Hi! I've got a customer that has several SCADApacks at remote sites and I need to make changes in their cellular network system. I have the .pia archive files from these RTUs and can open them in ISaGRAF but I have had zero success connecting to them through ISaGRAF. They have TCP setup and I know the IP addresses but they it gives me a failure to connect error when I try to read from them. It's been a very frustrating experience. I've also tried to connect via the USB and with a homemade serial cable following the pinouts we downloaded from Schneider. Of course the ISaGRAF software is obsolete and not compatible with Windows 10 so I'm using an XP VM to run the software. Any help would be greatly appreciated.
