Hello vasyya; Do you have any information suggesting that SMB is used for program transfers with S7 CPUs, over port 455? I do not see how Step 7 would use NetBios, since the CPUs have a proprietary OS that does not include Windows functions. https://www.poftut.com/smb-port-port-number-protocol-uses-port-445-port-139/ Hope this helps, Daniel Chartier |
