From: "Marius-Simion Cristea" <cristea12 () yahoo com>Hi,I want to capture the traffic (the commands) that are sent from a SCALANCE touch panelemulator to a PLC. The configuration of my network looks like this: Emulator---HUB---Scalance_Switch---PLC | PC (Wireshark)I'm giving commands to the PLC from the emulator, the PLC responds, but I can't capture any of those commands using Wireshark, i'm seeing only ARP, LLDP, PN-DCP packets and someother broadcast packets.Is it possible to capture those commands using Wireshark? if so, what am I doing wrong? because, as far as I know the hub must send all the packets that are meant for the PLCalso to the PC. Thanks!Maybe I am off but... Instead of Emulator---HUB---Scalance_Switch---PLC | PC (Wireshark) Go this route...Drop an Ethernet hub between the Scalance_Switch and the PLC and sniff from that POV.{ Of course making sure the PC w/Wireshark has a promiscuous NIC } Emulator---HUB---Scalance_Switch---HUB---PLC | PC (Wireshark)
