Application for distributed block wherein AI-1 and AI-2 are the OPAS input blocks which is giving the input to the PID via selector and PID is connected to the AO block. I have attached the project for the reference.

Now want to distribute the AI-1, IS, PID and AO to FB-1 and AI-2 to FB-2.

So, both FBs working correctly checked independently.

AI-2 block data is always coming as the 0, so wanted to is public subscriber connection is proper . Is it the write way to connect the user defined out to the any as in the publish/subscriber block.

Hi,

you can simply connect the struct output to the SD_1 input of a publish_1 block to publish the data of a struct. The same on the receiver side. You only need to take care that both PUBLISH and SUBSCRIBE have the same number of data points and that they have the same data type.

I hope this helps.

BR,
Alois
