PKDT Pack Date/Time. This function performs packing of 6 integers into a
Time/Date data type.
No
PULSER Pulser. This function block creates periodic pulse of defined ON and
OFF time-values. The ON and OFF time-values may be different.
RND Round. Half way values are rounded to the nearest even number
(Bankers rounding). The input value is a float. The result will be a
double; e.g. 5.5 rounds to 6, 6.5 rounds to 6, -5.5 rounds to -6, -6.5
rounds to -6.
No
RS Reset/Set. If Reset input is set to True, then the output is False. If Set
input is set to True and Reset input is False, then the output is True. If
both are False, then there is no change in the output. This gate is Reset
dominant bistable. If the Reset input is True, then the output is False,
regardless of the Set input.
No
RS-SIL SIL Reset/Set gate. The SIL Reset/Set gate operates the same as the
standard RS, but provides duplicate storage for the persistent value.
Yes
RTM Retentive Timer. This function block performs a Retentive On Timer
function. It provides a delay of time PT from the rising edge of input IN.
No
RTM-SIL SIL Retentive Timer. The SIL Retentive Timer operates the same as
the standard Retentive Timer, but provides duplicate storage for the
persistent values.
Yes
SCALE Scale. The input values can be integer, double or float. All the values
must be of the same type. The output will be of the same type. The first
value is the input. The second value is the low range for the input. The
third value is the high range for the input. The fourth value is the low
range for the output and the fifth value is the high range for the output.
No
SEL Selector. The True and False input values can be Boolean, integer,
double, string or float. They must be of the same type and the output
will be of this type. The selector input value is a Boolean. If the selector
is False, then the value at the False connection is passed to the output.
If the selector is True, then the value at the True connection is passed to
the output.
Yes for all but
floating-point
and string
values
SQR Square. The input value is a float. The result will be a float. No
SQRT Square Root. The input value is a float. The result will be a float. No
SR Set/Reset. This function block performs a Set-Reset function. If the
Set input is set to True, then the output is True. If the Reset input is set
to True and Set input is False, then the output is False. This gate is the
Set dominant bistable. If the Set input is True, then the output is True,
regardless of the Reset input.
No
SR-SIL SIL Set/Reset. The SIL Set/Reset gate operates the same as the
standard Set/Reset gate, but provides duplicate storage for the
persistent value.
Yes
