MANIPULATED VALUE. At the output "Manipulated value",  
the effectively active manipulated value is read out in the 
floating point format. 

LMN_PER WORD  W#16#0000 

 

MANIPULATED 

VALUE PERIPHERY. The manipulated value 

in the periphery format is wired to the controller at the output 
of "Manipulated value periphery“. 

QLMN_HL

M 

BOOL FALSE 

  HIGH LIMIT OF MANIPULATED VALUE REACHED. The 

manipulated value is always limited to a high and low limit.  
The output  "High limit of manipulated value reached" signals 
that the high limit has been exceeded. 

QLMN_LL

M 

BOOL FALSE 

  LOW LIMIT OF MANIPULATED VALUE REACHED.  The 

manipulated value is always limited to a high and low limit.  
The output  "Low limit of manipulated value reached" signals 
that the low limit is underrange. 

LMN_P 

REAL 

0.0 

 

PROPORTIONALITY COMPONENT. The output  "P-
component" contains the proportional component of the 
manipulated variable. 

LMN_I 

REAL 

0.0 

 

INTEGRAL COMPONENT. The output "I-component“ 
contains the integral component of the manipulated variable. 

LMN_D 

REAL 

0.0 

 

DERIVATIVE COMPONENT.  The output "D-component" 
contains the derivative component of the manipulated 
variable. 

PV
