Introduction to PLC (Programmable Logic Controllers)

The course starts off with an introduction to programmable logic controllers, covering the basic knowledge of hardware and the types of connected peripheral devices. It then leads on to provide the delegates with knowledge of programming language and how the software and hardware interact.

This will be followed by electro pneumatic control and connecting PLCs via ip addressing. Content varies between Allen Bradley simulation, Siemens PLC hardware and wiring exercises.


  • Identify types of PLCs & understand logic functions
  • Identify IEC 61131 -3 program elements for contacts, coils, memory bit flags, timers, counters in Allen Bradley and Siemens
  • Create a simple ladder program with rung comments and I/O allocation names
  • Hardwire digital and analogue devices to a PLC such as proximity sensors, contactors, solenoid coils
  • Configuring systems to establish communication via direct connection or via a network
  • Create sequential programs
  • Electro pneumatic control
  • Search, fault find & edit programs

The above uses LOGO hardware
