8.3 Configure a Frequency Output

Use a Frequency Output to report current values of process variables. The frequency varies between 0 Hz and
14500 Hz in proportion to the current value of the assigned process variable.
8.3.1 Configure Frequency Output Source
Display Menu → Configuration → Inputs/Outputs → Channel x → I/O Settings → Source
ProLink III Device Tools → Configuration → I/O → Outputs → Frequency Output x
Field Communicator Configure → Manual Setup → Inputs/Outputs → Channel x → Frequency Output x
Frequency Output Source specifies the process variable that is reported by the Frequency Output.
Important
Frequency Outputs on the 5700 transmitter are different from Frequency Outputs on previous Micro Motion
Coriolis transmitters:
• Frequency Output Source is not tied to the HART third variable. You can configure these independently.
Frequency Output Source can be configured independently for Frequency Output 1 and
•
Frequency Output 2.
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 Source as desired.
Defaults:
• Frequency Output 1: Mass Flow Rate
• Frequency Output 2: Mass Flow Rate
Postrequisites
If you change the configuration of Frequency Output Source, verify the Frequency Output scaling. The
transmitter automatically loads the most recent values for the scaling parameters, and they may not be
appropriate for your application.
