Hello again,
I am using excel to extract data from a PLC.
I can link and transfer data back and forth from a work sheet but I am wondering why I have to transfer from the sheet and can not just transfer directly from VB.
This is what i use...
RSIchan = DDEInitiate ("RSLinx", "Turbsim")
DDEPoke RSIchan, "F8:5", Range("[turbine_sim.xls]GTCLRC!A57")
DDETerminate (RSIchan)
What I would like to do is not have to run a calc back to the sheet first to transfer the data.
Something along these lines, but I cant get it to work
DDEPoke RSIchan, "B3:0/7", MyVar
Where "MyVar" is some calculated value.
Any Ideas?
