Dear Experts, I have redundant CPU 414-4H (6ES7 414-4HM14-0AB0) along with PCS7 V7.1, what i observed is that after 3-4 hrs all LEDs of the CPU start blinking RED this is happening from last 2-3 hrs since we commissioned the plant. Client is asking the reason and i am blank i have no clue why this is happening. For making it normal we are erasing memory and recycling the power of the Redundant modules and then it starts working properly. Is it requires firmware update? or any internal issue in CPU AttachmentDiagnose_CPU_414-4h_redundant_10052015.txt (363 Downloads) |

Hi, Firmware update is a big massive change. Maybe a bit risky to do it online. See this thread:CPU 414 firmware upgrade Anyways it is detailed how to do a Firmware update in Run see the SIMATIC Fault-tolerant systems S7-400H manual under chapter 6.5 Firmware update in RUN mode. Maybe talk to Siemens Support about the procedure and how it can effect your compiled code. I hope I could help a bit! |
