Creating the Program
The Arduino OPTA PLC allows users to program it using the Arduino PLC IDE in Instruction List (IL) format. This is one of the industrial PLC languages, providing a simple and intuitive method for those accustomed to pneumonic programming. To create a program, users must open the Arduino PLC IDE software and select the option for a new project. After entering a project name, the user will be presented with a blank canvas to begin programming.
Programming the PLC
The programming language used for the Arduino OPTA PLC is based on the IEC standard, allowing users to create control programs that resemble simple pneumonic programming. This makes for an effective and efficient programming technique. To begin, users can start by programming the CPU LED to turn on when the program is running. This is done by setting the CPU LED as an output and then setting the output to “ON” when the program is running.
Adding Inputs and Outputs
The next step in programming the Arduino OPTA PLC is to add inputs and outputs. This is done by setting the input and output pins as either inputs or outputs. For example, if the user wants to turn on the first LED output when either input one or the CPU user button is pressed, they would set the input and output pins as inputs and outputs respectively. Then, they would set the output to “ON” when either input one or the CPU user button is pressed.
Testing the Program
Once the program is complete, it is important to test it to ensure that it is functioning correctly. This can be done by running the program and observing the output. If the program is functioning correctly, the CPU LED should turn on when the program is running and the first LED output should turn on when either input one or the CPU user button is pressed.
We can assign a variable to the button inputs that will be used in our instruction list program.
Mapping Physical IO
The Arduino OPTA PLC is equipped with physical inputs and outputs that must be mapped before they can be used in a project. To do this, the user must select the Resource tab at the bottom of the Workspace window. This will display all the physical inputs and outputs available on the controller.
Programmable Inputs
The Programmable Input Mapping will be displayed when the user selects this option. Here, they can assign a variable to each of the inputs they intend to use in their Instruction List (IL) program. Additionally, they can select whether the input is digital or analog, as well as the analog resolution.
Relay Outputs
The Relay Output Mapping will be displayed when the user selects this option. Here, they can assign a variable to the relays that will be used in their IL program.
LED Outputs
The LED Output Mapping will be displayed when the user selects this option. Here, they can assign a variable to the LED outputs that will be used in their IL program. These are the status lights on the OPTA CPU unit and can be used to indicate the state of the relays in the program.
Button Inputs
The Button Input Mapping will be displayed when the user selects this option. Here, they can assign a variable to the button inputs that will be used in their IL program. Additionally, the user can assign the Green Output to indicate that the OPTA PLC is scanning.
Once the user has completed the mapping process, they can begin programming their Instruction List (IL) program. This will involve creating a program file for the OPTA PLC and assigning instructions to each of the mapped inputs and outputs. The user can then save the program and upload it to the controller.
Mapping the User Button Music Input
In order to create an Arduino OPTA PLC program, the user button Music input must first be mapped. This is done by selecting the project tab in the main menu and then selecting the mapping tab. The user button Music input is then selected and the desired input is chosen from the drop-down menu. Once the mapping is complete, it can be saved using the icon on the main menu.
Creating the Program
Once the mapping is complete, the program can be created. This is done by selecting the project tab in the main menu and then selecting the program tab. The program can then be saved using the main menu file, save program. To access the task in the project, navigate to the project tab and locate the task folder. The tasks are categorized into fast, slow, background, and initializer. The fast task folder will execute the program cyclically, every 10 milliseconds (100 times per second). This can be changed by changing the set period to yes and entering a value in the period column in milliseconds. The majority of programs will be placed in this folder. The slow and background task folders will also scan cyclically. They are both set at a fixed period of 100 and 500 milliseconds (10 times per second and two times per second). These tasks are ideal for functions like math equations, etc. The init or initialized task folder sets variables or conditions in the PLC. After it powers up, it will run for one scan.
Starting a New Instruction List Program
To start a new instruction list program, select project new object, new program from the main menu. This will open a new window where the program can be created. The program can then be saved using the main menu file, save program. Once the program is saved, it can be executed using the main menu file, execute program. This will run the program in the PLC and the results can be seen in the output window.
Creating an Instruction List Program
Arduino OPTA PLCs offer users the ability to create programs using the Instruction List (IL) language. This language is based on the IEC 61131-3 standard and is a powerful, yet simple, way to program a PLC. To create an IL program, users can right-click on the project name and select the New Program option under the Add heading. This will open a new program window in the workspace.
Naming and Assigning the Program
The next step is to name the new program and assign it to the Fast Task folder. The program name cannot have any spaces. Once this is done, the new program will be displayed in the work area and will also appear as an IL symbol in the Help menu.
Programming the PLC
To begin programming the PLC, users can right-click in the Local Variable window of the workspace and select Insert. This will allow users to assign a Boolean variable, which in this example will be named Always On and have an initial value of one.
Using the Accumulator
When working with IL programming, users will always work with the accumulator. This is a special register that stores values and can be used to perform operations. To enter the program, users can use the IL reference. The first instruction is to Load Always On, which will load the accumulator with a value of one.
LED Output
The next instruction is to STL, which will store the LED output with a value of one, turning it on. This is used as an indication that the program is working. The next instruction is LD Button Input, which will load the accumulator with the value of the button. If the button is on, the value is one, and if it is off, the value is zero.
Logical OR Operation
The accumulator is then logically ORed with Input One and the result is stored back into the accumulator. The final instruction is ST Output One, which will store the output with the value of the accumulator. This completes the program and will turn the LED output on or off depending on the value of the button input.
Introduction to Arduino OPTA PLC
Arduino OPTA PLC is a programmable logic controller (PLC) that is designed to be used for industrial automation. It is a powerful tool that can be used to control and monitor various processes and systems. The PLC is programmed using an instruction list (IL) which is a set of instructions that are used to control the PLC. This article will discuss the basics of programming an Arduino OPTA PLC using an IL and provide an example of a first program.
Programming an Arduino OPTA PLC
Programming an Arduino OPTA PLC requires the use of an instruction list (IL). An IL is a set of instructions that are used to control the PLC. The instructions are written in a language called Ladder Logic which is a graphical language that is used to program PLCs. The IL is used to define the logic of the program and how the PLC will respond to certain inputs.
Creating an Instruction List Program
The first step in programming an Arduino OPTA PLC is to create an instruction list program. This can be done using the PLC IDE software which is a graphical programming environment for PLCs. The IDE allows the user to create an IL program by dragging and dropping instructions into the program window. The instructions can then be connected together to create a program that will control the PLC.
Downloading the Program to the PLC
Once the IL program has been created, it must be downloaded to the PLC. This can be done by using the Device Link Manager window in the PLC IDE. The Device Link Manager window allows the user to select the communication method with the PLC, enter the IP address of the PLC, and then download the program to the PLC.
Monitoring the Program
Once the program has been downloaded to the PLC, it can be monitored using the Watch window in the PLC IDE. The Watch window allows the user to enter and select variables or tags that they want to monitor. This allows the user to see how the program is responding to certain inputs and make changes as needed.
