Hi all. I connected my pc to a plc. Using a DDE connection I established communication between Excel and the PLC. I have in cell A1 connected the parameter weight. So, whenever there is a new value, cell A1 updates and I can see the value. So far so good. I want to save the values. Is this possible? I want to run a macro whenever the value is changed and save them. All I see so far is a cell updating. Thanks.
