Some Colleges, such as George Brown College, offer an online PLC Technician program that uses simulation software, PLCLogix, to complete PLC lab projects and assignments. [5] Certification by accredited schools and third-party organizations can enhance employment opportunities and keep PLC technicians current and up-to-date.
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.
Compact PLC with 8 inputs and 4 outputs Modular PLC with EtherNet/IP module, discrete and analog I/O, with some slots being empty There are four types of mechanical design for PLC systems. A single box (also called a brick ) is a small programmable controller that fits all units and interfaces into one compact casing, although, typically ...
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 ...

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.
A simplified PAL device. The programmable elements (shown as a fuse) connect both the true and complemented inputs to the AND gates. These AND gates, also known as product terms, are ORed together to form a sum-of-products logic array.
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 ...
