Method and Parameter
The terms Method and Parameter referenced in the table below follow the same meaning as applied
used with device descriptions. Specifically,
Parameter:
The value of the parameter presented to the user. If the parameter can be modified
(i.e., the parameter’s handling allows it), then the user can modify its value. There is a
dependency with an input parameters entered.
Method:
Methods interact with the field device and the user to perform a consistent and
repeatable execution of a SOP (Standard Operating Procedure). Method can be defined by two
scenarios: one is to show multiple data in one single line or second is to get the output data.
8.2.2 PV Tracking Diagnostics
The below table provides diagnostic details related to process variable tracking such as high / low
value recorded and retention of the record into Non-Volatile Memory (NVM) of the transmitter.
The
table lists the methods to configure the limits for tracking PV Low and High values and methods to
read the diagnostic parameter values.

– PV Tracking
PV - High or
Low Values
PV Low Value
Method
Description
“PV Low Value” method will give
the details of Minimum PV value
that the device has experienced,
in user selected units along with
time stamp
Set-up
None. Value initialized to
PV
value prior to leaving the
factory. Updates with current PV
automatically when powered at
installation location after one
minute.
NVM*
Update after every 7.5 hours.
PV High Value Method
Description
T
he “PV High Value” method will
give the details of Maximum PV
value that the device has
experienced, in user selected
units along with time stamp.
Set-up
None. Value initialized to PV
value prior to leaving the
factory. Updates with current PV
automatically when powered at
installation location after one
minute.
NVM
Update after every 7.5 hours
