4-24
DIO 1 Control
Displays the configuration for Channel 1 as either a discrete Input or Output.
Digital Input 1
Displays what digital input Channel 1 will be set to when the Control for
Channel 1 is set to Input.
Digital Output 1
Displays what digital output Channel 1 will be set to when the Control for
Channel 1 is set to Output.
DO 2
Configure the digital output value here. This controls the digital output from
the transmitter on terminals 16(+) and 20(-). There are four options that the
digital output can be configured for:
• Reverse Flow – The output will activate when the transmitter detects a
reverse flow condition.
• Zero Flow – The output will activate when a no flow condition is
detected.
• Transmitter Fault – The output will activate when a transmitter fault
condition is detected.
• Empty Pipe – The output will activate when the transmitter detects an
empty pipe condition.
• Flow Limit 1 – The output will activate when the transmitter measures a
flow rate that meets the conditions established for the Flow Limit 1
Alert.
• Flow Limit 2 – The output will activate when the transmitter measures a
flow rate that meets the conditions established for the Flow Limit 2
Alert.
• Diagnostic Status Alert – The output will activate when the transmitter
detects a condition that meets the configured criteria of the Diagnostic
Status Alert.
• Total Limit – The output will activate when the transmitter net total value
meets the conditions established for the Total Limit Alert.
Flow Limit 1
Configure the Parameters that will determine the criteria for activating a HART
alert if the measured flow rate falls within a set of configured criteria. This
functionality can be used for operating simple batching operations or
generating alerts when certain flow conditions are met. This parameter can be
configured as a discrete output if the transmitter was ordered with auxiliary
outputs enabled (option code AX), or if this functionality has been licensed in
the field.
