S7-300 MPI & Ethernet connection

2 posts in this topic

Hey all,

 

long time without posting, I don't know if i'm writing in the right place.

 

I have some old PLCs S7-300 ( and a couple of S7-200) that I would connect to the same general network in order to see all data from a general SCADA (I'm thinking about Ignition but could be WinCC etc).

 

First problem is that few of them don't have an Ethernet Card (still old MPI) and I'm searching for a converter.

I've found something on internet that I could install, probably no big issues on this side.

 

Main problem is that others have an Ethernet connection but they are programmed to work on their own network (indipendent machine) and I couldn't change all IP addresses.

I need probably a Gateway (eWon??) but I would understand better how it works.

Any suggestion?

 

Thank you in advance for your help!!
