I have a C code for latency optimization that generates a dll file (compiled in developer 97). I am looking to adapt this file to interface with TwinCAT instead of its current Serial configuration. If anyone has experience with making this kind of modification, your assistance would be greatly appreciated.
Without access to the source code of the DLL or an understanding of its functionality, it is highly improbable.
I've had some experience working with TwinCAT and C code. You might have to change how the I/O is handled in your code because TwinCAT uses EtherCAT for communication. Check out Beckhoff's information system for TwinCAT 3. It has quite comprehensive information on C/C++ programming and interfacing with EtherCAT. I believe under 'Programming' there is a subtopic on 'Real-time programming in C++', which could be beneficial. Also, try to ensure your latency optimization will play nicely with TwinCAT's real-time environment.
Sounds like an interesting project. I would suggest removing or commenting out any function calls or variables related to your Serial implementation and replacing them with their TwinCAT equivalents. You will need to consult TwinCAT's API documentation to find corresponding functions. Depending on the complexity of your C code, you might also consider restructuring it to interact with TwinCAT's real-time capabilities. Always remember to back up your original DLL, just in case anything goes wrong. Good luck!
While I don't have hands-on experience with this particular transition, I have done similar adaptations. My suggestion would be to approach it stepwise. First, understand how TwinCAT interacts with DLLs- there are some handy resources on Beckhoff's website for this. Then see how your output functions are currently written- if they're serial output, you'll likely need to rewrite those to suit TwinCAT's system. I'd advise setting breakpoints early on to trace the program's progress and catch any issues promptly. Hope this helps and good luck!
It sounds like a great project! While I don't have direct experience with TwinCAT, I've heard that using the TwinCAT PLC's ADS protocol can help you bridge your DLL during integration. Make sure to check out TwinCAT's documentation on creating ADS interfaces, as it provides insights on how to link your existing functionalities with TwinCAT's architecture. If you run into specific issues, feel free to share snippets of your code or describe the challenges, and maybe we can brainstorm solutions together!
It sounds like an interesting project! I haven't personally worked with TwinCAT, but since it's designed for real-time control, you might want to explore the TwinCAT ADS (Automation Device Specification) interface for communication. You could wrap your DLL functions with ADS calls to send and receive data more efficiently. Make sure to also check TwinCAT's documentation for any specific requirements regarding DLL compatibility. Good luck, and I'm sure you'll figure it out!
