Operation
4.1 Getting started
The minimum configuration which has to be carried out in order to switch the Analog Input Block
from OOS (Out Of Service) to AUTO mode and to get a live measurement signal is as follows:
Analog Input Block (AI)
Please refer to chapter Analog Input Block (AI) for more detailed description of these
parameters.
If there are still problems to get started please execute a diagnosis as follows:
When looking to the parameter DIAGNOSIS_BLK at the Resource Block (RB) you can identify why
a block cannot be switched to AUTO mode or what has caused a Block Error. After solving the
issue the next diagnosis will be indicated in case of more than one cause.
Parameter Recommended setting Remarks
CHANNEL 1 = Volume Flow (e.g. l/h)
2 = Standard/Normal volume flow (e.g.
SCFH or Nl/h)
3 = Mass flow (e.g. kg/h)
Refer to EU (Engineering Units) on the
mechanical scale to determine the type
of flow
XD_SCALE 0 – Full Scale Follow mechanical scale respectively
values from TB (Transducer Block) for
Range and EU
OUT_SCALE 0 – Full Scale Follow mechanical scale respectively
values from TB (Transducer Block) for
Range and EU
L_TYPE Direct Linear function: Input = Output, same
