5. Functions
This chapter describes each function of the product. The overview of each function is as follows.
NOTE
FOUNDATION Fieldbus items found in the following menu path tables indicate a case where
FieldMate,YokogawaElectric’sadjustingandsettingtoolforelddevice/environmentaldevice,is
used.
NOTE
For various setting changes, there is a mode which allows each parameter to be written.
Fordetails,referto“A1.2SettingandChangeofBasicParameters”.
If the parameter cannot be rewritten, check for write mode columns in parameter lists in Chapter
6.

each process value.
For details about how to check measured results and the setting procedures, refer to Section 5.1.
Totalization function
Two totalizers are mounted to totalize selected process values. In addition to the totalized value
display function, the product has a totalization counter function to scale totalized values with the
conversionfactorandtocountaspecicowrate.Theproductalsohasthetotalizationswitch

For details about the totalization function and setting procedures, refer to Section 5.2.
Limit switch function
This is the function to transmit 0 and 1 as a parameter by judging whether the selected process
value is above or below the threshold.
For details about each output and the setting procedures, refer to Section 5.3.
Inputting external temperature
Asatemperaturevalueforthetemperaturecorrectionofthemassowrate,atemperaturevalue
can be imported from an external device.
For details about inputting external temperature, refer to Section 5.4.
Auxiliary calculation function
This function is used to calculate the temperature correction for density or the calorie by inputting
thetemperaturefromanexternaldevice.Theaccuracyofmassowratemeasurementis
improved with the temperature correction for density.
For details about the auxiliary calculation function, refer to Section 5.5.
