Hello experts, I have difficulties at here. I have two identical PLC [CPU 414-5H PN/DP, O/N:6ES7414-5HM06-0AB0, V6.0]. I also have TWO (2) ET200M/LINK IM 153-2 connected with these PLC. 2. The problem came when my redundant PLC is not RUN (STOP mode) while the master PLC is running finely. I tried to STOP the master PLC and letting the redundant PLC to takeover but unsucessful which the RUN keep blinking at that moment 3. Currently LED status at master PLC have REDF led lit solid while redundant have REDF and EXTF LED lit solid red. For ET200M, the redundancy PLC connected to it have SF led blinking. 4. Based from latest diagnostic message from redundant PLC, it provided error event 16#5371 which is Event 1 of 120:Event ID 16# 5371 Distributed I/Os: End of the synchronization with a DP master/IO controlleron slot3 in rack1 Number of distributed stations:1 Event occurred in the standby CPU in rack 1 Incoming event 04:47:04.177 PM04/17/2019 (Coding: 16# 5371F1230050000100000000) 5. I checked the DP cable connected to ET-200M even swapped with the one from master PLC, still NOT working. 6. I configured the monitoring time by increasing it from 650ms to 900ms.NOT WORKING 7. I even downloaded the whole program again into both PLC. NOT WORKING So, I need ASAP advice from experts. Thank you. Attached is the full diagnostic message for your kind perusal.

Hi Sachinpatke, Can you be specific regarding download the OB 86? Is it to download to both PLC? I already downloaded the OB86, and put the Watch On. Nothing is happening at there. What do you expect me to see? So maybe I can get a clue from your advice. By the way, my PLC is actually S7-F system. Currently used it for safety system. Thanks in advance. |

Hi afz2004, The the entry you mentioned is never responsible for CPU stop if OB86 is available.(See event 5). Remove the FO cable, download program & check whether both CPUS are going to RUN mode or not. |

Thank you for the suggestion. However,it still not resolved the PLC. Any other idea? Like today, I just swapped the IM module just to troubleshoot if the IM module is faulty or not. In fact of matter, it is working OK. I am sorry for troubling you so much, I am not that really good in safety system configuration. Hope you not bothered with my silly questions. |
