Automation & Control products allow the building of machines and systems that automate an industrial process, factory production, energy systems, buildings, campus or city system etc.

As with most technology, Automation & Control has evolved from simple beginnings and has developed over many years

    Some traditional methods to build Automation & Control systems.

  • PLCs (Programmanle Logic Controllers )
  • DSC ( Distributed Systems Controllers )
  • DIO ( Distributed I/O)
  • DC ( Dedicated Controllers such as PID )
  • Embedded Microprocessors.

These technologies do not have a software OS or Operating System. They are called OSless and are dedicated Automation & Control systems.

These are used for critical systems that can run stabily and if there is a software or hardware glitch, they will reboot or restart very rapidly.

New type of Automation Controllers

IIOT Linux Edge Controller-/Computers

PAC ( OSless -Programmable Automation Controllers )

A IIOT Controller/Computer simplifies Automation considerably by bring many technologies into one simple programmable system. Using modern methods, a IIOT Computer can link traditional technologies like PLCs and PACs, place sensors directly to databases and cloud systems.

More info

A PAC has all the advantages of a traditional PLC but adds a much broader and a very modern development environment and therefore allows the building of more advanced and complete systems and processes.

Fundamentally PACs can perform all types of math very rapidly, and by design have distributed control and IO, they are corporate network aware and since they can be linked to corporate computer systems directly, PACs understand all the other technologies that are in that arena, such as databases, web, email, ftp, TCP, clouds, local and remote wireless and more.

Automation & Control IO

The products used to build the I/O sections of Automation & Control are listed below.

Most manufacturers have a full compliment of IO blocks for their PACs, PLCs, DIO, DSC

However there are occassions when additional IO is required and these are listed under the categories

Data Acquisition

DAQ has evolved over the years and now hardened industrial

DAQ is a cross over technology, and is being used for Automation and Control with PLCs, PACs, Industrial Computers and Embedded Microprocessors.

Other Industrial Automation methods

  • Soft PLC using a PC ( Virtual PLC )
  • Industrial Computers with IO
  • Embedded Microprocessors

These other Industrial Automation methods do use a software OS or Operating System. They are called OS Automation & Control systems. These can not be used for critical systems as they do take time to reboot and recover.

Note :- Embedded Microprocessors are the fastest reboots and usually are safe for less critical systems as they do not use disk drives to start up from. They use Flash Memory both for programs and data storage.
