Hi, it just tells you that you can click the flashlight in order to see a message on the PLC (to identify the PLC).

The warning sign appears probably because there is a version mismatch... Either the PLC has  a newer firmware related to UniLogic, or the opposite around. (Most likely that the PC has a newer UniLogic version, for example 1.24.56, while the PLC has firmware 1.23 or older).

Either by USB Stick or by remote upgrade (through communication).

USB Stick

1) plug the usb stick (disk on key) on your PC

2) In UniLogic: PLC -> UniStream Management -> Firmware manager -> Copy to DOK

3) Plug the USB Stick on the PLC, and in the UniApps  upgrade the firmware (in one of the menus)

 

Remote Upgrade: 

1) Make sure the PLC is connected to the PC with USB

2) In UniLogic: PLC -> UniStream Management -> Remote Update

3) Select the PLC from the list, select target drive (External SD, or DOK)... You either must have an external SD in the SD Card Slot, or a USB Stick plugged into the USB Host of the Panel

4) Click on Update

5) When the firmware is sent to the PLC and you get a message that the PLC is rebooting, unplug the USB cable from the PLC and wait for the upgrade to start and finish (it may take a while, depends on how many files it needs to update.

It might be stuck in the upgrade process. Give it another 30 minutes.

If it doesn't finish by then, then contact our support. Someone from the Panel R&D team will need to recover the panel, or then will instruct you how to do it.
