Unpack
A0034314-EN
This unit unpacks the 8 bits of the octet value of its input port (8-bit unsigned integer) and writes
them to its Boolean output port.
XOr
A0034315-EN
This unit performs a binary Exclusive Or (Xor). The operation is performed in the largest integer data
type of all the output ports that are connected to the input ports of the unit. All the ports of the unit
adopt this data type. Input ports connected to floating point or string output ports are treated as if
they were connected to a 32-bit signed integer output port.

Input and output elements (I/Os)
There is one element for every input (I) and output (O). The number and structure of the
I/Os depend on the specific Fieldgate FXA42 device and its configuration.
Properties of the input and output elements:
• Every input or output element has a port - the value. The port can be connected to other
elements.
• The port
Val
represents the value of the input or output and has the same data type as
the input/output.
• The name of the interface, the device and the value are displayed in gray below the
element type.

A0034319
This element represents an array of inputs. In contrast to a plain
input
element, it can only be connected to an
output array
of the same data type
and size. The values of the inputs are read from the physical inputs during the
input stage of the IPO cycle.

element, it can only be connected to an
input array
of the same data type and
size. The values of the outputs are written to the physical outputs during the
output phase of the IPO cycle.
