Hello! Our basic setup seems to be working fine. The device is onboarded and online with a static IP Address from the plant's segment. To test out data mapping we created a simple integer variable in a fresh datablock. However, we don't seem to be able to read this simple variable. We get the following information from the log file:
2019-07-11 12:51:40,210 | : Agent onboarding is in progress...
2019-07-11 12:52:01,964 | : Agent onboarded successfully.
2019-07-11 12:52:07,602 | : Cloud connection is successful.
2019-07-11 12:52:19,198 | : Agent onboarded successfully.
2019-07-11 13:16:12,079 | : Connection successful PLCPlant_8fb059bf-084
2019-07-11 13:16:12,646 | : External data source read failure PLCPlant_8fb059bf-084
Any idea on what could be the problem? Must the read variable be part of a dynamic process?
Thanks in advance.
Solved! Go to Solution.
I think we need a little more Information about your configuration and the settings of your PLC Program.
I can list you some Problems, I have in the past.
Maybe you can send us some Screenshots, than we have mor Information, and give you a detailed answer.
Hi @Steffen1 !
Thanks a lot for replying.
1. Im using S7, PUT/GET communication is enable. I attached a screenshot.
2. The address im using is for variable TString (although it is actually an integer) with the address DB1.DBW2. Also with a screenshot.
3. I dont have any security additional security settings. Attached is also a screenshot of the PLC's security tab.
NodeId is only relevant in case I was using OPC UA, right?
Please let me know if you have any ideas or if you need something else from my setup.
thanks for the Screens.
I have some more questions to you
