Multipoint in CP341 in Modbus Master Mode

Dear Friends,

I have a question about CP341 in Modbus Master Mode when it is connected to 3 slaves; first of all I just need some data from slaves, for this I use 3 send function block (FB120-SEND_341) for sending the function codes for slaves, and in receive side I don’t know what should I do ? Do I should use just one receive function block (RCV_341- FB121) for getting the information from different slaves to a shared data block? Do I extract data of different slaves from this data block?

Thanks in Advance,

Saeed

Dear Late,

Thanks for helping me, but after I read the mentioned threat I didn’t get my answer and I still have a problem for reading data from more than 1 slaves and actually I confused with this one.should i write sequential program to read slaves one by one continusely ?

Waiting for some guideline.

Thanks in Advance,

Saeed
