hi to all!!!

i'm new in plc´s and i am starting with the s7-200 of siemens. I would like to know if someone made a ppi network because the information in the manual system is not very clear.

Has anyone made a ppi network, can explain a little please?
Why not using a mpi network?
the differences between mpi and ppi and the advantages of mpi over ppi?
How do i know which protocol suites more to my control process?

Cheers! any link or information would be great,

Hello,

the best information about PPI networks is in the chapter 7 of S7 200 Manual.

A bit of explanation: S7 200 family due to made the product cheaper as possible support only PPI protocol, MPI is available as slave, same as profibus by using optional EM277 Module.

If you have S7200 CPU's you can use only PPI protocol, no other way :)
