[IMG_20260228_114333] S/E permanently in red color & other I/O cards blinks in a row in green link ..what might be issue..pls help

Hi, Additional to what Valerio answered, see here the LED states, looks like a network / connection / wiring issue: B&R Online Help Best regards!

Hi @Sharan532 , Welcome to the Community! Please upload System Dump.I suspect your main B&R CPU is in service. Ciao Valerio

Hello, maybe check the node number switch. A static red LED looks like DNA (node number 0) or maybe a wrong node number (>239) Best regards, Florian
