Configure Discrete Output Polarity - Emerson Micro Motion 5700 Configuration And Use Manual

Integrate the meter with the control system
Important
This table assumes that Discrete Output Polarity is set to Active High. If Discrete Output Polarity is set
to Active Low, reverse the voltage values.
Important
Actual flow direction interacts with Sensor Flow Direction Arrow to determine the flow direction that
the transmitter uses in processing. See the following table.
Table 8-4:

Overview
The discrete output has two states: ON (active, asserted) and OFF (inactive). Two different
voltages are used to represent these states. Discrete Output Polarity controls which
voltage represents which state.
Procedure
Set Discrete Output Polarity as desired.
• Default: Active High
