Outstanding performance, flexible topology and simple configuration characterise EtherCAT Ethernet for control automation technologythe real-time Ethernet technology from Beckhoff. All types of Ethernet devices can be integrated via a switch or switch port. Where other real-time Ethernet approaches require special master or scanner cards, EtherCAT manages with very cost-effective standard Ethernet interface cards. In contrast to Bus Terminals, where the fieldbus protocol data is converted within the Bus Coupler to the internal, fieldbus-independent terminal bus, the EtherCAT protocol remains fully intact down to the individual terminal.

This ensures compatibility and continuity with the prevalent system. Existing and future investments are protected. Hannover Messe Technology studies on new communication topologies.

Status: In there, you can make an activeX coupling, which you can read and write through labview. This works fine, however its not particularly fast. So I'm looking for a labview ethercat driver I can use directly with LV, and of course I need to see a manual on how to send and read data.

Have you seen this? Also, this short article pointed out that I should couple the Twincat software to labview, this is something. If you go to NIs webpage and navigate to " DeveloperZone " search for "ethercat" and you find some more help like this page. I have a beckhoff PCI Ethernet card that is real-time, and has their drivers. Will this suffice? I have been told here you can find. I have no clue what else to do. You can build the EtherCAT network with the supported controllers.

The following is a typical EtherCAT network:. I was looking at 2 ways of hooking into TwinCAT's data.

LabVIEW SoftMotion 플러그-인 IndraDrive 설치운영 동영상

The first is activex, which is probably quite slow, as you mentioned. So I was looking around for some other method and I found this dll on Beckhoff's website, which I would assume, be much faster. It needs a license. I looked into this some more and successfully read data from an ethercat array through Beckhoff's TwinCAT. I used the examples found at:. I found both of these connections to respond very slow.

However, it's not really the connection's fault, it's the way the data is called and retrieved. The problem is that in all of these examples only 1 variable in TwinCAT can be addressed at a time. I have attached some example vi's.

They will be broken until you find "TcAdsDll. I have switched to their BK series fieldbuses that run on modbus. Still, I am looking to work with ethercat in the future, due to its faster response time and higher data traffic. I still don't understand why one would need NI realtime instruments before connecting to the fieldbus. If I have a realtime OS, or not even that, why cant I communicate through ethercat? Even if my demands are not certain response times ie realtime.

Was this information helpful? Not Helpful.But I cannot find any documentation on how to get the master set up on my PC. Go to Solution. The following two links should be able to provide more detailed information about the system requirements and the setup steps:.

Industrial Communications

Please refer to the Supported Hardware section in the link below for our recommended adapter list for real-time desktop target:. Thank you for those documents they are exactly what I was looking for. It's clear that I wasn't thinking about this problem correctly. Can someone give me some guidence.

I am able to talk Beckhoff Ethercat slaves using their TwinCat Software and a third party network card. Your question should be answered by what JZhou wrote earlier in this thread. CVI is not supported. So is it possible to communicate to any slave hardware irrespective of the manufacturer from my Master application. Because I want to develop a generic Master application which should communicate to different slaves of different manufacturer.

EtherCAT is an open standard and therefore you can use it with all slaves out there if they are compliant. United States. Industrial Communications. Turn on suggestions. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Are there any tutorials or instructions on how to do this? Message 1 of I've been working with Beckhoff hardware and I'm impressed, and I'm curious about how the TwinCAT software compares to LabVIEW as far as ease of use, stability and bugginess, and the power and flexibility of the programming languages available, that is how versatile it is compared to a compactRIO, where it seems you can do pretty much anything.

Thanks Rolf.

Configure EtherCAT Master to Interface with a Beckhoff EtherCAT Coupler

Fortunately I've gotten away from needing to deal with 5 different communication protocols to talk to random devices lately, as I've been able to control what hardware is used. How was that? I have only done minimal coding in TwinCAT.

Been involved on the side with such a project where we had to provide support to get a few NI EtherCAT chassis to work in a system with Beckhoff controllers, Bronkhorst Flow Controllers and several other devices. I was happy to sit on the side and watch them trying to get things eventually solved rather than getting my own hands dirty with TwinCAT programming.

Interesting, Beckhoff controller with NI hardware is the inverse of what I did. I really got shocked when I discovered how many more practically useful features the Beckhoff terminals and EtherCAT boxes have vs the NI C series modules and how cost effective they are.

Using the "EtherCAT box" modules eliminated large amounts of control panel wiring and harnessing, and still cheaper on a by module basis. We did indeed have some FPGA operation in there including some quadrature encoding and debounce circuitry. The main reason it was done with the NI chassis was however that they were already there from an earlier setup and it was considered to be cheaper to use them rather than buy Beckhoff IO terminals.

I would prefer a platform that allows me to use the language I already know and love. I can provide a PC application that implements anything the customer desires.

Finding the EtherCAT Slave XML File On My PC

If NI does not support the desired hardware i need to talk to, they have many other options like DLL calls and other ways of interfacing that I still have not found a specific limitation that I was not able to workaround to get the job done and still make the customer happy.

Yes, there are other languages and opportunities. They pretty much came up with the standard and are pushing it across the industrial world. It's just another communications standard. A lot of what NI implements is the basics of the industry standard. They rarely go above and beyond unless customers push for it. So they still can do better.Ethernet based bus systems spread very quickly at the moment.

The standard ethernet interfaces in any PC systems are not suitable adapter for this bus, because the reaction times of the Windows operating system do not meet the real-time requirements. The interface of the CIFX card can be used for all buses listed in the introduction, in many cases even as master or as slave. The configuration is done by the fact that the corresponding firmware in the map is loaded.

The appropriate firmware for this application is called cifxpnm. Figure 1: configuration utility by Hilscher device name and IP address.

The API of the map you can also, making the entire configuration from the application software out, which is much more complex and unnecessary, because the card stores all the settings until further notice. The actual communication between the CIFX card or will the drive automatically in the background, the map provides the user a process image available, the magnitude of which file defined by the GSDML is. Figure 5: VI to communicate with the LinMot drive.

For use as a master a paid license is required, the software of the master very much complex is, so a slave has the much tougher but generally its timing requirements, but it dominated just sure the card with an own processor.
