3.2 MEASURED, CALCULATED, SPECIAL AND SERVICE PARAMETERS 

Special and service parameters are intended only for transmission using MODBUS interface  

(RS-485/RS-232). Special and service parameters are given in Table 3.4.  

Measured  and  calculated  parameters  the  values  of  which  are  displayed  on  LCD  display,  limits  of  their 

measurements and accuracy are given in Table 3.5. 

Parameter  values  can  be  transferred  to  PC  connected  to  one  of  the  UBZ  interfaces  (MODBUS,  RS-232). 

Parameter addresses are indicated in Table 3.5.

Index of the last fault in 
the fault logbook 

It varies from 0 to 49, increasing by one after recording 
another fault in the fault logbook. When the quantity of 
faults will reach 50, the count of faults will begin again 
from scratch.
