In today’s processes, within the modern control system, DCSs, PLCs, SCADAs, field instruments, sensors and actuators must properly offer high degrees of performance, integration and modularity and guarantee efficiency, reliability and fast and easy interchangeability.
Thanks to the developments of electroinics and microprocessor technology - even on small-sized plants – there is an increased need to meet specifications and material requisitions based on system architectures based on distributed systems and subsystems, with the necessary implementation of sensors and smart actuators, which must integrate with modern communication and ICT technologies.
The modern control networks, used also on un-manned plants, identify in the actuators essential components which must integrate and properly communicate with higher hierarchies and contribute to the safety of people, environment and capital investments.
