Split from Cognex Camara error.

Hi sir, 

I have the same issue MrRunning

I was config connection between PLC and Camera okay, and then i was test all function, it work fine.

But when i turn off power supply and wait some minutes i turn on power supply, the red light on PLC is flash. After that, i open tia portal i see error profinet connection. The camera have an error at function "User Data", then i go to log status of PLC the error logged is as follows: 

"Error: Cyclic and Asynchronous writes to User Data are being performed. Please choose only one method on Input/Output channel 1 Insight/UserData - 64 bytes."

At that time, the PLC can still read status "Online/Offline", "Result 64 bytes" of Camera, only  function "User Data" not work.

Do you have any method for solve this issue?

Hello, 

I was created new project (don't have code in program, only config communication). This issue still happen.
