  1. Hi Ausman, Sorry for the mishandling of the page I did not want to report your comment. I reported it without realizing it, I'm very sorry. I was asking him how to do the communication work first on the PC. Sorry mr Ausman😔
  2. Hello, thank you very much for your prompt response Gentlemen. I want to thank AlexUT for providing the correct MAYEKAWA CP IV controller manual. According to wiring it should be like the first image: The data flow should be as follows but I am not very clear about this form of data flow, could you explain to me how to do it? The number references should be the following, but I have called them decimal or hexadecimal but without success. If you want to see the manual I will leave it here, again thanking AlexUT. 488091769_MayekavaMYPRO-CPIV_Manual-pdf-free.pdf
  3. Hi Joe T, thanks for your quick response. The MAYEKAWA processor manual link is here https://qdoc.tips/cp4-mycom-manual-pdf-free.html. According to the document, it is possible, but I get an error when doing the holding registers.
  4. Hi everyone. I have tried to communicate with a MYCOM compressor that has a MAYEKAWA controller which in the manual says that it allows RS485 communication, I have been trying for 3 days without success. The MAYEKAWA controller detects the requests made by the V1210 but when returning the information it arrives with a 5 in the message status.
