Batch Control
Specify a discrete parameter as the START/STOP switch for all data types whose storage mode is set
to “BATCH”.
ATTENTION
If no BATCH CONTROL parameter is defined here, batch storage is started/stopped instead through the menu
item BATCH STATE. If a parameter is defined here, BATCH STATE menu item is disabled.
Initializing a disk
Select INITIALIZE DISK from DATA STORAGE. Initialization activates storage and creates a file for
each data set (Trends 1-4, alarms, events, unit data, diagnostics). Filename extensions are as follows.
Table 4-77 Filename Extensions Of Data Storage Types
Data set Extension
Trend data .LNT
Alarms .LNA
Events .LNE
Unit Data .LNU
Diagnostics .LND
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 6-6 for message descriptions.
ATTENTION
Refer to section 3.15 for additional information on disk initialization.
