Encore — Configuration Manual 29
Overview
Figure 14. Applications, Engines, Clients, and Servers
The Client/Server architecture makes an Encore system scalable, from
small single purpose applications to huge facility wide installations. An
Encore system can even support multi-facility operations. Additions can be
made to an existing system by adding components without the need to re-
engineer the rest of the system hardware. Processing workloads can be dis-
tributed among various engines to prevent bottlenecks, and redundancy
can be incorporated for reliable operation.
System Communications During Normal Operation
When an operator presses a button on a control panel, a series of messages
are passed between client and server applications to accomplish the cros-
spoint change and to update button tallies on all the affected Panels
(
Figure 15 ). In this example the Panel Server application and the Router
Control applications reside on a separate engines. If they reside on the same
engine, similar communications occur.
