Sam.Newtouni Posted August 25, 2020 Report Share Posted August 25, 2020 Hi all, Hoping for some assistance here. I have a new remote IO unit that I'm trying to bring online. The issues I'm having appear to be with the TCP connection, I've attached a sample program of my main routine and modbus. I have green/red flashing light on mod, green on link & solid red on IOS, on first startup I get a few flashes on active. Things to note; - I have remote access setup on the same socket & it still functions ok - I have tried removing that port init with no luck. - I can ping both the CPU & URB IO controller from my PC so no issue with actual network connectivity. - I haven't looked too much into the modbus code because the Socket is not healthy & that is holding those rungs out anyway. - When I don't have a program attempting to make a TCP connection I have A green light on IOS,LINK & MOD - I have verified the project with URB configuration & also attached that file.FORUPLOAD.vlp Here are some pictures of what I am experiencing when I'm online. Any help would be much appreciated. Cheers, Sam Quote Link to comment Share on other sites More sharing options...
