5 unusual facts about programmable logic controller


Active heave compensation

A control system, often PLC or computer based, then calculates how the active parts of the system are to react to the movement.

Deep fryer

Industrial enterprises producing deep-fried snack foods such as potato chips or pre-fried French fried potatoes use automated frying systems that consist mainly of the actual frying pan, a tube type heat exchanger to heat the frying oil, a filter, a circulation pump, a banana tank for fresh oil and the automation system, most often a PLC.

Digifold

A system using Siemens S7-200 PLC and Siemens Servo controllers was developed throughout the late 1990s, into the year 2000.

Programmable logic controller

One of the people who worked on that project was Dick Morley, who is considered to be the "father" of the PLC.

Synchronous condenser

A PLC based controller with PF controller and regulator will allow the system to be set to meet a given power factor or can be set to produce a specified amount of reactive power.


Modbus

Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs).

RS-232

Additionally, modern industrial automation equipment, such as PLCs, VFDs, servo drives, and CNC equipment are programmable via RS-232.
