I have two computers using the same version of RSlinx. I also downloaded the EDS files from Turck to read the I/O. I registered the .eds files using the RSLinx tool. One machine can read the I/O devices, the other can't. One was set up about 2 years ago (the one that works OK), the other is being setup now. I am wonder if I am missing a file that allows RSLinx to read those Turck .eds files or if I am missing something. I checked the topics on both, they are the same. Any help?
