The REDF LED is there because one of the CPU's is in stop mode... Not necessary for initial testing. As advised by JMJ, it is better to tackle the CPU stop problem first. Make sure that no monitoring functions/variable tables are active. BF (bus fault) indicates that the ET200M Profibus link is not ok. If I am not mistaken, a sample project gets installed automatically when you install STEP7? The following link may prove helpful: AO in Redundant I/O |

Dear Phantom75 & JMJ, Thanks for your support, I have configured the intial setup only, without ET200M in hardware and software both. After that I Reset both CPUs and did fresh new complete download and then put both CPU in RUN,but only MSTR CPU(rack 0 slot 3)goes to RUN while standby CPU(rack1 slot 3)goes to STOP mode with EXTF Fault ON for second CPU. REDF LED is ON for Both CPU. I checked in diagnostic for first CPU it shows "Rejection of CONNECT due to different configuration of part-AS" as event, i am also attaching with this post. I am not able to check diagnostic for second CPU as it says connection could not be establishd. To see the diagnostics of the second CPU i have to download separately to it and then it shows diagnostic event as "Link-up/update by master CPU aborted Cause: Rejection of CONNECT due to different configuration of part-AS" Moreover, CPU version in my testing is 414-4HM14-0AB0 V4.5.1 on Hardware, but,my STP7 HW Catalogdoes not have it so i have configured 414-4HJ04-01B0 V4.0. I downloaded and updated also the update files but is not coming in Simatic manager catalog to select during configuration, so i am going with HJ V4.0, i hope it is not creating problem. Do you see any solution to achieve redundancy....! I am attaching the screen shots that might help you.. Regards, Jayesh AttachmentS7400H.zip (337 Downloads) |
