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.
code or identifier message and its time and date of occurrence.
Setup is done with the following parameters: STORAGE MODE, ROLLOVER, DIAG SAMPLES,
EXTERNAL ENABLE, SELECT FILENAME. See Table 4-72 for descriptions.
EXTERNAL ENABLE, SELECT FILENAME. See Table 4-72 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.
first diagnostic occurs after a batch start occurs.
When calibration is executed, the record is time stamped and stored to the diagnostic file.
The number of samples which can be stored on a disk (DIAG SAMPLES) can be up to 1600.
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 floppy disk. The sample interval must be set
by a schedule or triggered by a discrete event. Prompts are described in Table 4-74.

Continuous storage becomes active immediately upon
initialization. Batch storage is controlled by a discrete
parameter (see BATCH CONTROL, page 174) 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.

OFF, discrete parameter, 0, 1 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.
