Engaged Sweeper II

Hello,

 

I'm trying to do a test scan for a 1756-L83E/B card but when I do it only shows the model, IP and MAC. Nothing on the position, bus size, firmware, etc. The scan summary shows it scanned with Profinet on port 65535 or no protocol used at all. I did the default scan and expected it to use Ethernet/IP but nothing. I believe using the correct OT sensor and using network discovery v 4.8.6. Am I missing something?

Thank You

Hi,

The limited data you’re seeing means the OT sensor isn’t actually performing a full EtherNet/IP deep scan against that controller — Lansweeper is detecting the device only at a network‑identity level. This is normally due to the sensor not being at the same level of the network as the asset.


Check that the OT sensor is operating on the correct network segment, that EtherNet/IP port 44818 is open

I also tried just only having that connection when I reinstalled the sensor and the sensor says the IP is 255.255.255.255 and no MAC

I also have the controller directly connected to my laptop. I reinstalled my sensor but I noticed the hub won't recognize the Mac address of it if it doesn't have internet or won't change the IP to what I set on the dongle

How do I setup that sensor to be on the same network segment? I do see the sensor assigned to my wireless card's IP and I have an Ethernet dongle plugged into my laptop and I configured the IP and subnet mask to be on the same segment as the controller on the Windows side but when I try to configure it on the sensors tab in the Network Discovery, it only allows me to change the Max Parallelism
