BAND(P),DBAND(P)

BIN 16-bit and 32-bit dead band controls (BAND(P),DBAND(P))

BAND(P),DBAND(P)

Function

(1) Controls the output value to be stored at the device designated by 

 by checking whether 

the input value (BIN 16 bits) designated by 

 is within the range of dead band upper and 

lower limit values specified 

by  

and  

or 

not.

Output value is controlled in the way shown below:

 • When 

 

   

 

  ..........

 

 - 

 

   

 

 • When 

 

   

 

   .........

 

 - 

 

   

 

 • When 

 

   

 

   

 

..... 0      

 

(2) The values that can be designated by 

, 

, and 

 are in the range of from  32768 to 

32767.

: Lower limit value of dead band (no output band) (BIN 16/32 bits)

: Upper limit value of dead band (no output band) (BIN 16/32 bits)

: Input value to be controlled by a dead band control (BIN 16/32 bits)

: Head number of the devices where the output value controlled by the dead band control will be stored 

(BIN 16/32 bits)
