For example, the aerospace parts manufacturer Meggitt PLC has branded its own Industry 4.0 research project M4. [71] The discussion of how the shift to Industry 4.0, especially digitisation, will affect the labour market is being discussed in Germany under the topic of Work 4.0. [72]
Industry 4.0 is a project in the high-tech strategy of the German government that promotes the computerization of traditional industries such as manufacturing. The goal is the intelligent factory (Smart Factory) that is characterized by adaptability, resource efficiency , and ergonomics, as well as the integration of customers and business ...
DF-1 - used by Allen-Bradley ControlLogix, CompactLogix, PLC-5, SLC-500, and MicroLogix class devices; DNP3 - a protocol used to communicate by industrial control and utility SCADA systems; DirectNet – Koyo / Automation Direct proprietary, yet documented PLC interface; EtherCAT; Ethernet Global Data (EGD) – GE Fanuc PLCs (see also SRTP)
The improved design, analysis, and manufacture of products enabled by CAx has been beneficial for industry. [77] Information technology, together with industrial machinery and processes, can assist in the design, implementation, and monitoring of control systems. One example of an industrial control system is a programmable logic controller (PLC).
The history of the IIoT begins with the invention of the programmable logic controller (PLC) by Richard E. Morley in 1968, which was used by General Motors in their automatic transmission manufacturing division. [17] These PLCs allowed for fine control of individual elements in the manufacturing chain.
The PLC originated in the late 1960s in the automotive industry in the US and was designed to replace relay logic systems. [2] Before, control logic for manufacturing was mainly composed of relays, cam timers, drum sequencers, and dedicated closed-loop controllers.
A feedback control loop is directly controlled by the RTU or PLC, but the SCADA software monitors the overall performance of the loop. For example, a PLC may control the flow of cooling water through part of an industrial process to a set point level, but the SCADA system software will allow operators to change the set points for the flow.
The Common Industrial Protocol (CIP) is an industrial protocol for industrial automation applications. It is supported by ODVA.. Previously known as Control and Information Protocol, [1] CIP encompasses a comprehensive suite of messages and services for the collection of manufacturing automation applications – control, safety, synchronization, motion, configuration and information.
