Good Morning @Shafizan_Baharudin,
Please, understand that non-recoverable error faced by M580 PAC can be identified by the LED pattern mentioned in Modicon M580 Hardware, User Guide and shall be recovered by pressing RESET button in the CPS Power Supply Unit.
Once recovered, please export the M580 PAC diagfiles with Control Expert (Help > About... > Technical Support) and contact your local Technical Support.
Best Regards,
Alberto Abellán
