PLC Programming with C++ or C#

[Mohsen]

Hi everybody, I have some experience in PLC programming with Ladder and SFC languages but I didn't hear about PLC programming with C++ or C#. One of my customers asked me about that. does anybody have experience about it? If anybody have any link address or book please let me know about that. Thank you.

Generally speaking, PLCs aren't programmed in standard computer programming languages. Some PLCs allow programming in Structured Text, which is similar to computer programming, though it's usually a brand-specific variation. Embedded controllers, however, are a different story, but they aren't usually used for industrial applications. Here's a related thread: http://forums.mrplc.com/index.php?showtopic=25984

Mitsubishi does offer a C programmable CPU for the Q Series, but I have never seen one in use. Structured text is available in most IEC 61131-3compliant PLC brands. I know I have used structured text in Modicon, Mitsubishi, and Omron controls. It's very similar to C.

Thank you for taking time to answer me.

There are a few higher tech PLCs like B&R and Beckhoff that offer ANSI C programming standard. I know B&R also offers C++, but that is an add-on more geared for automatically generating code from MatLab/Simulink. ANSI C actually lends itself very well to PLC work, but C++ and C# start getting very object oriented which starts to veer away from the point of hard real time processing that PLCs normally do. That's why you don't typically see newer, high level, PC languages in industrial automation, they are geared around PC type operation with interrupts and events. PLC programs run all the way through, over and over, a completely different type of programming.

My background is a mix of electrical and IT software programming.Though,I have a experience in c++,C# and Java, I do not how exactly the software development will be in the automation field. I have a month time to prepare regarding the things I can learn. I have not got any reference or guidance online for a beginner programmer in the factory automation field. Any suggestions would be helpful.. achat housse samsung galaxy s6 etui samsung galaxy s6 folio Edited February 3, 2015 by gear-bored

Hi Mohsen,

Why don't you program using a PC based motion controller. One option is the RMP EtherCAT PC motion controller. The languages supported are C++, C#, and VB. NET. The API is called RapidCode, which is powerful and simple to use.
