Hello, does anyone know the best connection method between an S71500R/H profinet MRP ring (2 x S7 1500R controllers in redundant profinet ring) and an S7400 DP Master ?
Describe a bit more about the existing S7-400 and its existing DP system. "it already has a DP connection" tells me nothing.
Describe what the new connection between the existing S7-400 and the new S7-1500R system is supposed to achieve.
Not sure if Siemens have PN / DP gateway for this.
But you can use Helmholz directly on MRP or with PN/PN coupler.

You dont explain what you need to achieve.RS485 connection from existing S7 400's CP that is a DP master. I will be transferring only 15 bytes of data cyclically both ways. I need to know a recommended converter that will act as a gateway from the DP master to the S7 1500 via its profinet S2 MRP ring.
Seriously ?!Lare said:Not sure if Siemens have PN / DP gateway for this.
Seriously ?!
Profibus and Profinet are absolutely central in Siemens product portfolie, the one being the previous fieldbus and the other the current fieldbus around which everything evolves.
The most obvious is to add a CP443-1 to the S7-400 rack. There are plenty other methods.
For a system with redundancy I would stick to an all Siemens solution without 3rd party products in between.
Probably as the lowest cost solution.Lare said:They recomended 1200 CPU with profibus card between which sounds ridiculous.
