PLC Articles – Software and Hardware

MixPlc

Since I started this blog in early 2011 I have written a lot of articles on PLCs. The PLC is a major part of many industrial facilities and machines, and indeed has been an important part of my career. Now that I am also teaching as well as designing and programming, I thought it might be useful to recap the articles on this site related to PLC Software and Hardware. It also might make them easier for some people in my classes to find.

I will be out of the country for a little over a week. When I return I have been asked to continue writing on some of these programming topics and will certainly try and do so; if you have a topic you would like me to cover, please let me know. As you can see, several of these articles were guest posts, mostly from other automation bloggers. If you would like to cover a topic, that would be awesome! I would especially like to hear from someone who works with Mitsubishi, GE, Omron, Modicon, ABB or Toshiba (Toyopuc).

Update March 2016: There is now a tab at the top of the Blog labeled “PLC”. This contains links to all of the PLC posts on this site.

    I want some technical discussions about how to send / receive data telegrams in step7 PLC program to / from a PC (running some kind of OPC Server) connected to the PLC with Ethernet Network. IP address of both the PLC and the PC is fixed and also the data block structure of send receive data telegram is known.
