Hello everyone, I am a student of electrical engineering, in my project I should use the form SOMPLC-F28PLC83 but I can not understand some things ...
Reading the various documents, I saw that lacks the coupling transformer and the one recommended can not find it, how do I fix this?
To communicate with the PLC, use a microcontroller with UART but I can not understand how to do, like check an address, and so on ... There is a document that explains this?
Thank you all!
