The U-CON Protocol Server supports unsolicited transactions over Ethernet Encapsulation, which requires a Serial-to-Ethernet converter that can be configured to initiate connections and reconnections to the PC and port being used by the server. Kepware's "UNSOL_Eth_Example.zip" contains a sample project that is configured to receive data from a weigh scale through a DIGI One IA (which is configured to do an automatic TCP connection back to the PC running the server).
