Hi, In Siemens S7 PLC's it is indication for PLC being unresponsive. They call it Tannenbaum (Xmass tree). I never heard this to happen with S7-1200/1500 but I assume it is the same thing. Have a look at this thread regarding to S7-400: A useful link for diagnose S7-1200: How do you proceed when peripheral device errors are detected by the S7-1200? I hope I could help a bit. |
