I had a difficult time figuring out how to use TwinCAT motion the first time. I'll try to save you some trouble by writing a short?
Please let me know if something is unclear or incorrect, I'm also relatively new to this software but I'm always willing to learn from and fix my mistakes. To control an axis from within a POU Program Organizational Unitwe need to declare instances of the function blocks we'd like to use in the variable editor. Expand the PLC section and look for the References tab. Right click the References tab and select Add library Now that we've taken care of the dependencies, we can move on to the program itself.
Before we can start programming our system, we need to create a new PLC project to house all of our code. Choose Add New Item We're going to have to create a unique name for each function block we implement, so it's generally a good idea to make descriptive names. It also gives us access to the ReadStatus function.
Let's use ExAxName as the name of our function block. Let's also call ReadStatus on our new axis. ReadStatus into the Code Window. After adding those lines, our code should look something like this:. We'll call our new function block ExAxPower.
Beckhoff introduces CP6606-0001-0020 Panel PC
This is a necessity for any application, so let's add it to our program. We'll call our instance ExAxStop. When our axis encounters an error, and that's a guarantee, we will need to reset our axis to resume operation. Let's call our instance ExAxReset. I've only ever used Point To Point Motionso we will cover those. Each of the positioning function blocks is situational, so we can use whatever works best with our hardware.
For more information on any of the PTP Motion function blocks, navigate through the maze and find the point to point motion folder. State machines are simple and effective ways to control systems. There are two methods we will cover to develop a state machine. In the first method we will create Enumerations to give our states clear names.
In the second method we will simply use an integer variable to separate our states. The Enumeration method is more complicated but it is a worthwhile investment to improve the readability of our code. The integer state machine is great for quickly prototyping your project. We will cover both methods, but for the rest of the examples we will use the integer method.
Select Enumeration for the type and give it a descriptive name. Let's call ours ExampleStates.In addition, ultra-compact microSD flash memory cards are used as the storage media. Designed as a cabinet-mounted device in a fanless, space-saving format, the CP is ideal for use in PLC and small motion control applications that require compact, low-cost HMI hardware. When paired with TwinCAT runtime version 2 or 3the CP becomes a flexible automation controller for small and medium-sized machines, factories or buildings.
Microsoft Windows Embedded Compact 7 is offered as the operating system. The CP can also be used as an OPC UA client or server, greatly boosting the flexible connectivity and remote access capabilities of the device. All connectors are conveniently located at the back and bottom of the panel for easy accessibility.

What draws you to TwinCAT is its combination of low cost with a ton of features. They also provide an OPC server as an add-on if you need it. Switching software vendors is never easy. I had nothing but superb support from the local Beckhoff technical support guys during this experience.
North America tends to favor ladder logic, where Europe seems to favor instruction list, structured text, and function block diagram. It feels like the TwinCAT ladder logic editor was neglected a bit, but it is certainly workable.
Comparing the TwinCAT sequential function chart editor with the RSLogix sequential function chart editor, they were actually reasonably close. The Phoenix offering is worse and more expensive.

It hits a really unique sweet-spot on price, flexibility, and features that nobody else seems to be able to offer right now. So far my feelings are quite good in terms of performance and prices.
Angel: Great! In general, the HMI system is a bit lacking. Happily, the alarm system can be configured to automatically start a new log so the file size can be managed. I guess it should be noted that the HMI add-in from Beckhoff is rather basic, but does the job. Is is possible to customize Beckhoff products. If Yes, What all products can be customized and what will be the increase in price for an standard product and customized product. We concentrate in Home Automation applications, 1- so what you think does beckhoff have the required support for this kind of applications?
I prefer the more open architecture and technology of TwinCAT over more proprietary home automation systems where you have to buy everything from one vendor. No matter what you install, you need to protect it from intrusion.
I have gone in the opposite direction to you. I started working with Beckhoff and have now been forced to Siemens. I have to say I am definately missing the many features of the Beckhoff. Particularly the Scope. That was absolutely brilliant for tweaking the system and wringing every last ounce of performance out of it.
I would appreciate if you could help me about the communication between CX and CP.From TwinCAT 3. The TwinCAT 3 license can therefore also be used for hardware platform levels that are lower than specified when activating the license. TwinCAT 3 standard licenses are subject to a fee.
The license price depends on the hardware platform level. This can be very useful for commissioning or servicing. The trial licenses allow you to run quick tests and bridge the time period until full licenses are available.
The TwinCAT 3 development environment is required to create a trial license. See also: TwinCAT 3 test license. TwinCAT 3 volume licenses are usually preactivated. The aim of the volume licenses was to enable series machine builders with a large number of similar machines with identical TwinCAT 3 license configurations to use the volume licensing technology for easy handling of the licenses, since IPCs can be easily exchanged and licenses do not have to be activated by the user.
However, TwinCAT 3 license dongles now provide a much more flexible solution. Nowadays, a TwinCAT 3 volume license is therefore only useful in a few special cases. See also: TwinCAT 3 volume license.NETIndustrial Automation. In the world of programming there are a lot of PC programmers and comparatively few PLC programmers, but I inhabit a smaller niche.
