TheField Layerhandles data communications between sensors, actuators, PLCs and RTUs. The network may be wired or wireless, using common protocols such as Modbus and Profibus. At theSupervisory Layer, the control network connects the RTUs and PLCs with the backend control systems using terminals su...
A Distributed Control System (DCS) is a type of automated industrial control system (ICS) used to control geographically distributed processes, such as those in factories, power plants, and other large industrial settings. DCS systems rely on a network of controllers distributed across a facility, ...
However, Fieldbus is not a connection type, per se, but instead, a description used to indicate a group of protocols. There are several protocols in the group such as ControlNet in the Allen Bradley family,Modbus, Profibus, EtherCAT,HART, CIP, and many more. A primary benefit of Fieldbus ...
They can be compatible with common industrial communication protocols such as Modbus, Profibus, and DNP3. Additionally, they can utilize Ethernet, serial communication (such as RS-232, RS-485), and wireless communication technologies. RTUs are usually designed to operate in rugged and industrial ...
PLCs serve as communication gateways between field devices and the rest of the SCADA system. PLCs may use common communication protocols such as Modbus, Profibus, Ethernet/IP,MQTT, orOPCto exchange data with other devices on the network. ...
Modbus SmartWire-DT DeviceNet IO-Link Ethernet Profibus Varan There are so many Fieldbus variant solutions available because the manufacturers of automation equipment developed proprietary Fieldbuses with differing features and functions to best deal with their market niche and to compete with each other...
The intrinsically safe aspect of thisarchitectureis particularly suitable for devices located in dangerous environments because it limits the power going to the field. This eliminates the need for the traditional containment method used by Modbus. ...
