Configure Discrete Input Polarity
ProLink III
Device Tools > Configuration > I/O > Inputs > Discrete Input
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
.

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.
