A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
In 1986, GE Fanuc Automation Corporation was jointly established in the US by FANUC and General Electric (GE). Under the joint venture company, three operating companies, GE Fanuc Automation North America, Inc., in the U.S., GE Fanuc Automation Europe S.A. in Luxembourg, and Fanuc GE Automation Asia Ltd. in Japan were established (the Asian company was established in 1987).
1980: GE introduces the first Ethernet-enabled protection relay, a device that detects faults in systems. 1986: GE and Fanuc combine to create GE Fanuc Automation Corporation, which manufactures programmable logic controllers—one of the fundamental buildings blocks of what's come to be known as the Industrial Internet of Things.
The company was founded in 1994 under the name 3S-Smart Software Solutions. It was renamed in 2018 and 2020 to Codesys Group / Codesys GmbH. Version 1.0 of CODESYS was released in 1994. Licenses of the CODESYS Development System are free of charge and can be installed legally without copy protection on further workstations.
The Embedded Wizard Studio is distributed by TARA Systems GmbH or its distributors as a per-developer license. The license consists of two parts: The Embedded Wizard Studio (i.e. the IDE), to develop graphical user interfaces (GUIs) on your Windows PC, and the Embedded Wizard Platform Package, which acts as an abstraction layer to the used embedded system, graphical subsystem and (RT)OS (if any).
Siemens SIMATIC S7-300 PLC CPU with three I/O modules attached. As with other programmable logic controllers, SIMATIC devices are intended to separate the control of a machine from the machine's direct operation, in a more lightweight and versatile manner than controls hard-wired for a specific machine. Early SIMATIC devices were transistor ...
Hardware and software features combine to render the operating system unusually secure for an operating system of its generation and class. Multics influenced the design of the hardware, with gate-oriented secure transfer-of-control instructions and a hardware-enforced system of security levels very similar to that of the famous Multics rings.
