2. Programmable logic controller - Wikipedia

   en.wikipedia.org/wiki/Programmable_logic_controller

   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.

3. Ladder logic - Wikipedia

   en.wikipedia.org/wiki/Ladder_logic

   Part of a ladder diagram, including contacts and coils, compares, timers and monostable multivibrators Ladder logic is widely used to program PLCs, where sequential control of a process or manufacturing operation is required.

4. PLC technician - Wikipedia

   en.wikipedia.org/wiki/PLC_Technician

   PLC technician educational courses and programs integrate PLC programming with mechanics, electronics and process controls, They also commonly include coursework in hydraulics, pneumatics, robotics, DCS, SCADA, electrical circuits, electrical machinery and human-machine interfaces. Typical courses include math, communications, circuits, digital ...

5. SCADA - Wikipedia

   en.wikipedia.org/wiki/SCADA

   This allows SCADA system engineers to perform both the design and implementation of a program to be executed on an RTU or PLC. A programmable automation controller (PAC) is a compact controller that combines the features and capabilities of a PC-based control system with that of a typical PLC. PACs are deployed in SCADA systems to provide RTU ...

6. Sequential function chart - Wikipedia

   en.wikipedia.org/wiki/Sequential_function_chart

   Basic Batch SFC, with important elements labeled. Main components of SFC are: Steps with associated actions; Transitions with associated logic conditions; Directed links between steps and transitions. Steps in an SFC diagram can be active or inactive. Actions are only executed for active steps. A step can be active for one of two motives:

7. Industrial control system - Wikipedia

   en.wikipedia.org/wiki/Industrial_control_system

   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.
