eWON Cosy 141 - MPI configuration in Step7 5.5

I have an eWON Cosy 141 with MPI port and would like to enable remote connection to an S7-300 using Step7 v5.5. Looking through lots of documents on ewon.biz, it seems to suggest that I need to add the eWON in the NetPro configuration in Step7 and talks about importing an eWon config, or eWON config-winncc station file. All the links I’ve seen directing me to these files, don’t appear to work. Is the configuration of NetPro still a requirement? Where can I access the eWON station files? Is there a document that guides me through the S7-300 PLC MPI remote access using Step7 5.5?

Hi @Glyn,

Was this the page that you were referencing? https://hmsnetworks.blob.core.windows.net/www/docs/librariesprovider10/downloads-monitored/manuals/application-user-guide/aug-0037-00-en-configure-remote-access-for-siemens-plc-through-step7.pdf?sfvrsn=dbb449d7_21

I think that Netpro is still a requirement for being able to communicate with these MPI devices

Hi Tim,
Yes, that was the document I was looking at and it describes the requirement for configuration in NetPro, but the links on page 19 of the document, pointing to the station config files, don’t appear to work. I’ve since been directed to the following link by MAC solutions, which does work.

Were you able to get it working by following the links on that page?

Hi Tim,

I’ve followed the guide and updated my Step7 configuration, but not had chance to get back in to the office and try this out yet. I need to update the eWON side, as this is a new eWON and hasn’t connected to the internet as yet.

Oh ok, let me know if you’re still having issues with it when you’re able to get back in the office
