The scripts I wrote use the device discovery mechanisms of this protocol to find devices on a network segment. It's complicated and it is mostly being used for the engineering software to interact with PLCs on the network even though you can do a lot more with it. It supports routing between different network segments, tunnels higher layer application layer traffic between devices and so on and so forth.
It supports different physical layers like serial links, CAN, but also Ethernet using UDP or TCP. This runtime has a custom network protocol that contains multiple protocol layers. This patch adds two NSE scripts which allows device discovery of Codesys V3 based PLCs on a network.Ĭodesys is a widely used PLC runtime licensed and customized by different automation vendors. | Device manufacturer: TwinCAT Profinet I/O | Device manufacturer: TwinCAT PNIO Controller | Device manufacturer: WAGO-I/O-SYSTEM 750/753 nmap -e enp8s0 -script broadcast-pndcp-discovery This script sends a standard DCP Identify request and parses all the responses it gets back from the devices on the network. DCP is a subprotocol of Profinet which is used for device discovery and configuration. Profinet is an industrial Ethernet fieldbus protocol suite. This patch adds an NSE script which allows device discovery of Profinet DCP devices on a network.
