Initializing Disk
Initialization activates storage and creates a file for each data set (Trends 1-3, alarms, events, unit data,
diagnostics). Filename extensions are as follows.
Trend 1 data
Trend 2 data
Trend 3 data
Alarms
Events
Unit Data
Diagnostics
Insert the disk. If you are using a 120MB/Zip disk, it is recommended you first preinitialize the disk with
DSU. Select INITIALIZE DISK from DATA STORAGE.
Select USE NEW SCHEDULES to store the new storage schedules. If you choose USE CURRENT
SCHEDULES, the disk is initialized using the current setup (the setup from the previous initialization), not
the new setup. Typically the operator will choose USE CURRENT SCHEDULES to continue storing the
same setup onto a new disk.
IMPORTANT
Initialization deletes any data already on the disk, therefore, you are prompted to press Enter to proceed or to
press Menu to abort.
When the INITIALIZING DISK message disappears, initialization has completed. If initialization fails, see
Table 6-8 for message descriptions.
