Modicon M340? Schneider Electric PLC

[yutagg]

I am an AB and AD programmer but my next project is working on a Schneider Electric/ Modicon M340, reworking and improving the logic. How screwed am I? No but seriously I was wondering how hard they are to work with compared to other brands. I also think i need (unity pro/ecostruxure) software, is there any specific version I should be looking to buy? Any advise is appreciated.

The latest version of the programming software is EcoStruxure Control Expert (formerly known as Unity Pro) 16.1. (specifically, you probably want Control expert classic [selected when you install 16.1], unless your project requires topology manager).

• If you have the project file as a STA (archive file, autosaved on download) you can open it with any version of the software equal to or greater than the version it was created in.
• If you have the project file as an STU (default file type) you have to open it with the same version.
• If you have a XEF or ZEF expert you can open it with almost any version of the software.
• If you don't have a project file, you can just connect to the PLC via USB, Modbus TCP, Modbus RTU, or whichever other protocol the specific CPU support and upload the program. 

YOu are probably in for a little learning curve:

• A DFB is the equivalent of an AOI
• an R_TRIG FB is the equivalent of a one shot
• A DDT is a custom data type enumeration (not sure what AB calls these)
• You can use all 5 IEC languages by default, no extra licenses required!

Ask here is you have more specific questions.

Transitioning to the Schneider Electric Modicon M340 from AB programming might initially seem challenging, but it's manageable! Here are some key points to help you get started:

Programming Language:
The Modicon M340 is recognized for its robust performance and flexibility. While it may present a slight learning curve compared to other brands—especially if you are accustomed to AB systems—many users find it intuitive once they become familiar with it. The Modicon M340 utilizes the IEC 61131-3 standard for programming, which includes languages such as Ladder Logic, Structured Text, and Function Block Diagram, similar to those you may already know.

Software Requirements:
To program the Modicon M340, you will need EcoStruxure Control Expert (previously known as Unity Pro). This software offers a comprehensive set of tools for programming, debugging, and maintaining your automation projects. The latest version includes all the new features you may need.

Tips for Transition:
Familiarize Yourself with the Software: Spend some time exploring EcoStruxure Control Expert. There are plenty of tutorials and resources available online to help you get started.
Leverage Community Support: The Schneider Electric Community and forums can be invaluable for troubleshooting and tips from other users.
Start Small: Begin with smaller, less critical parts of your project to build confidence before tackling more complex tasks.
