On a project with several ION7550RTU the client entered a IP adres but do not know it any more
The ION7550RTU are without a screen.
I tried with wireshark but cannot find the IP adres
Is there a factory (re)setting or other possibility for a IP trace or IP factory?
Thanks in advance
You could use nmap as a tool to scan a range of IP addresses that might be used by the RTU. nmap will report the MAC address. An RTU will have a MAC address that starts with 00:60:78.
Depending on the security settings, an RTU might typically have ports 23, 80, 502 and 7700 open.
The nmap command I used is:
nmap -p 23,80,502,7700 10.168.69.100-150
and it returns, among others,
Nmap scan report for 10.168.69.133
Host is up (0.00098s latency).
PORT STATE SERVICE
23/tcp open telnet
80/tcp open http
502/tcp open mbap
7700/tcp open unknown
MAC Address: 00:60:78:04:56:41 (Power Measurement)
From there you can log into the web page and verify the serial number or owner/tag information.
Hope this helps.
The RTU should send out a gratuitous ARP packet on powerup as well, which wireshark will capture. Filter on ARP and it should show up around 10-15 seconds after power is applied.
