If you are facing blinking LED after firmware upgrade within old UID-0808T IO module (Boot version 0.10) we would like to offer the following solution.

• Disconnect all the IO from the CPU.
• Connect only the UID-0808T to the CPU.
• Check if the I/O module can be recognized by the panel (Go to UniApp > System > I/O Units)

For example:

Let us know what is the BOOT version.

If the boot version is 0.10 (and lower versions), please try the following:

• On UniLogic go to Download > OS Download > Download IO Files.
• Select the IoOS_UID-0808T_V2_5 and press download.

• When it's done, reboot the PLC.

Please note that you cannot use the "scenarios" of this IO module with OS V2.5.

Then connect back all the I/O and download a project with the exact hardware configuration order.
