Unity Pro & Modicon M340Developing your first project with Unity Pro


The purpose of this tutorial is to show you how easy it is to use Unity Pro by means of a practical application controlled by the Modicon M340 programmable logic controller (PLC).

The chosen application is a

conveyor belt that transports boxes to place them in batches of 10 on a

pallet.

Your first Unity Pro project Goals

Programming in LD Programming in ST To find out moreOn-line modification

Starting from an application specification of requirements, we are going to show you the project development principles using Unity Pro

The project will be debugged on the PLC simulator and then configured to run on the real PLC. Recorded demonstrations of the operating modes will also be proposed.

The project will be debugged on the PLC simulator and then configured to run on the real PLC. Recorded demonstrations of the operating modes will also be proposed.

The tutorial is divided into four parts:

1. Programming in LD (Ladder Diagram language): this part presents the method to be used to create a project, the programming procedures in LD, as well as project debugging.

2. Programming in ST (Structured Text language): this part presents the programming and debugging procedures in ST, as well as how to use the operator screens to view and control the process.

3. On-line modification: presents the procedures required for the on-line modification of the program.

4. To find out more: this last part of the tutorial shows how easy it is to integrate Modicon M340 PLC, programmed with Unity Pro, in an automation architecture: controlling an ATV31 variable speed drive, operator dialog with a Magelis XBT GT terminal.

Your first Unity Pro project Methodological approach


The installation we want to control is a conveyor belt that is used to transport boxes which are placed in batches of 10 on a pallet and then dispatched. An expression of requirements will be proposed for each function, as well as a development methodology.

The chosen application breaks down into three functions:

The Conveyor function which is used to control the conveyor belt.

The Palletizer function which is used to count the boxes and process a new pallet.

The Management function which makes it possible to stop the conveyor belt after a certain lapse of time, if there are no boxes left on the conveyor.

Unity Pro allows you to program the following PLCs: Modicon M340, Premium, Atrium, Quantum . The Project Browser visualizes the organization of the project and gives the access to the editors. The windows are repositionable on the screen and can be posted according to several modes (full page, reduced, floating)

Once you have finished keying in your program, we are going to Analyze the project (report the errors and warnings in the project) and then Rebuild All the project (essential the first time).

Remark

The PLC simulator allows you to simulate a project in its entirety with all the associated user tasks. However, the dynamics of the simulator's execution behavior cannot be compared with that of a real PLC.

Run the program on the simulator

You can run the project on : - the PLC, in which case you must define the configuration. - a PLC simulator, in which case it is not necessary to define the configuration.

When generating code, Unity Pro takes into account whether the target is the PLC or a simulator.

If the conveyor is running, the boxes are placed on the conveyor. The boxes are counted. When there are 10 boxes, the pallet is full and the blocker is activated. When requested by the operator, the pallet is removed so that a new one can be processed. The section will be programmed in Structured Text (ST) language. An operator screen is used to command process and view its status.

The upload information consists of the code, variable symbols, comments and

animation tables, etc. They are saved when you record the project and they may or may not be

included with the PLC memory.

This information makes it possible to work with a workstation that does not

contain the project.

This allows you to include, or not, the information that ensures link animation in contact language in the generated code.
