8. To Change the block from OOS mode to Auto mode click on the
AUTO buttons at the top of the window.
9. Close the Transducer block window.
The monitor window should now be displaying values with a
status of Good NonCascade.
10. If the AI has not changed to “Auto” mode, check to see that the
“Channel” and “L_type” have been initialized.
11. Double click on the offending AI block.
12. Under the Process Tab, look for Channel. This indicates which
of the channels through the Foundation Fieldbus device is
supported by this AI.
13. If the Channel is uninitalized, click on it and select one of the
available choices.
14. Click Write.
15. Go to the Scaling Tab.
16. Look at L_type, or Lineariztion Type.
17. If it is uninitialized, set it to Direct, and write the value. If you
still have problems with the device, call device manufacturer.
18. Squeeze the pressure ball on the transmitter or wait for a
pressure cycle and verify you can see the pressure change on
the monitor.
Now that the Fieldbus side is set up and working, you are ready
to configure the ControlNet side.
TIP
There is typically no reason for a Transducer
Block to be in the OOS mode, other than the
Configurator may not have been able to set it to
AUTO. Therefore, manually set it to AUTO. If
that is the only problem, the AI value will go to
AUTO, the status will change to GOOD, and you
will start to see data values from the transducer.
Also check the Resource Block. It should also be
in Auto Mode. If it is not attempt to manually set
it to Auto.
If the AI output does not go to AUTO, and the
Status to Good, you will probably need help
from the transmitter manufacturer.
