✎Note: The Wecon Free Tag protocol specifically refers to the "WECON LX6V FreeTag Ethernet" and "CODESYS V3". So for example at the columns for Upcoming Release, all models from 3000ig CAN ONLY use CODESYS V3 to communicate with LX6C, but not able to use CODESYS V3 to communicate with any other CODESYS devices. And please notice that once update the firmware with the newer version, it cannot downgrade with older version PIStudio anymore.
