TCP 40000
Synopsis
- SafetyNET p (industrial Ethernet safety protocol by Pilz) uses TCP/40000 (and UDP/40000) for communications between controllers and devices in systems like the Pilz PSS 4000 automation platform.
- Real deployments include Pilz PLCs and safety controllers on factory networks where SafetyNET p handles safety-related data exchange.
- Security note: Internet-exposed SafetyNET p services have been observed in scans of industrial systems, and attackers probing ICS devices may target this port for reconnaissance or exploitation of misconfigurations.
