The previous two steps allow the starter mode and motor control device type to be selected. It is now time to
build the nal architecture that allows all motor control devices to be connected to the PLC, HMI and SCADA
system.
As described above, the choice of architecture depends on the requested level of monitoring, metering and
diagnostics and also depends on how much consistency is required with the other parts of the system. Other
selection criteria such as cost and performance can also inuence the nal choice.

To illustrate this chapter and build the following chapters, an architecture example is provided.
The proposed architecture has been built using the following criteria:
Mixed solution of motor control devices b
Motor control solutions are from the simplest to most advanced in order to describe the various monitoring
and diagnostics capabilities in the following chapters.
Communication consistency in the global system b
A solution that fulls the requirements of the automatism (control and starting of pumps, put in parallel,
monitoring loads...) and management (consumption, operating time, preventive maintenance...) is provided.
Sub assembly modularity b
The designer must be able to re-use material and software for the realization of water treatment application.
These subsets must be able to be duplicated for other similar applications. In order to facilitate process
extension and reduce design cost, Advantys STB distributed IO islands must be used to communicate with
Motor starter and variable speed drive. Advantys STB can be connected to different eldbuses.
Evolution facility b
The solution must be easily expanded beyond the initial design, so that extensions can be carried out without
having to reconsider the architecture.
The table below summarises the different types of connections offered by the motor control devices.

Selecting architecture
For all intelligent motor control , both Modbus and Modbus TCP with an additional Transparent Ready
gateway can be proposed. CANopen is also supported by most devices.
