IRIS-Net
The Virtual Logic block is similar to the IO Logic block, but has no connection.
The keyword Value of the block is used instead of a connection. he keyword
Persistent is used for persistent storage of the value:
– Persistent = 1: The value is stored in non-volatile memory, so the value is
still available after a reset of the DPM.
– Persistent = 0: The value is stored in volatile memory.
The Constant Logic block is a constant parameter for Boolean values. The
block always outputs the value assigned to its keyword Value during Task
Engine configuration.
The Calendar Entry block is being used to create time-dependant Boolean
values. The outputted Boolean value depends on the configuration of this
block and the current system time.
ANALOG OPERATIONS
Element Description
The Addition block provides 2 inputs for rational numbers. The rational number at the output is always
the sum of rational numbers of the (wired) inputs.
The Subtraction block subtracts the rational number of the lower input from the rational number of the
upper input. The output always presents the result of this analog operation.
The Multiplication block multiplies the rational number of the upper input with the rational number of
the lower input. The output always presents the result of this analog operation.
The Division block divides the rational number of the upper input by the rational number of the lower
input.
CAUTION: If the rational number "0" is present at the lower input, the rational number "0" is always
output, independent of the upper input's value.
The Switch block switches the rational number at the center or lower input through, depending on the
Boolean value at the upper input. If the Boolean value at the upper input is false, the value of the
center input appears at the output. If the Boolean value at the upper input is true, the value of the
lower input appears at the output.
The Convert block converts a Boolean value to a rational number. The Boolean value 0 is converted to
the rational number 0.0, the Boolean value 1 is converted to the rational number 1.0.
The Equal block compares the rational numbers at the inputs. The Boolean value at the output is only
true when identical numbers are present at the inputs.
The Not Equal block compares the rational numbers at the inputs. The Boolean value at the output is
only true when the numbers that are present at the inputs differ from each other.
The Greater block compares the rational numbers at the inputs. The Boolean value at the output is only
true when the rational number of the upper input is greater than the rational number of the lower
input.
