11.10.6 Status of the output value OUT
The status of the Analog Input Function Block and the validity of the output value OUT are relayed
to the downstream function blocks by means of the status of the OUT parameter group. The
following statuses can be displayed:
• GOOD_NON_CASCADE
The Analog Input Function Block is in the AUTO operating mode, i.e. the output value OUT is valid
and can be used for further processing.
•UNCERTAIN
The output value OUT can only be used for further processing to a limited extent. The
"UNCERTAIN" status signals to the downstream function blocks that a "notice message" is present
in the device, e.g. arising from active positive zero return or simulation.
•BAD
The output value OUT is not valid. The following causes are possible:
– The Analog Input Function Block is in the OOS operating mode.
– The Resource Block is in the OOS operating mode.
– The "BLOCK CONFIGURATION" status is displayed by means of the BLOCK_ERR parameter
(Page 40 ff.).
– A "fault message" is present in the device arising from a critical device error, e.g. an electronics
module defect.
!
Note!
In the Transducer Block "Diagnosis", the cause of the error message (notice/fault message) is
displayed via the "Diagnosis - Actual System Condition" parameter in the Transducer Block
"Diagnosis". A list of all the error messages, incl. remedial measures, can be found on Page 49 ff.
11.10.7 Simulation of input/output
Certain parameters of the Analog Input Function Block allow simulation of the input and output of
the function block:
1. Simulating the input of the Analog Input Function Block: The input value (measured value and
status) can be specified by means of the SIMULATE parameter group (Page 101). Since
the simulation value runs through the entire function block, all the parameter settings of the
block can be checked.
! Note!
If simulation is not enabled by means of the DIP switch (Page 35), the simulation mode
cannot be activated in the SIMULATE parameter (Page 101). The BLOCK_ERR
parameter (Page 88) in the Resource Block indicates whether simulation of the Analog
Input Function Block is possible.
2. Simulating the output of the Analog Input Function Block: Set the operating mode in the
MODE BLK parameter group (Page 87) to MAN and directly specify the desired output
value in the OUT parameter.
11.10.8 Diagnosis
Block errors and diagnosis information are displayed in the Analog Input Function Block via the
BLOCK_ERR parameter.

Input Function Block can be found on Page 46.
