Hi Aleksei,
I checked your video and program.
- communciation issue when com port is master, I downloaded same monitor tool to test what you said, but not redupliate your issue. The bytes are continuous.
- Write Error
T3000 already fixed this issue, it is caused by reading too many points in one graphic and stucked. when you upadte latest T3000, it will be ok. - Program code is turn off automatically.
I loaded your prog, I guess T3-XB is too strict to check runing time of every program. I should do someting to avoid it. If it exist dead cycle, it will jump out, so the prgrom can not running correct, and generate an alarm. If the program just runing too long time by accident, it will generate an prgram alarm too. You can turn on it by hand. I will upload a new firmware to subdivide the two error.
