Target port not found ADS Server not started (6) #53

Closed f-scotto closed 6 years ago

f-scotto commented 6 years ago

Hi All, I am trying to control some variables on the PLC through pyads. Unfortunately I keep on receiving always the same error message. 'target port not found ADS Server not started (6)'. Any ideas on how to get around this issue? Thanks a lot in advance.

`import pyads

plc = pyads.Connection('10.2.9.142.1.1', 851) plc.open() plc.read_device_info()`

Did you install Twincat on your PC and setup the routes to your target properly?

f-scotto commented 6 years ago

Yes, The route is setup correctly and the twinCAT is running on my machine. I have uninstalled and installed the whole system but whenever i try to get the read_device_info form the pyads.Connection('AMSNetId', 851) I get the same error message. (target port not found ADS Server not started (6)). I cannot figure why!?

If I run the TcAdsTest I get this error message (see pic). capture

This clearly looks like you've got an issue with the setup of your TwinCAT system. Unfortunately I can not help you with this as it is not related to pyads. Maybe it helps to check if your Beckhoff ADS library is installed correctly on your system.

I got the same problem. Have you solved that?

Solution that worked for me: In TwinCAT, project explorer, right-click your project name under "PLC" branch, and click Change ADS Port. it should be 851 normally. if it is not, update your Connection initialization accordingly.
