Limitation of the Ethernet communication protocol

The table below shows the maximum number of communications configured for the general protocol, Free Tag Protocol and CodeSys V3 Protocol on each series model.
 (**Only HMI V2.0 System supports Free Tag Protocol and CodeSys V3 Protocol**)

✎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 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.
