The connection to the publisher network variable can be done automatically. Select the publisher computer and select a variable. Name and datatype information is given by the publisher.
New inputs and outputs will appear beneath the network variable.
FrameState and FrameCtrl show the state/control of the received Ethernet frames. Both variables are reserved and not supported on the subscriber side.

Quality of Network variables
The quality of a network variable is shown on the subscriber side. Two inputs can be used. The variable quality shows a counter in 100µs resolution. The counter is incremented when the update of the variable is not in time. The sample shows the online quality variable after disconnection of the network plug for a while (counter is incremented) and plug in again (counter is zero).
The CycleIndex variable is incremented with each publisher cycle.
