Parameter Declaration Data Type Description
INT_HNEG INPUT BOOL INTEGRAL ACTION HOLD IN NEGATIVE DIRECTION
n The output of the integral action can be blocked in
a positive direction. To achieve this, the INT_HPOS
input must be set to TRUE. In a cascade control,
the INT_HPOS of the primary controller is intercon-
nected to QLMN_HLM of the secondary controller.
n Default: FALSE
SELECT INPUT BOOL SELECTION OF CALL PID AND PULSE GENERATOR
n If the pulse generator is activated, there are several
ways of calling the PID algorithm and pulse gener-
ator:
– SELECT = 0: The controller is called in a fast
cyclic interrupt level and the PID algorithm and
pulse generator are processed.
– SELECT = 1: The controller is called in OB1
and only the PID algorithm is processed.
– SELECT = 2: The controller is called in a fast
cyclic interrupt level and only the pulse gener-
ator is processed.
– SELECT = 3: The controller is called in a slow
cyclic interrupt level only the PID algorithm is
processed.
n Default: 0
n Range of Values: 0 ... 3
PV OUTPUT REAL PROCESS VARIABLE
n The effective process variable is output at the PV
output.
n Default: 0.0
n Range of Values: Dependent on the sensors used
LMN OUTPUT REAL MANIPULATED VALUE
n The effective value of the manipulated variable is
output in floating-point format at the LMN output.
n Default: 0.0
LMN_PER OUTPUT WORD MANIPULATED VALUE PERIPHERY
n The value of the manipulated variable in the periph-
eral format is connected to the controller at the
LMN_PER output.
n Default: 0
QPULSE OUTPUT BOOL QUTPUT PULSE SIGNAL
n The value of the manipulated variable is output
pulse duration modulated at the QPULSE output.
n Default: FALSE
QLMN_HLM OUTPUT BOOL HIGH LIMIT OF MANIPULATED VALUE REACHED
n The value of the manipulated variable is always
limited to an upper and lower limit. The
QLMN_HLM output indicates when the upper limit
is exceeded.
n Default: FALSE
