[?]: 2 cpus s7 300 PROFIBUS connection

Post by omar zedan »

Dear All
I try to write a program in step 7 3152dp take an order from other plc also 3152dp what information I should ask for ?
I read some thing about ways of connection using profibus like (master slave) also there is (data exchange)?
should I ask the other team for memory addressing?
Thanks for help

connect mpi interfaces of your cpu with profibus cable
use global data or put & get for data exchange between cpu`s
