PLM Status remains / Not Connected

[m6bigdog]

Transitioned from an ISY994i/IR Pro installed in 2013, to the Eisy(5226) in 2024 and all was well until:

This week (3/26/2025) the ISY programs stopped and I discovered the PLM LED off.

Replaced the PLM with new module from Insteon, but after numerous power off & reboots into ISY Admin Console the PLM Status remains / "Not Connected".

Troubleshooting:

1)      Installed new PLM 2413U, LED ON then connected the USB cable, power up eisy

2)      Install New USB Cable, repeat step 1 & 4

3)      Use another USB Port, repeat step 1 & 4

4)      IoX Finder - Admin Console (LAN) – ISY loads all Programs & all +48 Devices

5)      PLM factory reset & reboot, ISY Tools/Diagnostics/PLM Status/Not Connected

6)      File/Restore Modem (PLM) constantly cycles (0-100%) without “write update to devices”

7)      Eisy will not perform a factory Reset (Multi-Function Button depressed = x10)

      Numerous, Power On Restart & Reboot: ISY Tools/Diagnostics/PLM Status/Not Connected

Notes:

9)   Firmware IoX v.5.8.4 (2024-06-27-11:35:44)

10)  Internet Access: Disabled

11)  Config/System/Network: settings DHCP (check-gray) and IP address is 0.0.0.0, cannot be changed.

12)  Config/System/Clock: Change Locations, yields, Date correct, time -8 hrs. with Sunrise & Sunset resets to 12:00:00 AM.

13)  Config/System/Clock: Change Locations, not saved in Clock Bar after changing tabs or reboot.

14)   Tools LOG: UDReport.txt, 1st Error     0            Wed 2025/03/26 02:23:30 PM

Questions:

How can I test the PLM and/or eisy USB ports to determine which is the problem.

Is it possible to do a eisy "factory Reset", then reload devices & programs from recent IoX Backup file, then Restore PLM?

It would seem there is more than an PLM Not Connected issue with the "Config/System" issues

Other Diagnostics/Troubleshooting Suggestions??

Thanks

I had to reboot my new eisy several times to get it recognized. Then it was fine

I have powered ON/OFF & rebooted the Eisy & PLM more times than I can count.

For a day plus, nothing I have tried has connected the PLM!!

Given all that you have attempted I would suggest opening a support ticket with possibly BOTH UD and Insteon.

It's quite possible that in all that you've done the eisy is in a state of "shock" (i.e. too much going on that it's not correct). That's why I'm suggesting a ticket with UD.  UD might have a way to test if the eisy is seeing the communication with the PLM at all.

If the PLM is new (as you implied) perhaps getting support from Insteon (https://www.insteon.com/support) might be the route to see if it's something they need to replace if in warranty. Insteon might be able to figure out if the device or cable are bad. I'm not familiar with their troubleshooting steps.

@m6bigdog

Have you tried replacing the USB cable

What is your UI version?

Make sure the PLM is totally booted before you power up the eisy. If it is like the older ISY994i PLM detection is during its boot up.
