MAC address on PLC 1769-L16ER-BB1B

[Marcktony]

looking for the the MAC address for this PLC, I count find it in the front or at any part of the PLC itself. connected to the PLC by USB, showing a 0.0.0.0 IP address witch means ethernet has not been set up. I looked into the configuration settings trying to find the MAC/ENET address but it doesn't show.
is there any specific location where I can look for this information? our IT department is asking for this information to set a static IP address.

The MAC address on a 1769-L16ER is shown on a label on the front of the controller. It is listed as ENET Address:

If your label is missing, then you could use a BootP DHCP Tool to help discover the MAC address or use RSLinx to set an IP address for the controller and connect using ethernet cable directly to controller then Windows CMD prompt "ipconfig /all" to display MAC address list for the IP address you set.

thanks for the answer, yes, the sticker is missing. I will try setting and IP and using CND. thanks again.

You could get it set up with a temporary IP and then send a CIP GetAttributeSingle message (0x0E) to class 0xF6, instance 1, attribute 3.

I've used wireshark to sniff out IP/Mac's in these instances

you can also connect to the usb port and configure rslinx for the usb port and find the plc that way. you then can click on the plc and see its configuration and i think its mac address also.

RSLinx won't show it. Onboard webpage will.

Just to let you know guys I could find the MAC by configuring the ip address and using CMD ipconfig /all

Or (old school)

Go to your command window (CMD)
Ping your device.
type ARP /a
the listing will show all the recent IPs that the PC has talked to, and your IP will show the MAC address.

This is the easy way

Use the USB port (Printer USB cable)

I set a temporal IP address, connected using that IP, then I was able to see the mac in RSlinx