This is a dangerous combination. The cost of design changes late in the project are so expensive that BDUF is the economical model. If you follow agile principles, your goal is to get minimal working software in front of the customer as soon as possible, and as often as possible, and your keep doing this until you run out of budget. People with electrical backgrounds tend to dislike the extra complexity that comes from the layers and layers of abstraction used in PC programming.
People from a PC programming background, however, tend to abhor the redundancy of PLC programs, not to mention the lack of good Separation of Concerns and for that matter, source control, but I digress.
The difference is that the reader, in the case of a PLC program, is likely to be someone with only an electrical background. Both electricians and electrical engineers can understand it. This includes the guy who happens to be on the night shift at 2 am when your code stops working, and he can understand it well enough to get the machine running again, saving the company thousands of dollars per minute.
On the other hand, PC programs are only ever read by other PC programmers. On the other hand, at JMP Engineeringvery few of us could do both, the rest specialized in one side or the other. In fact, I got the feeling that the pure PC programmers believed PLC programming was beneath them, and the people with the electrical backgrounds seemed to think PC programming was boring.
I also believe that innovation happens on the boundaries of well established disciplines, where two fields collide. All of their communication technologies are built around EtherCATan industrial fieldbus of their own invention that then became an open standard. Their PLC and motion controllers are real-time industrial controllers, but you can run them on commodity PC hardware.
As more and more automation cells need industrial PCs anyway, integrators who can deliver a solution that combines the various automation modules on a single industrial PC will be more competitive. NET languages, you can communicate between the. That means your system can now take advantage of tons of functionality in the.
NET framework, not to mention the huge amount of 3rd party libraries that can be pulled in. It would be pretty cool to auto-generate automation code, like ladder logic, from templates.
Plus, Visual Studio has integrated source control, but I digress…. Very interesting article. TwinCat 3 makes sense for future automation. And it all happens on the same, cheap machine! Not to mention they have indeed a huge range of terminals we have a student who is controlling a small light show trough DMX. Those applications are programmed the way it should be layers, models, controllers etc…. Communication with the plc happens trough the properties of a specific module. Very convenient.
We use a lot of Visual Studio and Twincat 2. It highlights the difference between North America and Europe. I wish I could buy Beckhoff stock! In switching to structured text I sometimes hear the protest that some people will not be able to understand the code, so I find it interesting that you bring up the mythological guy on the night shift who debugs the production line at 2 AM by going through ladder code.
Have you really found this to be the case? Some of the PLC controlled equipment we buy takes me, an experienced PLC programmer, days or weeks to become familiar with.Writing a tutorial like this was actually a learning experience for myself.
Before I made any statement about the software I tried to validate my assumptions first, and many times I learned that I had preconceived notions about how it worked which may not have been completely accurate. Write some code and run it. Thank you to everyone who offered feedback on the existing sections, and to those of you who kept pushing me to continue writing more. I sincerely hope this can be that missing link to take people from the world of traditional PLCs into the more interesting and ultimately more powerful world of PC-based control.
It looks like TwinCAT 3 has a viable future ahead of it. Interest seems to be growing over time according to Google Trends, anyway :. The recent drop in the world price of oil has caused a similar drop in the value of the Canadian dollar.
Much of that has to do with the huge oil production in Alberta, so that province is being hit particularly hard right now. The previous run-up in oil prices saw a lot of migration out of manufacturing-heavy Ontario westward to Alberta, and control system specialists were a big part of that. When rising oil prices drive up the Canadian dollar, it makes it a lot harder for Canadian manufacturers to compete in the export market, because their products are automatically more expensive.
The recent drop in the Canadian dollar, if it persists, is going to mean growth in the manufacturing sector, especially along the corridor in Ontario. Automation is poised to be a big part of the new growth in Ontario.
Technologies that can support flexibility are going to be winners. The PLC typically has to track things in memory like recipe data, part tracking, data collection, sequence numbers, machine counters, etc.
Will TwinCAT 3 be Accepted by Automation Programmers?
The other thing step 3 saves you from is simultaneous changes that were done online while you were busy making offline changes. I remember visiting a plant one time for a service call, and the local maintenance person was a bit suspicious of what I was going to do after all, I was a young kid who had never seen this machine before. The program is stored in local files on your hard drive and compiled into a TMC file.
The persistent data is stored in a different place on your hard drive. This makes offline changes go a lot more smoothly, of course. Since we also use Mercurial for version control, getting a copy of the latest program is a matter of pulling the latest from the source control, and copying it to the machine is a matter of pulling the offline changes to the machine.
I know that you can do an upload without uploading the memory. However, it seems like it requires you to download both the program and data at the same time. I wonder if anyone out there knows how to do better offline changes to a ControlLogix. If so, I would be interested to know that. Rather than being an introduction to PLCs, I assume most readers are coming to the new tutorial with some automation experience and they really want to know what this new technology can do for them.
As always I greatly appreciate any comments you have.
