Diagnostics
Data storage for Diagnostics is a complete log of all diagnostic messages. It includes the diagnostic code or
identifier message and its time and date of occurrence.
Setup is done with the following parameters: STORAGE MODE, ROLLOVER, EXTERNAL ENABLE,
SELECT FILENAME, DIAG SAMPLES. See Table 4-71 and Table 4-74 for descriptions.
Depending on your selections, data collection will begin when the first diagnostic occurs, or when the first
diagnostic occurs after a batch start occurs.
When calibration is executed, the record is time stamped and stored to the diagnostic file.
Unit Data
Values for up to 12 points (analog input, calculated value, discrete input, discrete output, totalizer, etc.) can
be sampled at user-definable intervals and stored on disk. The sample interval must be set by a schedule or
triggered by a discrete event. Prompts are described in Table 4-73.

Programming Function Blocks and Features
Definition
Continuous storage becomes active immediately upon
initialization. Batch storage is controlled by a discrete
parameter (see BATCH CONTROL, page 179) or by
start/stop batch menu item. Batch data may be started and
stopped several times in a single file until the file is full.
Batch start increments a batch number that is stored along
with the data. The batch number may be used for data
retrieval and analysis using SDA data analysis software.
ON COMMAND storage collects a single sample of data
whenever the EXTERNAL ENABLE discrete makes an off-
to-on transition. If this mode is used, then SET UP
SCHEDULE is ignored.
Copies the data point list already set up for a currently
active Unit Data display.
Enter up to 12 points.
Select ON to continue gathering and storing trend data after
the Unit data file becomes full. The new data will replace the
oldest data on the disk as it is collected. No warning will be
given.
Select OFF to stop trend storage when trend space
becomes full. A "DISK FULL" message will then appear.
Data is buffered until a new disk is inserted and initialized.
This discrete parameter will allow Unit data storage when
ON(1) and will stop Unit data storage when OFF(0). This
enable is independent of the storage mode; it does not
control batch start/stop.
