(Contd)
Analog Input function block:
The operating mode cannot
be set to AUTO.
Analog Input function block
The operating mode is set to
AUTO, but the status of the
AI output value OUT is
"BAD" or "UNCERTAIN".
4. Make sure that the L_TYPE parameter (type of linearisation) is already
configured in the Analog Input function block
"
Caution!
Make sure that with the "Direct" type of linearisation, the scaling and
the choice of unit of the OUT_SCALE parameter group is identical to
that of the XD_SCALE parameter group. If set incorrectly, the
BLOCK_ERROR parameter will display the error message "Block
Configuration Error". In this status, the block operating mode cannot
be set to AUTO.

1. Check whether the operating mode of the Transducer Blocks is in
→
AUTO mode MODE_BLK parameter group / TARGET parameter.
The following Transducer Blocks must be set to AUTO operating mode
when using the different CHANNEL parameters:
Transducer Block "TRANSDUCER_CH1" (base index 1200):
– CHANNEL 2 (volume flow channel 1)
– CHANNEL 21 (sound velocity channel 1)
– CHANNEL 23 (flow velocity channel 1)
– CHANNEL 30 (signal strength channel 1)
Transducer Block "TRANSDUCER_CH2" (base index 1300):
– CHANNEL 20 (volume flow channel 2)
– CHANNEL 22 (sound velocity channel 2)
– CHANNEL 24 (flow velocity channel 2)
– CHANNEL 31 (signal strength channel 2)
Transducer Blocks "TRANSDUCER_CH1" (base index 1200) and
"TRANSDUCER_CH2" (base index 1300):
– CHANNEL 25 (average volume flow)
– CHANNEL 26 (total volume flow)
– CHANNEL 27 (volume flow difference)
– CHANNEL 28 (average sound velocity)
– CHANNEL 29 (average flow velocity)
Transducer Block "TRANSDUCER_TOT" (base index 1550):
– CHANNEL 7 (totalizer 1)
– CHANNEL 8 (totalizer 2)
– CHANNEL 9 (totalizer 3)
2. Check whether an error is pending in the Transducer Block
"TRANSDUCER_DIAG" (base index 1600):
→
"Diagnosis - Actual System Condition" parameter.
