Adding ADS route failed #79

Closed ZhousuLee closed 5 years ago

ZhousuLee commented 5 years ago

I am trying to run the C++ example (on Ubuntu 16.04) to connect to your "PLC-TestProject" on TwinCAT 3 running on a personal computer with windows7 system . I set IPV4 address of windows 7 to 192.168.0.231 and set AMSNetId of Twincat3 to 192.169.0.231.1.1 I set IPV4 address of Ubuntu 16.04 to 192.168.0.1 When I run the c++ example (on Ubuntu 16.04) after running "PLC-TestProject" on TwinCAT 3 ，Ubuntu always show me that “Adding ADS route failed”. I have tried ADS communication between two personnal computer both with windows system, and it works well. I could add route manually by click " Router/Edit routes" because both of computers have Twincat3. So I am not sure whether i need do this when one of computers is Ubuntu system. I am new to ADS so it maybe very easy. Thanks a lot.

I guess this was just a typo? "192.168.0.231 and set AMSNetId of Twincat3 to 192.169.0.231.1.1" and you meant "192.168.0.231.1.1"

Then the remoteNetId in the example would already be correct: https://github.com/Beckhoff/ADS/blob/781d7668502de67afbaae07130088da5c6f61e45/example/example.cpp#L180

But did you adjust the remoteIpV4, too? https://github.com/Beckhoff/ADS/blob/781d7668502de67afbaae07130088da5c6f61e45/example/example.cpp#L181 Replacing ads-server with 192.168.0.231 should work for the setup you described.

You solved my problem perfectly .I forget this step:

Replacing ads-server with 192.168.0.231 should work for the setup you described.

Thank you very much.
