   PLC courses are usually full-time, and run for one or two years. They generally focus on practical work, academic basics, and work experience in a relevant industry. . Courses (major awards) are usually composed of eight or more component awards (or 'modules'), which add up to at least 120 FET credits; award codes beginning with 5M or 6M designate major awards (for example, 5M2102 Business ...

   en.wikipedia.org/wiki/Sequential_function_chart

   Sequential function chart (SFC) is a visual programming language used for programmable logic controllers (PLCs). It is one of the five languages defined by IEC 61131-3 standard.

6. 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 ...

7. Ladder logic - Wikipedia

   Note: In this example, "Run" represents the status of a bit in the PLC, while "Motor" represents the actual output to the real-world relay that closes the motor's real-world circuit. For safety reasons, an emergency stop ("ES") may be hardwired in series with the "Start" switch, and the relay logic should reflect this.
