Setting examples with high and low word

 

 

For some controllers the value for the total measuring range must be converted to a high 
word and a low word. 
 

 

Standard setting 8192 units x 4096 revolutions: 

 

 

 

 
8192

 units x 4096 revolutions  

 

=> total measuring range 33 554 432 

 
 

total measuring range 33 554 432 in hex   => 0200 0000 hex 

 

high word 0200 hex in decimal  

 

=> 

512

 

 

low word 0000 hex in decimal  

 

=> 

 
 

200 units x 24 revolutions - enable scaling: 

 

 

 

 200 

units x 24 revolutions  

 

=> total measuring range 4800 

 
 

total measuring range 4800 in hex   => 0000 12C0 hex 

 

high word 0000 hex in decimal  

=> 

0

 

 

low word 12C0 hex in decimal  

=> 

4800 

 
 
 

200 units x 1 revolution - enable scaling: 

 
 

 

 

 
  200 

units x 1 revolution  

 

=> total measuring range 200 

 
 

 

total measuring range 200 in hex  

=> 0000 00C8 hex 

 

 

high word 0000 hex in decimal  

=> 

0

 

  low 

word

 

00C8

 

hex

 

in

 

decimal

    

=>
