S7-200, NetR, NetW et Simatic Flexible.

phb Posts: 3 Rating: (0)	Bonjour, j'ai une installation composée d'un Runtime WinCC flexible communiquant ( MPI/DP) avec 3 API S7-200 CPU 224 (ou 222) Des échanges sont effectuées entre ces automates via un script WinCC... ( 3 ou 4 mots par API) est-t'il possible d'utiser NetR/NetW pour effectuer cela .. ainsi j'aurais API1 qui effectue lecture et écriture de 2 mots vers API2 . (Soit API 1 maitre et API2 esclave) et API3 qui effectue lecture et écriture de 2 mots vers API1 ( soit API 1 esclave et API 3 maitre) cette configuration est-elle réalisable ? Comment doit-ton gérer SMB30 ? doit on le mettre a 2 pour API1 et API3 ? Merci par avance

I use a WinCC script to exchange between these PLCs, 3 or 4 words per CPU. Is it possible to use NetR/NetW for that? That way I would have CPU1 reading and writing 2 words to CPU2 (so CPU1 master and CPU2 slave). and CPU3 reading and writing 2 words to CPU1 (so CPU3 master and CPU1 slave) Is this configuration possible? How should we manage SMB30? should configure it to 2 for CPU1 and CPU3? Thanks in advance Hope this helps, Daniel Chartier

As you will find in the attached document, it would be better to setup a single CPU as the only master on the PPI bus, and to use it to read/write to all participants, transfering the data read from one CPU and rewriting it to another if required. By the way this is extracted from chapter 7 of the S7-200 System manual, Communicating over a Network. You will find a link to the manual in the following related FAQ: How is data exchanged between two SIMATIC S7-200 devices in PPI mode?
