Understand Produced Network I/O
(also known as Network Outputs)
Under normal conditions, an I/O device produces the state of its
inputs and the status of any fault information on the device. However
with local logic running on a device, a master controller sometimes
needs to know the results of some intermediate state or value of logic.
Using a special I/O assembly containing network outputs, it is
possible for the device to report the state of any portion of the logic.
Each network output has a space reserved for it in the module’s
produced I/O assembly. When you connect this network output to
something in the logic, those results are reported in the produced
data.
In the following example, you can see when hardware inputs 0 and 1
are on at the same time. This is reported in Network Output 0.
Network Output 1 reports when Faults have occurred. Both of these
pieces of information are reported in the produced I/O data shown
below the example.
