The LEDs indicate the operating state of the processor module. All LEDs should be considered together. The LEDs on the module are divided into six groups:ƒ Module status indicators (Run, Error, Stop, Init)ƒ Redundancy indicators (Ess, Red)ƒ System bus indicators (A, B)ƒ Maintenance indicators (Force, Test, Prog)ƒ Fault indicators (System, Field, Com)ƒ Ethernet indicators (Eth1…4, H/F/Col1…4)When the supply voltage is switched on, a LED test is performed and all LEDs briefly flash simultaneously
