Output Parameters
The following table contains the description of the output parameters for
SFB 41/FB41 "CONT_C."
Parameter Data Type Range of Values Default Description
LMN REAL 0.0 MANIPULATED VALUE
The effective manipulated value is output
in floating point format at the "manipulated
value" output.
LMN_PER WORD W#16#0000 MANIPULATED VALUE PERIPHERAL
The manipulated value in the I/O format is
connected to the controller at the
"manipulated value peripheral" output.
QLMN_HL
M
BOOL FALSE HIGH LIMIT OF MANIPULATED VALUE
REACHED
The manipulated value is always limited to
an upper and lower limit. The output "high
limit of manipulated value reached"
indicates that the upper limit has been
exceeded.
QLMN_LLM BOOL FALSE LOW LIMIT OF MANIPULATED VALUE
REACHED
The manipulated value is always limited to
an upper and lower limit. The output "low
limit of manipulated value reached"
indicates that the lower limit has been
exceeded.
LMN_P REAL 0.0 PROPORTIONAL COMPONENT
The "proportional component" output
contains the proportional component of the
manipulated variable.
LMN_I REAL 0.0 INTEGRAL COMPONENT
The "integral component" output contains
the integral component of the manipulated
value.
LMN_D REAL 0.0 DERIVATIVE COMPONENT
The "derivative component" output
contains the derivative component of the
manipulated value.
PV REAL 0.0 PROCESS VARIABLE
The effective process variable is output at
the "process variable" output.
ER REAL 0.0 ERROR SIGNAL
The effective error is output at the "error
signal" output.
