Configuration and Use Manual
MMI-20016855
Option Description
External The output is powered by an external power source.
6.2.2 Configure Frequency Output Process Variable
Display OFF-LINE MAINT → OFF-LINE CONFG → IO → FO
ProLink III Device Tools → Configuration → I/O → Outputs → Frequency Output
Field Communicator Configure → Manual Setup → Inputs/Outputs → Frequency Output
Frequency Output Process Variable controls the variable that is reported over the Frequency Output.
Prerequisites
If you plan to configure the output to report volume flow, ensure that you have set Volume Flow Type as
desired: Liquid or Gas Standard Volume.
If you plan to configure an output to report a concentration measurement process variable, ensure that the
concentration measurement application is configured so that the desired variable is available.
Procedure
Set Frequency Output Process Variable as desired.
The default setting is Mass Flow Rate.
Options for Frequency Output Process Variable
The transmitter provides a basic set of options for Frequency Output Process Variable, plus several
application-specific options. Different communications tools may use different labels for the options.
6.2.3 Configure Frequency Output Polarity
