plc-sweep
做上位机/网关开发时找设备地址用的 Windows 工具。不联网也能靠内置的 53964 条离线 MAC 前缀认出西门子、汇川等厂商；禁 ping 的设备靠 ARP 应答抓；扫完按 S7(102)、Modbus TCP(502)、EtherNet/IP(44818)、OPC UA(4840) 端口指纹直接标出"这台是 PLC"。

Could you build this?
Partial The basic UI and MAC prefix lookup are simple, but reliably scanning low-level industrial protocols across varied subnets requires raw network socket manipulation and PLC protocol knowledge.
What it would actually take: The tool requires raw socket handling via WinPcap/Npcap or Windows socket APIs to perform ARP scans and identify silent devices, plus probe payloads for S7comm, Modbus TCP, EtherNet/IP, and OPC UA. The tricky part is reliably identifying industrial controllers without causing network faults or tripping safety interlocks on factory gear. It requires domain expertise in industrial networking protocols and low-level Windows packet crafting.
