4.26 Data Storage
Overview
Data Storage lets you store trends, unit data, alarms, events, and diagnostics in separate files on a floppy
disk for later analysis and review (replay). Data can be reviewed onscreen or on a PC with SDA data
analysis software. Setpoint Programs, instrument configurations and calibrations are not part of the Data
Storage feature.
Setup and configuration of Data Storage is described in this section; Online operation is described in
Section 7.4.

Setup procedure
Data Storage setup is performed Online to avoid interruption of current storage. The steps are described
briefly Table 4-70.
Step
1
Access DATA STORAGE Online. Insert a formatted 1.44MB or 120MB disk into the disk drive. If
necessary, format disk using FORMAT DISK (see page 179). See Opening/Closing the Front Bezel
in Section 3.6. Only 1.44MB floppy disks can be formatted on the instrument; 120MB disks must be
formatted on a PC.
2
Select ENABLE STORAGE. See Enable Storage below.
3
Select SET UP NEW SCHEDULES to specify storage data, mode, and other settings. See page
171.
4
Select STORAGE ALLOCATION to specify storage rates. See page 177.
5
Select WARNING LEVEL % to specify the capacity warning level. See page 179.
6
If using a 120MB/Zip disk, preinitialize the disk using DSU software. This will reduce intialization
time (step 7) dramatically from hours to minutes.
7
Select INITIALIZE DISK, then select USE NEW SCHEDULES to initialize the disk with the settings
you created in steps 3 and 4. See page 181.
Enable storage
Set to Enable to turn on storage. If Disabled, no storage will occur, regardless of any other settings.
