Emerson Micro Motion 2500, Руководство по конфигурации и использованию

Страница: 119 / 238

The default setting is None .
Restrictions
• If mA Output Fault Action or Frequency Output Fault Action is set to None , Digital
Communications Fault Action should also be set to
None
. If you do not, the output will not report
actual process data, and this may result in measurement errors or unintended consequences for
your process.
• If you set Digital Communications Fault Action to NAN , you cannot set mA Output Fault Action or
Frequency Output Fault Action to
None
. If you try to do this, the transmitter will not accept the
configuration.
Options for Digital Communications Fault Action
Label
Description ProLink III Field Communicator
Upscale Upscale • Process variable values indicate that the val-
ue is greater than the upper sensor limit.
• Totalizers stop incrementing.
Downscale Downscale
• Process variable values indicate that the val-
ue is lower than the lower sensor limit.
• Totalizers stop incrementing.
Zero IntZero-All 0 • Flow rate variables go to the value that rep-
resents a flow rate of 0 (zero).
• Density is reported as
0
.
• Temperature is reported as
0 °C
, or the
equivalent if other units are used (e.g.,
32 °F
.
• Drive gain is reported as measured.
• Totalizers stop incrementing.
Not a Number Not-a-Number
• Process variables are reported as
IEEE
NAN
.
• Drive gain is reported as measured.
• Modbus scaled integers are reported as
Max
Int
.
• Totalizers stop incrementing.
Flow to Zero IntZero-Flow 0 • Flow rates are reported as
0
.
• Other process variables are reported as
measured.
• Totalizers stop incrementing.
None
None (default) • All process variables are reported as meas-
ured.
• Totalizers increment if they are running.
