H.11 Error handling
The flow meter publishes the error status on the Fieldbus
along with the real data. The error status can be seen in the
CH_x_Reported Error parameter on the Channel Transducer
Block. In addition, the Quality parameter shown with each of
the process variables reports the error. In Figure 139 below,
the CH1_REPORTED_ERROR shows as E1.
Note: For more information on the actual measurement
errors and possible causes, see Chapter 4, Error Codes and
Troubleshooting.
Figure 139: Reported error
Whenever the meter is in measurement error, the quality
bit for the published parameter shows bad quality (see
Figure 140 below). To change the quality bit to good, the
measurement error at the meter must be removed.
Notice the
QUALITY.STATUS field shows as Bad and the
SUBSTATUS field shows as Sensor Failure . This information
indicates a measurement error which must be corrected.

H.12 Simulation mode
Simulation mode allows the user to test the FF
implementation without the instrument providing real data.
The meter PCB is shipped with simulation mode disabled. To
enable simulation mode, complete the following steps:
CAUTION!
To prevent damage to the electronic
components, always use ESD protection
whenever handling printed circuit boards.
1. Remove the PCB from the meter.
2. Locate the jumper P5 (see Figure 141 below).
3. Move the P5 jumper to the left one place (pins 2 and 3)
to enable simulation mode.
4. Re-install the PCB into meter
5. Verify that the Block error field in the Resource Block
shows SimulationActive status.
