Warning: Reading/Writing is not permitted

Warning

This warning may appear when connecting a camera.

Solution

The warning indicates that a write or read command that TwinCAT Vision sends to the camera is not allowed. This can happen if the definition of the access rights on a register in the GenAPI description deviates from the actual behavior of the camera. Usually this camera register is unimportant for the user. To ascertain which register this concerns, you can search for the displayed register address in the Configuration Assistant.
