UnniDDE to Microsoft Access in UniDDE Posted June 28, 2018 · Report reply Goodmorning, I have a customer who wants to use Microsoft Access to read the MI's from the PLC. I have done this before with excel and that works fine for me. But Microsoft Access isnt working at the same way and i cant get any connection with this program. Normally you make the right connection with UniDDE and than copy the read Command to excel. I thought this worked in the same way for Access. The Project: In the project every data of "MI 1" has to be added in the Microsoft Access Database. The Incomming Mi's will be sorted by date. Is there anyone who can help me out with this problem?
