Hi,

 

I built a Demo of PLCnext using AXC F 2152 to push 3 data to Proficloud.net

The AXC F 2152 is connected to the WIFI in office.

And I found that some times, the Proficloud will stop receiving data by itself, but the program in controller is still running.

I'm wondering is it because the unstable of the WIFI in office (as many people are using it). Or is there any other possibility?

 

Thanks for your help.

 

Best regards,

Li Zhuoqun

Hi zqli,

in case the connection gets lost will the Proficloud stack buffer the TSD data on the device and will send it after the connection returns.
But of course is this buffer also limited, means when the connection is very very unstable it might happen that some data gets lost.

You can verify this by just using a wired connection or check the output.log (/opt/plcnext/logs/) for any disconnection messages (you can also add it to the post).


Take care,
Frank
