PlantStruxure high service functional unit5.4.1. Functional unit descriptionThe objective of the high service functional unit architecture is to propose a service drivenarchitecture providing a high level of service for process optimization, energy management, motorcontrol or advanced process control. It is an Ethernet based architecture – from process to fieldlevel. The main benefits of this architecture are the performance, the capabilities to use allEthernet based services, and the transparent data access using the routing capability thanks toembedded or external routers.The aim is to connect all motor control devices on Ethernet or through a Modbus gateway. A highdependability iPMCC uses this class of architecture in order to provide a high level of serviceduring the application life cycle. Instrumentation fieldbusses, such as Profibus PA, are also usedto deliver intelligent management of sensors or actuators.All ranges of PAC can be used to control a high service functional unit. Nevertheless, effectiveand flexible topologies can be proposed using Quantum Ethernet I/O solution.© 2012 Schneider Electric All Rights Reserved48
