315-2pndp, BF is blinking

Dear All,

I am configuring Siemens 315-2pndp cpu with im153-4 hf. It was working fine but by mistake i selected cpu in netpro and download. After that BF is blinking in Im153-4 and SF is consistent and BF is blinking in CPU. I tried everything but the fault is not going. In diagnostic bufferit is showing "wrong partner" and " faulty module(diagnostic interrupt detected" type of messages are coming.

Please help me step by step. I am in very bad situation.

Split from when install the memorycard i get an SF.

Hi,

which changes you have done before you download?

Check the Names of the devices that there are the same in the project and the targets.

After power off/on the PLC is the error happen again?
If not upload the HWConfig from the PLC to a new empty project and compare it with your project which is not working.

Regards

Christoph
