Information

✎Note: Since CODESYS V3 was released in version 8.4.66.23102001, only the LX6V FreeTag protocol is available in version 8.2.95.22082802. The Wecon Free Tag protocol specifically refers to the "WECON LX6V FreeTag Ethernet" and "CODESYS V3".
The list of 3rd-party manufacturers' FreeTag protocols is as follows:
1. INOVANCE H5U Ethernet FreeTag
2. OMRON EtherNet/IP (NX/NJ Series)
3. Rockwell CompactLogix Ethenet/IP
4. Rockwell Micro850 Ethernet/IP
5. Siemens S7-1200/S7-1500 Ethenet FreeTag
6. OPC UA Client
7. BECKHOFF TwinCAT

The model suffix (x) means there are optional (G), (W), (AG) model.
