i have open office calc (open offices spreadshhet) talking to a dl205 via dde using dsdde. you will need dsdde to interprit the dde commands from windows to the plc, then its just a matter of setting the right syntax from the cell to extracting your value. =DDE("dsdde";"Koyotopic";"x00") is the arguement for the cell in calc excel will be simmilar, i recall it contains the pipe charactor somewhere, i think between the topic and the application. cheers,
