Input Only Connections
When you use input only connections, you can create more than one
Class 1 scanner connection to the GuardPLC controller, specifying the
same input assembly instance. The GuardPLC controller specifies the
same multicast address for input data to all scanners asking for the
same input assembly instance. The GuardPLC controller only
produces the data once and all scanners receive the same input data.
No output data will go from the scanners to the GuardPLC controller.
All input only connections are independent from each other. When
one of them times out, the others remain active.
