Understanding of pymcprotocol #2

Closed mes20a42 closed 3 years ago

mes20a42 commented 3 years ago

Hi there, thanks for your effort in making this package. I would like to understand the following questions 1) Is it possible to read and write data via ethernet module of the PLC ? 2) Can I control the reading occurrence as from what I understood it seems like the function (batchread) is continuously reading from the PLC

Thanks in advance Eason

Thank you for using pymcprotocol.

  1. Yes. You should use setaccessopt method. You can change protocol header. https://pymcprotocol.netlify.app/_modules/pymcprotocol/type3e.html#Type3E.setaccessopt Please change protocol header for your network structure.

  2. No. pymcprotocol does not support monitering condition.

Best Regards, Yohei Osawa

I'm going to add monitering condition in next major update. Thank you for your suggestion!
