jere Posts: 1 Rating: (0)	Is it possible to create TCP Fetch Passive connection via industrial ethernet (PN port). Previously this was done via CP cards, but now I'm using PN cpus. Communication partner is not siemens device, but normal PC with ethernet cardwhich uses open source communication libraries.This is used to grant PC direct access to cpu memory area.Normal communications were successfully implemented with T-blocks (active/passive send/receive), but this passive fetch communication is a problem! Is the problem only in parameters in TCONN structure (UDT65) or is this impossible to do without CP. All communications is done via TCP/IP. Thanks forhelp in advance.
