6.1.1 Update-Update Use Case
Figure 47 shows an Update-Update use case. In this use case the input network variable of
the L-Proxy is bound to an output network variable of Node 1. This output network
variable is periodically updated. On the output side of L-Proxy the corresponding output
network variable is also bound to an input network variable on Node 2, which is waiting
for updates.

6.1.2 Poll-Poll Use Case
Figure 48 shows a Poll-Poll use case. In this use case the input network variable of
L-Proxy is bound to an output network variable of Node 1. However, this output network
variable on Node 1 is declared polled and never updated. Hence, Node 1 waits for
incoming polls. On the output side of L-Proxy the corresponding output network variable
is not bound. Node 2 periodically polls this network variable.

6.1.3 Update-Poll Use Case
Figure 49 shows an Update-Poll use case. In this use case the input network variable on
L-Proxy is bound to an output network variable on Node 1. This output network variable
on Node 1 is periodically updated. On the output side of L-Proxy the corresponding output
network variable is not bound. Node 2 periodically polls this network variable.

6.1.4 Poll-Update Use Case (Active Poll)
Figure 50 shows a Poll-Update use case. In this use case the input network variable on
L-Proxy is bound to an output network variable on Node 1. However, this output network
variable on Node 1 is declared polled and never updated; Node 1 waits for incoming polls.
On the output side of L-Proxy the corresponding output network variable is bound to an
