Using Snapshots (VM Files)

Operational and data-logging information can be saved in 
“snapshots” (VM, virtual memory files). These snapshots 
let users view data, generate a report, and save or change 
setpoint configurations even when not connected to a 
control. To access the stored information,  “connect” to 
the snapshot instead of the physical control. Each control 
Setup disk includes a sample snapshot.

Saving Control Settings and Data to a 

Snapshot

Use the following procedure to save operational and data-
logging information:

STEP  1.  

Connect a computer to the control whose 
information is to be saved, and then start the 
IntelliLink software.

For details, see the “To Start the IntelliLink 

Software” section in Instruction Sheet 1011-530, 
“BankGuard Plus Control: 

Setup

.” If the com-

puter is already connected to the control, this 
step can be skipped.

STEP  2.  

From the 

File

 menu, choose the 

Save Snapshot 

option.

STEP  3.  

In the dialog box, specify a file name and location 
for this snapshot, and then click on the 

Save 

button.

If a location is not specified, the file is saved 

to the same directory as the program files for 
this for this type of control. The extension “.VM” 
is added automatically.

Viewing (Connect To) a Snapshot

Use the following procedure to view or connect to a 
snapshot:

STEP  1.  

Start the IntelliLink software on a computer. 
During startup, click on the 

Cancel 

button to 

close the Connect dialog box.

If the IntelliLink software is already run-

ning, choose the 

Disconnect 

option from the 

Connection

 menu, and then choose the 

Close 

Screenset

 option from the File menu to  clear 

the present screenset from memory.

STEP  2.  

From the 

File

 menu, choose the 

Open Snapshot

 

option.

The Open Controller Data File dialog box 

opens.

STEP  3.  

Select the snapshot desired to use, and then 
click on the 

Open

 button.

STEP  4.  

If the configuration settings in the snapshot are 
to be changed, click on the 

Yes 

button at the 

Connect to File dialog box. To avoid accidentally 
changing a setting, click on the 

No

 button.

The IntelliLink software opens and displays 

the contents of the selected snapshot.

Saving Changes Made to the Snapshot

All changes made to configuration settings in the snapshot 
are automatically saved to disk immediately. There is no 
need to “save” the changes in a separate operation.

Generating a Report From a Snapshot

Follow the same procedure used when connecting to a 
control. For details, see the “Generating Reports” section 
on page 15.

Creating a CFG File From a Snapshot

Complete the following procedure to prepare a setpoint 
configuration for a control in the field while not having 
access to a comparable device:

STEP  1.  

Connect to the snapshot.

For details, see the “Viewing (Connect To) a 

Snapshot” section.

STEP  2.  

Change the configuration settings in the 
snapshot as needed.

For details, see the “To Start the IntelliLink 

Software” section in Instruction Sheet 1011-530, 
“BankGuard Plus Control: 

Setup

.”

STEP  3.  

From the 

File 

menu, choose the 

Save Setpoints 

option.

STEP  4.  

In the Save Setpoints dialog box, specify a name 
and location for this configuration file, and then 
click on the 

Save 

button.

If a location is not specified, the file is saved 

to the same directory as the program files for 
this for this type of control. The extension 
“.CFG” is added automatically.

NOTICE

This process does not save the 

Location setting 

(on the 

Setup

 screen) or the 

Communications RTU 

Address setting (on page 1 of the 

Communications 

Setup

 screen) .
