ION7550RTU Forgotten IP adres

[YvesR]

Hello,

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.

Have you try using ION Setup via serial port ?
