Beckhoff and TwinCAT 3 Programming Case Studies

Beckhoff Labview Driver

Oh an there are some that just read every post so that it is easier to find the unread posts. There were some issues with passing arrays between the two interfaces, but I was able to get it to work. Use this simple Serial Terminal application for command line access to your instruments. Do you have performance constraints for how fast you need to move data around or what the latency should be like?

Modbus is not a particularly fast protocol and its also not that easy to use there is only one data type. Most new industrial machines or retrofits require some form of connectivity to an existing communications infrastructure. Im glad, if someone has a hint or a sample program. It can also check for exceptions.

The latency period should be constant. Here are the screenshos of the two main vi's which I am using to make the eventing procedure.

Is there any other indirect solution? Another approach would be a multi-master system. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Then Main produces the handlers and all other stuff and the callback is responsible to bring the values into the application.

If you know that, you may be able to write your own driver. It was a hard task but now works very good with.

You can use communication gateways as needed to extend to more specialized protocols. Does anybody has any idea what should I try?

Sample code can be found here. You can use this to record current settings before performing a major change or to compare current values to the initial values an instrument had when it was shipped from our factory.

What type of hardware are you using exactly? Paste as plain text instead. On my testsystem i have tried it for many hours, but without any success.

Not sure which port your controller is connected to? That is before getting to propriety protocols. They will be able to give you definitive answers and may even allow you to use a card for a short period to see if it is suitable for your needs. Are there any other alternatives available? Display as a link instead.

If you don't need deterministic single-point data communication, intel lan driver for windows 7 does the beckhoff controller support other protocols? Swen Thank you for confirming that at least somebody used Beckhoff modules in some projects. The master system should be a Beckhoff control.

Throughput is about bytes per message. What kind of throughput do you need?

Are you having problems communicating with your Alicat devices? You could consider some sort of custom serial or parallel interface. WireWarrior Thank you for your reply. Any help or reply is much appreciated.
