Communication Network

The ACE3600 system network consists of RTUs communicating with one or more
computerized control centers and/or with other RTUs. Each control center is connected to
the communication network.
The system can be relatively simple, comprising several RTUs and one control center. It
can be modularly expanded to a more hierarchical system, where several sub-systems
(comprising intelligent RTUs and/or sub-centrals controlling their peripheral RTUs)
communicate with a central computer.
The communication network is flexible, enabling each RTU to communicate with
hierarchies above it (RTU-to-central), parallel to it (RTU-to-RTU), under it (another
RTU), and also relaying messages through it (when the RTU serves as a communication
node).
While the communication protocol allows for a complex hierarchical system structure, it
does not make it complicated. This is because most of the communication interactions are
transparent to the user, except in those cases where the communication is to be defined by
the ladder application. In such cases, you should perform simple programming operations
to configure the required application.
Each RTU may be configured to serve as a far-end terminal or as a regional center. The
RTU may function as a regional center either by definition or only after loss of
