Greetings Iperf folk I'm responsible for a remote control system for heavy earth moving equipment in an underground mining environment. The system consists of:
1. Windows PC on the surface as the main control unit 2. 4 remote control stations - 1 on the surface, 3 underground 3. Numerous access barrier boxes - controlling laser barrier safety systems 4. Numerous Wifi access points - to connect the loaders to the network 5. 4 underground earth moving front end loaders - equipped with Wifi machine clients Interconnections between all the fixed hardware consist of fibre optic lines to various network switches placed at different levels underground. From those network switches we use Cat6 ethernet cabling to the end devices. 1,2,3 and 5 above all contain a PLC unit which interfaces DC control signals to IP data. If connection is lost between any of these devices the system goes into an immediate fail safe and shuts the machine in operation down. The issue I'm having is lost packet data intermittently causing this shutdown condition. Running various continuous pings from the surface control PC to different IP address locations underground I can determine roughly where the unreliable connections are. Can Iperf be configured to run continuously, say over several hours, and provide more specific feedback on where the system is losing integrity? Any feedback or insight gratefully appreciated. Regards, Patrick Grahvendy AutoMine Specialist
