Error: Could not open config file (IoX 5.8.4)

[MickBehr]

When attempting to change/modify the PLM Communication, I always get this error on any Insteon device, how do I fix (or just keep ignoring?) Could not open config file to read [./FILES/CONF/INSTENG.OPT]

@MickBehr This could mean a couple of things. It could be a corrupt IoX upgrade (if you upgraded recently) or could mean the PLM has failed. More than likely it's PLM related.

How old is the PLM? What style (serial or USB) is the PLM? How is it connected to the eisy (what cable(s) are you using)?

Has this worked previously and this is suddenly new errors? Or has this always happened since you updated to 5.8.4?

What computer OS are you running? (Windows, Mac, other)

I would suggest:

• Check the PLM to see if the light on the side is on and green
• close Admin Console
• Shut down the eisy (https://wiki.universal-devices.com/Eisy:User_Guide#Multi_Function_Button)
• Unplug the eisy
• Unplug the PLM
• Wait 20-30 seconds
• Plug in the PLM (allow light to stabilize - about 30-60 seconds)
• Plug in the eisy (allow 2-3 minutes for it to fully boot)
• While waiting for the eisy to initialize
  • clear your java cache (be sure to check all 3 boxes in the process)
  • Download a fresh copy of start.jnlp from UD website (https://isy.universal-devices.com/start.jnlp)
  • Run the file to put the IoX Launcher icon back on your desktop
• Open Admin Console and allow it to fully load
• Select random device

Do you still get the issue? If so, check the status of the PLM:

• Admin Console -> Tools -> Diagnostics -> PLM Info/Status

If you don't get a "Connected" status then you know the PLM (or the connection to the PLM) has failed.

If the PLM is okay then it's possibly a corrupt update and you should run the "Upgrade Packages" process again and allow it to complete before being rebooted. 

This might require further troubleshooting with UD so you might want to open a support ticket:

But depending on the age of the PLM I would suspect it has issues. 

Be sure to keep the wiki handy if you end up having to replace the PLM as it has the steps to follow for PLM/Modem replacement.

This has happened ever since I was using my 994i, and through to the upgrade to using EISY. Since the old modem on 994i died it was replaced, and then replace again when I upgraded to EISY - so the error was present in all three configurations. The EISY is connected via USB to the PLM. Always running macOS, currently 15.01

Checked:

PLM Powered on + green light.

Shut down EISY and PLM, unplugged both, and rebooted

Clear Jave cache, reinstall IoX Launcher, launch EISY, pick random device, change PLM retries, still get the error.

Checked PLM info/status - Connected

Ran "upgrade packages", and rebooted when told to do so.

Tested again, still fails
