WECON LX series PLC has two ports for programming. HID mode is used for mini USB port in new PLC to make the communication is more stable.
The PLCs produced after March 2016 use new mini USB mode, and require new WECON PLC editor (V1.1.0 or later). The old WECON PLC editor can’t support new PLC anymore, so please update your WECON PLC editor software.
