Can two emulators of AC800F controller running on different PCs on LAN communicate through TCP/iP send/recv blocks
What is IP address of emulator on both the computer is it localhost/127.0.0.1 or computer physical address ? if it's 127.0.0.1 it's not possible to comunicate via ethernet send and recieve. because to send/recieve unique IP address is required to identify source/destination while communicating. hence use computer physical IP address.
Also check first both computer physical IP address can ping each other. i.e both computers are in same network !
Also not sure if that impacts but switch off firewall if switched on.
Check this link for more info on running emulator on physical IP address @ http://www402.abbext.com/AC-800F-Emulator-q623613.aspx#commentsList624930
