Programmable Logic Controllers (PLCs) are widely used devices controlling industrial machines and processes and many other diverse applications, requiring primarily, combinatorial logic and sequential control. The PLC is a hidden technology, little known by the general public and overlooked in academic historical studies of technology. The research reported in this thesis aims to address this lack of awareness. The thesis explores the development of sequential and combinatorial logic control… Expand
Programmable Logic Controllers and Direct Digital Controls in Buildings
The concept of programmable logic controller (PLC) originated over the last century that has revolutionised the industrial sector. In the last few decades PLC in the form of DDC has been commonlyExpand

Developments in industrial control languages - where next?
TLDR
The influence of standards on the development of software languages for industrial control systems is reviewed and the benefits of having re-usable code in the form of function blocks as proposed by the emerging standard IEC 61499 are considered. Expand
Programmable logic controllers versus personal computers for process control
It is proposed that Personal Computers (PCs) can be used effectively for the same industrial applications as Programmable Logic Controllers (PLCs). The basic concepts related to the operation of aExpand
