how to get data from slc 500 into freelance 800f graphics display
The first question is ... why are you copying this data to a controller ?
Unless this is a very small amount of data then you should be using OPC to get the data directly to your HMI. RSLinx is a very good OPC server but there are plenty of third party alternatives for an SLC500 - all of which would probably be as cheap or cheaper than buying communications hardware.
So next question ... what sort of HMI are you using ? Digivis, 800xA or some other ? Of course, it shouldnt really matter - youre just adding OPC data onto a graphic.
