I have faced a problem with this codesys 3.5.9 for Raspberry Pi.
I have not purchased the license but was told that there is a 2-hour demo which runs the codesys for 2 hours. But when I use the codesys trying to link to the RPI, I can scan the RPI for once. After I rescan it again, it disappears.
Is it that this 2-hour demo has been ceased in 3.5.9 version? Anyone has the experience?
