cataliz3er Posted November 4, 2016 Report Share Posted November 4, 2016 Hey guys, I'm using the following piece of code to connect to a Vsision V570 PLC. public void Connect(string ip) { try { var ethernet = new Ethernet(ip, 20257, EthProtocol.TCP, 3, 3000); PLC = PLCFactory.GetPLC(ethernet, 1); PLC.SetExecuter(Unitronics.ComDriver.OperandsExecuterType.ExecuterPartialBinaryMix); Debug.WriteLine($"Connection successfull"); } catch (Exception ex) { throw; } } Most of the time it works, but every now and then I get the following exception: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 192.168.1.210:20257 SB168 is set on. SI 103 - 106 are set to 30. SI 107 - 110 are set to 0. On the PLC in the Info menu > Ethernet > Parameter Summarize: Connect = YES. This leads me to think that sometimes when I close the application the connection remains on, and I have to reboot the PLC to be able to reconnect from the SCADA PC. What should I try? Thanks Quote Link to comment Share on other sites More sharing options...
