
Although the operating
mode is set to AUTO, the
status of the AI output
value OUT is "BAD" or
"UNCERTAIN".
Check whether an error is pending in the Transducer Block "Advanced Diagnostic":
Transducer Block "Adv. Diagnostic", "Actual Status Category" and "Actual Status
Number" parameters, →  39.
• Parameters cannot be
changed or
• No write access to
parameters.
1 Parameters that only show values or settings cannot be changed!
2. Hardware write protection is enabled → Disable write protection, →  26.

Write protection
You can check whether hardware write protection is enabled or disabled via
the WRITE_LOCK parameter in the Resource Block: LOCKED = write
protection enabled UNLOCKED = write protection disabled.
3. The block operating mode is set to the wrong mode. Certain parameters can
only be modified in the OOS (out of service) or MAN (manual) mode → Set the
operating mode of the block to the required mode → MODE_BLK parameter group.
4. The value entered is outside the specified input range for the parameter in
question: → Enter a suitable value → Increase the input range if necessary.
Transducer Blocks:
The manufacturer-specific
parameters are not visible.
The device description file (Device Description, DD) has not yet been loaded to the
host system or the configuration program? → Download the file to the
configuration system.
For information on where to obtain the DD,

Make sure you are using the system files for integrating field devices into
the host system.
Analog Input function
block:
The output value OUT is
not updated despite having
a valid "GOOD" status.
Simulation is active → Deactivate simulation by means of the SIMULATE
parameter group.

Other errors (application errors without messages)

occurred. Possible causes and remedial action, →  44.
