4.6 Status of the output value OUT
The status of the OUT parameter group communicates the status of the Analog Input
function block and the validity of the output value OUT to the downstream function
blocks. 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 tells the downstream function blocks that a "notice message" is
present in the device, triggered by an active positive zero return or simulation, for
example.
• BAD
The output value OUT is invalid. The following are possible causes:
– The Analog Input function block is in the OOS operating mode.
– The “BLOCK CONFIG ERROR” status is displayed via the BLOCK_ERR parameter,
(see Page 170).
– The Transducer Block TRANSDUCER_CH1 (flow channel 1, base index 1200),
TRANSDUCER_ CH2 (flow channel 2, base index 1300) or TRANSDUCER_ TOT
(flow channel 1, base index 1550) is in the OOS operating mode. The Analog Input
function block can only process the input value of the Transducer Block in question
if the operating mode is set to AUTO.
– A “fault message” is present in the device which is triggered by a serious device
error, e.g. a faulty electronic module.

Note!
The reason for the error message in question (notice/fault message) is displayed in the
Transducer Block TRANSDUCER_DIAG (diagnosis, base index 1600) via the
“Diagnosis - Actual System Condition” parameter.
A list of all the error messages (including troubleshooting measures) is provided in the
Operating Instructions for PROline Prosonic Flow 93 FOUNDATION Fieldbus,
BA078D/06/en.
4.7 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 SIMULATE parameter group, (see Page 179), can be used to specify the input
value (measured value and status). Since the simulation value runs through the
entire function block, all the parameter settings of the block can be checked.
 Note!
If simulation is disabled by the jumper on the I/O board, the simulation mode cannot
be activated in the SIMULATE parameter, ( see Page 179). In the Resource Block,
the BLOCK_ERROR parameter, (see Page 92), 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 (see Page 177) to
MAN and specify the desired output value directly in the OUT parameter,
( see Page 177).
