Anybody ever find an ActiveX OCX to allow a PC based Visual Basic or C++ application read and write directly through an ethernet port to any Ethernet/IP Remote I/O system? I want to write a PC based controller / HMI to read and write to 256 inputs and 256 outputs via a common PC RJ-45 Ethernet port. Open source would be much better then some proprietary source. I goodled ActiveX Ethernet/IP remote I/O and get just crap. ActiveX data aquistion is better, but the companies who offer the ActiveX want $900 per year for the license, which seems a bit high. I have used CimQuest ActiveX for AB PLC's in the past. let me know if you have heard of any kind of new tech for this. thanks, M.G
