Storing elaborated data 

 
E-Log stores the calculated statistical processings (elaborated data) in the 2-MB internal memory; a 
part of this memory (128 kB) is used for configuration information and other internal information; 
the real capacity is therefore slightly less than the total storage capacity. 
 
Data storage takes place circularly; once the memory is full, the new data will replace old ones. 
 
By  sending  a  new  configuration  to  the  instrument,  all  data  so  far  stored  will  be  cancelled;  this 
happens because the new configuration information might be potentially not in tune with them, and 
the PC might misinterpret them. 
 
The instrument stores the data in the internal memory only when a 

data page

 is full; the dimension 

of  this  page  equals  to  256  bytes;  therefore  the  instrument  might  store  the  data  only  after  several 
sequences of elaboration; this depends on the programmed elaboration rate, on the number of active 
measures  and,  for  each  one  of  them,  on  the  selected  elaboration  elements.  Please  note  that  by 
switching  off  the  instrument,  some  elaborated  data  inside  the 

data 

page  and  those  not  definitely 

stored might be lost; for this reason we advise transferring the elaborations which have not yet been 
transmitted to the PC before switching off E-Log. 
 
 

5.4.1

 

Memory autonomy 

 
Depending  on  the  chosen  configuration  (measures,  types  of  elaboration  for  each  measure  and 
acquisition rate) the instrument will work somewhat autonomously as far as the maximum storage 
time is concerned, without replacing old data with new ones. The calculation of the time dimension 
of the maximum number of storable data is as follows: 
 
A = K / (86400 / RE * NE) 
 
where: 
 
A =  number of days of autonomy of the data memory; 
K =  value subordinate on the size of the used memory; for the 2 MB internal memory, K=430592 

(from  2.12.00  instrument  firmware  version,  K=415744);  for  the  8  MB  internal  memory, 
K=1841152; 

RE = elaboration rate expressed in seconds; 
NE = total number of elaboration’s elements programmed for all measures.

Actuation logics 

 
E-Log has got an actuation logics library. It’s useful to switch-on all type devices (alarms, solenoid 
valves,  motors)  according  the  surveyed  parameters  in  surrounding  environment.  The  actuation 
logics are based on the instantaneous  value of the acquired and calculated measures. They  can be 
programmed  up  to  20  calculation  algorithms,  that  use  same  or  different  logics.  One  or  more 
algorithms can be combined in two differed modes , in order to switch-on the selected actuator:
