Honeywell VRX180 Batch Control, Initializing a disk, Filename Extensions Of Data Storage Types

Programming Function Blocks and Features

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.
