Parameter Data
Type
Value Range Default Description
LMN REAL 0.0 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
