    loraul10, I decided to place the array into a global variable lists and called that instead. This way, we can guarantee that the data is always available. I was really bummed out when I noticed this was not available. Hopefully, SP17 can address this and allow you to download text list from library without using Visu Manager

    Hello CoDeSys Enthusiasts, I would like to introduce a library called CoDeSys_EIP that I started working on roughly last Tuesday on my "spare" time. This library allows you to communicate with Rockwell PLCs using tag based communication. I decided to develop this library after trying to looking for this feature in CoDeSys without any luck and noticed that many folks asked for the same thin in a few different posts: https://forge.codesys.com/forge/talk/Runtime/thread/0e68f80e70/?limit=25#61cf Huge...

    Hey Folks, Any chatter on if CODESYS is going to release this variant of MQTT in their IIoT Library. Big hole in my opinion. Regards

    I think if you do a few searches on this forum you'll find a lot of answers. Starting with version 3.5.15.0 the softmotion license is only available as a seperate product that you need to pay for. If you want to use it for free you'll be restricted to version 3.5.14.40 of the library. The only PWM boards I know of with easy control from the Pi use I2C. You'd need to write something for a board that uses SPI if I2C won't be fast enough. The GPIO can not be configured as an interrupt. From what I've...

    I'm having some trouble with the serial communication. I am using raspberry pi on rasbian with V3.5.16.0. The com port appears to start properly, and I even notice some activity on the usb serial port (it is connected to an arduino), but all reads and writes appear to be empty (despite reporting successful). cat /dev/ttyACM0 lists no activity. If i start the arduino serial port monitor first, before initializing the com port in codesys, everything works perfectly. All activity shows up in cat /dev/ttyACM0...

    My understanding is that the MC_GearIn is only trying to sync the Master's velocity to the slave velocity. There will always be some error in the syncing of velocities, and therefore your positional error could build over time without correction. The advantage of the MC_GearInPos is that any positional discrepancy build would be automatically handled. Maybe I don't fully understand how the MC_GearIn works?

    Hello Codesys Community, When searching for term 'rt_preempt' there are past questions on the topic of reducing jitter on the Codesys Linux runtime, running on a Debian-based OS. I found these suggestions: Use of the RT_PREEMPT kernel patch Ensure stable CPU clock Use of CyclicTest tool for diagnostics To further improve performance (reduce jitter), are there additional suggestions from Codesys or the others in the community? For example: Debugging kernel latency Building a smaller/"lighter" kernel...
