TwinCAT 3 can run on a plain-vanilla copy of Windows 7. Also, the license cost scales with the processing power of the PC. On the other hand, industrial PCs are hardened against tougher environmental conditions like dirt and temperature, and they come in nicer form factors for mounting inside of a control panel.
They also take a 24V input rather than running from the AC mains. Whatever you do, make sure you invest in a good UPS as well.
The performance is phenomenal compared to any other bus on the market today, including any other Ethernet-based technology, and even SERCOS. The price is also quite reasonable because the technology is based on commodity Ethernet hardware. Your mileage may vary. Replacing them with FC90xx cards from Beckhoff resolved our problems.

By default, variables in TwinCAT 3 are not persistent. If you restart the runtime, or your PC loses power, then when your PLC program restarts the variables will revert to their default state. This is fine for many situations we generally want our outputs to start in the off state anyway. However, we can declare a section to be persistent like this:.
You will now see an online view of this Global Variable List:. As you can see, both variables have been created in the PLC, and they have the values 5 and 3, respectively. In the Prepared value column, enter the values 10 and 6, like this:. As you can see, the values have changed. You will be asked to confirm:.
Click OK to restart in Run Mode. You will see the TwinCAT icon in the system tray briefly turn red, and then turn back to green. You can see that the persistent variable retained the value of 10 that we wrote to it, but the non-persistent variable reverted to the initialization value of 3 that we defined in the variable declaration.
The written value of 6 was lost. The sequence of when this happens is critical to understand to prevent you from losing your valuable persistent data.
When you shut down the TwinCAT 3 runtime, here is how it saves your variables:. The default port numbers start at Here are some ways that this can happen:. Even if you use a UPS to provide Windows enough time to do a clean shutdown, there are still many ways that you can lose your persistent data such as the UPS failing, the hard drive failing, or a runtime crash. Unless you can afford to lose the persistent data, you must do more to protect it. While your PLC program is running, the only up-to-date copy of your persistent data is the actual values of the variables in your PLC memory.
The persistent data file is only written when the runtime shuts down cleanly, and it deletes the persistent data file after reading it when the runtime restarts.
The first step in protecting your persistent data is to periodically write out the persistent data to disk while the program is running. You can manually instruct the runtime to write out the persistent data file from within the PLC program.
There are already 4 libraries referenced. These references were added when you created the project, and they provide some basic function blocks like timers, counters, and string functions. That will display the Add Library window:. Now click on the System node highlighted above to expand it so you can see the system libraries:. If you want to see a list of what is contained in a library, double-click on that library name in Solution Explorer and it will open the Library Manager window:.
Click on the name of the function block to display a picture of the block on the right side:. You can click on the Documentation tab above the picture of the block to see more detailed information about the inputs and outputs:. You will now see the empty SavePeristentVariables program in the ladder logic editor:. Declare the function block variable as a local variable of the program, like this:.That add-on is reasonably priced and offers basic functionality such as buttons, indicators, alarms, and more.
Since you can download a free version of Visual Studio from Microsoft called the Express Edition, or more recently Community Editionthis is an interesting way to add an HMI to your system without paying additional software costs. Additionally, unlike packaged HMI solutions with their pre-defined set of features. An application written in.TwinCAT 3 HMI Tutorial User Control example
NET or C in this short tutorial. There are so many excellent resources available online for learning VB. NET programming. If so, you probably already understand why using. NET to build your HMI would be a better alternative than paying for a 3rd party solution in your case, at least. NET sub-folder. Pick the version corresponding to the. Go ahead and do that now, then activate the configuration and go online so you can see the value of that variable. Assuming you have Visual Studio Express or better installed, open it and use the new project wizard to create a Windows Forms project.
Click OK. The new project wizard should have created a new form for you called Form1. Open that form in the forms editor, and drag a button from the Toolbox onto the form button1. When you click the button, it creates a new ADS client. You have to specify a port number.
I will be using Beckhoff PLCs. I am not sure how to go about the whole process. Also, should I rather go for a state machine module? However due to my scanty programming knowledge I'm not sure if I'll be able to cope up with programming a state machine.
Structured text would be easier to edit and understand, in my view. The advantage of a "true" PLC is that you'll be able to debug in realtime and watch and change all variables during active operation. But for a comparatively simple project I'd stick with an existing PLC. Those languages helps you to code in a very similar manner as the machine works electrically and if you have some notions of electricity you will find them quite simple and nicer.
The main difference between PLC programming and regular programming are the way PLCs works, as it's perfectly described on the link posted by Jacques de Hooge. Each PLC cycle or sweep has three steps:. A watchdog is monitoring the sweep to ensure it's executed on the sweep time ms usually and that the next sweep is started on its corresponding time slot.
If the sweep is not finished in the sweep time, it's reset to the beginning and may cause the CPU to be stopped. So the PLC works as a continuous loop with no end and a regular PC application has a begin and an end of the application. Have in mind that just by using SFC you have the state machine developed for you by Beckhoff and you only need to program in ST or whatever what to do in each step and how to transition from one step to another.

Each PLC cycle or sweep has three steps: Read all the process input signal. In Beckhoff, the variables obtained through industrial network communications are read transparently as if they were connected directly to the PLC. Those signals stays unchanged for the whole cycle.
Execute user code. Activate the output signals. Those signals will be kept constant for the whole next sweep without minding the actual value of the variable on that sweep.
