6.11.2 Changing the fault timeout
By default, the transmitter immediately reports a fault when a fault is encountered. For specific faults,
you can configure the transmitter to delay reporting the fault by changing the fault timeout to a
non-zero value. If fault timeout is configured:
• During the fault timeout period, the transmitter continues to report its last valid measurement.
• The fault timeout applies only to the mA output and discrete output. Fault indication via digital
communications is unaffected.
The fault timeout is not applicable to all faults. See Table 6-5 for information about which faults are
affected by fault timeout.
6.12 Configuring digital communications
The digital communications parameters control how the transmitter will communicate using
Modbus/RS-485 protocol.
The following digital communications parameters can be configured:
• Fault indicator
• Modbus address
• RS-485 settings
• Floating-point byte order
• Additional communications response delay
6.12.1 Changing the digital communications fault indicator
The transmitter can indicate fault conditions using a digital communications fault indicator. Table 6-6
lists the options for the digital communications fault indicator.
Note: If an output is configured for valve control, the output will never go to fault levels.

Table 6-6 Digital communications fault indicators and values
Fault indicator options Fault output value
Upscale Process variables indicate the value is greater than the upper sensor limit. Totalizers
stop counting.
Downscale Process variables indicate the value is less than the lower sensor limit. Totalizers stop
counting.
Zero Flow rates go to the value that represents zero flow, and density and temperature
values are reported as zero. Totalizers stop counting.
