Hello Experts, I have a SICK barcode scanner CLV620-0120 which has 200bytes input and 200byte output memory, it has an Ethernet/IP port, I can connect it to Allen Baradley CompactLogix L32E with Ethernet/IP port easily and got the scanning result. Allen Baradley Ethernet/IP port provide memory mapping configuration, but I couldn't get the mapping from SIEMENS's. I don't have any idea on how to connect it to SIEMENS S7-300. I tried to connect it to CP-343-1 Lean through a switch, it can be connected, but I don't know how to get the data that passed from SICK barcode scanner. Please help.
