tlightne Posted March 14, 2023 Posted March 14, 2023 None of my Insteon devices are communication with Polisy. Event viewer shows PLM not initialized. I tried restoring the PLM and get cannot communicate with PLM. I have a second PLM that I bought used and tried to restore that that one but get: Do I need to delete PLM first before doing restore? Is there are process in the WIKI to replace the PLM? I could not find one. Thanks..
elvisimprsntr Posted March 14, 2023 Posted March 14, 2023 Serial PLM with RS232 to USB adapter, or USB PLM? Model?Have your tried to communicate with it using a console or command line tools?

Was it communicating previously, or is this a new installation or did you just update? Is the Insteon Support box still checked on the Configuration tab? What firmware & UI version and do they match? Edit: Check all your cable connections with Polisy off. Maybe unplug them and plug back in. The procedure is in this document:, even though it's based on ISY, procedure should be the same: https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:File_Menu Restore Modem (PLM) Replace Modem (PLM) This operation is most useful when you need to replace a defective PLM and the ISY is rebooted with a new PLM. When the communication links were established via the Link Management Menu, the PLM and INSTEON devices adds each device addresses it is linked to, in its own link table. The ISY also reads and stores the PLM’s address at boot up. The ISY stores all the configurations settings of the lighting network. If you are replacing a PLM the ISY will have the old PLM address link stored in it. Warning: Never replace your PLM while the ISY is running because it will assume it is still connected with the old PLM. The ISY will appear to work, but it will be writing the address of the old PLM into the device links, thus you will not see devices updates etc. If this menu option is selected, the ISY goes through all INSTEON devices looking for old and new PLM address links. If an old PLM address link is found, it replaces them with the address of the new PLM and adds the corresponding device link to the new PLM. To replace a PLM: Unplug ISY from the power outlet Unplug the PLM from ISY and power outlet Connect ISY’s port A to the new PLM Plug the new PLM into a power outlet Plug ISY into a power outlet Go to Admin Console and wait for system initialization to complete If you have PRO Series, click on the Battery icon at the top. This will prevent ISY from trying to update programming on your RF devices which are probably in sleep mode Click on the Restore Modem (PLM) menu option In case ISY cannot communicate (or decides not to if an RF device/PRO Series) during the process, you will have a series of nodes with green 1011 icons in the device tree. For each one of those nodes: If an RF device, ensure that the device is in Programming mode Right mouse click | Write pending updates ... If the above procedure fails on many of your devices, it's highly recommended that you follow the instructions for Restore Devices. Edited March 14, 2023 by DennisC Added comment about cables.
tlightne Posted March 14, 2023 Author Posted March 14, 2023 @DennisCThank you. My original PLM and the spare are both bad. I fired up my old 994 and it does not talk to the PLM either so that confirms to me they are both bad.. Guess I will be looking at Insteon's repair service...
tlightne Posted March 16, 2023 Author Posted March 16, 2023 I was able to get my spare PLM to connect to Polisy. I did a Restore Modem (PLM) and my insteon devices do not update status when activated manually. They do talk to Polisy as my programs are working. I also tried a Restore Device with no luck. Suggestions appreciated. Thank you...
DennisC Posted March 16, 2023 Posted March 16, 2023 Here are some troubleshooting steps: https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Tools_Menu#Show_Links_Table In general, try moving the location of your PLM for testing, try a different outlet. Make sure you are not plugging the PLM in to power strip or any kind of surge suppressor. Check your cables. Good luck.
