Honeywell VRX180 Manual De Usuario

Data Storage can be started and stopped three ways.  At the highest level, the ENABLE STORAGE 
menu item enables or disables all data storage.  At the next highest level, EXTERNAL ENABLE enables 
or disables storage for each file type (Trends #1-3, Alarms, Events, Diagnostics, Unit Data).  At the 
lowest level, storage for each file type is started and stopped with one of two controls: a menu item 
BATCH STATE or a discrete parameter BATCH CONTROL. 

 

ENABLE 
STORAGE 

Acts as a master enable/disable switch for all data storage.  Select this item from the 
DATA STORAGE menu.  Set to ENABLE to allow storage of the current schedule.  If this 
is set to DISABLE, online data storage cannot take place, even if storage for 
individual files is enabled with EXTERNAL ENABLE. 

EXTERNAL 
ENABLE 

Acts as a enable (high)/disable (low) switch for each storage file type (trends, alarms, 
events, diagnostics, unit data).  Any storage file whose external enable is configured with 
a discrete will start and stop according to the state of that discrete.  This works 
independently of batch storage. 

BATCH 
STATE 

Acts as a start/stop switch for each storage file type.  The ENABLE STORAGE and 
EXTERNAL ENABLE both must be enabled for BATCH STATE to function. 

Accessed under DATA STORAGE menu.  If batch storage mode is configured for any 
storage file and if BATCH CONTROL has not been configured with a discrete, then you 
can manually start/stop the batches using this selection.  The instrument will automatically 
assign a number internally to identify the batch for storage.  For example, data stored 
between the first start and stop is marked as Batch #1.  When the next batch starts, the 
instrument will increment the batch number. These numbers identify the batches for later 
retrieval. 

BATCH 
CONTROL 

Accessed under SET UP NEW SCHEDULES.  If this item is configured with a discrete, it 
will start and stop storage for all storage files configured with batch storage mode.  The 
ENABLE STORAGE and EXTERNAL ENABLE both must be enabled for BATCH 
CONTROL to function.  The instrument will automatically assign a number internally to 
identify the batch for storage.  For example, data stored between the first start and stop is 
marked as Batch #1.  When the next batch starts, the instrument will increment the batch 
number. These numbers identify the batches for later retrieval. 

BATCH 
NUMBER 

Accessed under DATA STORAGE.  Shows the number (1-255) of the active batch. The 
batch number is assigned automatically by the instrument when the batch is started by 
either method (BATCH CONTROL or BATCH STATE).
