Configure Discrete Input Polarity

ProLink III
Field Communicator Configure > Manual Setup > Inputs/Outputs > Discrete Input > DI Polarity
Overview
The Discrete Input has two states: ON and OFF. Discrete Input Polarity controls how the
transmitter maps the incoming voltage level to the ON and OFF states.
Procedure
Set Discrete Input Polarity as desired.
The default setting is Active Low.
Options for Discrete Input Polarity

Configure events

An event occurs when the real-time value of a user-specified process variable moves past a
user-defined setpoint. Events are used to provide notification of process changes or to
perform specific transmitter actions if a process change occurs.
