Dear All I encountered a problem in S7-416-2DPCPU, that all the LEDs start blinking and PLC goes to inaccessible mode. After restart and download program everything became normal. I want to know the cause, and preventive action to be sure that the problem will not repeat again. Here i attached a diagnostic buffer for reference. Thanks in advance.

Hello Rahul; See if the information and the suggested links in the following discussion can help you out: In what case can this all LED flashing occurs if there is a software problem? Hope this helps, Daniel Chartier |
