Input Parameters
The following table contains the description of the input parameters for
SFB 42/FB 42 "CONT_S."
Parameter Data Type Values Default Description
COM_RST BOOL FALSE COMPLETE RESTART
The block has an initialization routine that is
processed when the input COM_RST is set.
LMNR_HS BOOL FALSE HIGH LIMIT OF POSITION FEEDBACK
SIGNAL
The "actuator at upper limit stop" signal is
connected to the "high limit of position
feedback
signal" input. LMNR_HS=TRUE means the
actuator is at upper limit stop.
LMNR_LS BOOL FALSE LOW LIMIT OF POSITION FEEDBACK
SIGNAL
The "actuator at lower limit stop" signal is
connected to the "low limit of position
feedback
signal" input. LMNR_LS=TRUE means the
actuator is at lower limit stop.
LMNS_ON BOOL TRUE MANUAL ACTUATING SIGNALS ON
The actuating signal processing is switched
to
manual at the "manual actuating signals on"
input.
LMNUP BOOL FALSE ACTUATING SIGNALS UP
With manual actuating value signals, the
output
signal QLMNUP is set at the input "actuating
signals up."
LMNDN BOOL FALSE ACTUATING SIGNALS DOWN
With manual actuating value signals, the
output
signal QLMNDN is set at the input "actuating
signals down."
PVPER_ON BOOL FALSE PROCESS VARIABLE PERIPHERAL ON
If the process variable is read in from the
I/Os,
the input PV_PER must be connected to the
I/Os
and the input "process variable peripheral on"
must be set.
CYCLE TIME >= 1ms T#1s SAMPLING TIME
The time between the block calls must be
constant. The "sampling time" input specifies
the
time between block calls.
SP_INT REAL -100.0 ...
+100.0 (%)
or phys. value 1)
0.0 INTERNAL SETPOINT
The "internal setpoint" input is used to specify
a
setpoint.
