I am using PROFIBUS DP with CP 5711. How can we communicate and get data?

To get data with nodes7 over PROFIBUS there are two requirements:

1 The device you are talking to has to support the S7 protocol, which limits you mostly to Siemens PLCs and some VFDs
2 You need a converter that converts S7 messages from Ethernet to PROFIBUS. This has to be something like a IBH or Helmholz Netlink, not a 5711.
