Ryan Posted March 6, 2013 Report Share Posted March 6, 2013 What do you have for Socket Inits? Are you trying to connect with port 20256? Welcome to the forum! Quote Link to comment Share on other sites More sharing options...

chavez Posted March 7, 2013 Author Report Share Posted March 7, 2013 Thank you for answer... last night about 1AM 0'clock I solved the problem. I used socket 20257 becasue 20256 was in use (I progamed in PLC 20256 to be used ?!?), and I must use start bit to initialize network. It isnt like in webinars Another problem I have is with readWrite function for reading MF registers for my SCADA program which i progamed in C#.

MVP 2023 Flex727 Posted March 7, 2013 MVP 2023 Report Share Posted March 7, 2013 - Make sure PC is on the same subnet as the PLC address. - Use socket 1, port 20256, at least initially until you work out all your connection issues. - Some PC firewalls can get stubborn and will want you to be on the 192.168.1.xxx subnet - try that (on both PC & PLC) if you aren't already. - Check your cables. You need a crossover cable unless you're using an ethernet switch. - Check your System Bits 141-150 to confirm that the ethernet card is present, initialized, socket initialized, etc. Quote Link to comment Share on other sites More sharing options...
